out from the pcf2113x (i.e. r/ w is set permanently to logic 0), the unused ports db0 to db3 can either be set to v ss or v dd instead of leaving them open. name function description rs register select rs selects the register to be accessed for read and write when the device is controlled by the parallel interface. there is an internal pull-up on this pin. rs = logic 0 selects the instruction register for write and the busy flag and address counter for read. rs = logic 1 selects the data register for both read and write. r/ w read/write r/ w selects either the read (r/ w = logic 1) or write (r/ w = logic 0) operation when the device is controlled by the parallel interface. there is an internal pull-up on this pin. e data bus clock the e pin is set high to signal the start of a read or write operation when the device is controlled by the parallel interface. data is clocked in or out of the chip on the negative edge of the clock. note that this pin must be tied to logic 0 (v ss ) when i 2 c-bus control is used. db7 to db0 data bus the parallel interface of the device. this bi-directional, 3-state data bus transfers data between the system controller and the pcf2113x. there is an internal pull-up on each of the data lines. db7 to db0 must be connected to v dd or left open circuit when i 2 c-bus control is used. note that db3 shares the same pin as sa0. in 4-bit operations only db7 to db4 are used, and db3 to db0 must be left open circuit. see note 1. db7 may be used as the busy flag, signalling that internal operations are not yet completed. c1 to c60 column driver outputs these pins output the data for columns. r1 to r18 row driver outputs these pins output the row select waveforms to the display. r17 and r18 drive the icons. v lcd lcd power supply positive power supply for the liquid crystal display. this may be generated on-chip or supplied externally. osc oscillator when the on-chip oscillator is used this pin must be connected to v dd . an external clock signal, if used, is input at this pin. scl serial clock line input for the i 2 c-bus clock signal. scl must be connected to v ss or v dd when the parallel interface is used. sda serial data line i/o for the i 2 c-bus data line. sda must be connected to v ss or v dd when the parallel interface is used. sa0 address pin the hardware sub-address line is used to program the device sub-address for two different pcf2113xs on the same i 2 c bus. note that sa0 shares the same pin as db3. t1 test pad t1 must be connected to v ss and is not user accessible. pd power-down pad pd selects chip power-down mode. for normal operation pd = logic 0. 1997 apr 04 8 philips semiconductors product speci?cation lcd controller/driver pcf2113x 8 functional description (see fig.1) 8.1 lcd supply voltage generator the lcd supply voltage may be generated on-chip. the voltage generator is controlled by two internal 6-bit registers, v a and v b . the nominal lcd operating voltage at room temperature is given by the relationships: v op(nom) = [(integer value of register) 0.08 + 1.9] v 8.2 programming ranges ( t ref =27 c) programmed value range: 1 to 63. voltage range: 1.90 to 6.84 v. values producing more than 6.5 v at operating temperature are not allowed. operation above this voltage may damage the device. when programming the operating voltage the v lcd temperature coefficient must be taken into account. values below 2.2 v are below the specified operating range of the chip and are therefore not allowed. value 0 for v a and v b switches the generator off. usually register v a is programmed with the voltage for character mode and register v b with the voltage for icon mode. v b must be programmed to ff in character mode and v a must be programmed to 00 in icon mode. when v lcd is generated on-chip the v lcd pins should be decoupled to v ss with a suitable capacitor. the generated v lcd is independent of v dd and is temperature compensated. when the generator is switched off an external voltage may be supplied at connected pins v lcd1,2 . v lcd1,2 may be higher or lower than v dd if external v lcd is used. if internally generated it must not be lower than v dd and . 8.3 lcd bias voltage generator the intermediate bias voltages for the lcd display are also generated on-chip. this removes the need for an external resistive bias chain and significantly reduces the system current consumption. the optimum value of v lcd depends on the multiplex rate, the lcd threshold voltage (v th ) and the number of bias levels and is given by the relationships given in tables 1 and 2. using a 5-level bias scheme for 1 : 18 maximum rate allows v lcd < 5 v for most lcd liquids. v dd 4v table 1 optimum/maximum values for v op (off pixels start darkening; v off =v th ) table 2

display system. no external components are required and the osc pin must be connected to v dd . 8.5 external clock if an external clock is to be used this is input at the osc pin. the resulting display frame frequency is given by f frame f osc 3072 ------------- = only in the power-down state is the clock allowed to be stopped (osc connected to v ss ), otherwise the lcd is frozen in a dc state. 8.6 power-on reset the on-chip power-on reset block initializes the chip after power-on or power failure. this is a synchronous reset and requires 3 osc cycles to be executed. 1997 apr 04 9 philips semiconductors product speci?cation lcd controller/driver pcf2113x 8.7 power-down mode the chip can be put into power-down mode where all static currents are switched off (no internal oscillator, no bias level generation, all lcd-outputs are internally connected to v ss ) when pd = logic 1. during power-down, the whole chip is reset and will restart with a clear display after power-down. therefore, the whole chip has to be initialized after a power-down as after initial power- up. the device should be put into display off mode (instruction display control) before putting the chip in power-down mode, otherwise the lcd output voltages are not defined. 8.8 registers the pcf2113x has two 8-bit registers, an instruction register (ir) and a data register (dr). the register select signal (rs) determines which register will be accessed. the instruction register stores instruction codes such as display clear and cursor shift, and address information for the display data ram (ddram) and character generator ram (cgram). the instruction register can be written from but not read by the system controller. the data register temporarily stores data to be read from the ddram and cgram. when reading, data from the ddram or cgram corresponding to the address in the instruction register is written to the data register prior to being read by the read data instruction. 8.9 busy flag the busy flag indicates the free/busy status of the pcf2113x. logic 1 indicates that the chip is busy and further instructions will not be accepted. the busy flag is output to pin db7 when rs = logic 0 and r/ w = logic 1. instructions should only be written after checking that the busy flag is logic 0 or waiting for the required number of cycles. 8.10 address counter (ac) the address counter assigns addresses to the ddram and cgram for reading and writing and is set by the instructions set cgram address and set ddram address. after a read/write operation the address counter is automatically incremented or decremented by 1. the address counter contents are output to the bus (db6 to db0) when rs = logic 0 and r/ w = logic 1. 8.11 display data ram (ddram) the ddram stores up to 80 characters of display data represented by 8-bit character codes. ram locations which are not used for storing display data can be used as general purpose ram. the basic ddram-to-display mapping is shown in fig.3. with no display shift the characters represented by the codes in the first 24 ram locations starting at address 00 in line 1 are displayed. figures 4 and 5 show the display mapping for right and left shift respectively. when data is written to or read from the ddram wrap-around occurs from the end of one line to the start of the next line. when the display is shifted each line wraps around within itself, independently of the others. thus all lines are shifted and wrapped around together. the address ranges and wrap- around operations for the various modes are shown in table 3. table 3 address space and wrap-around operation 8.12 character generator rom (cgrom) the character generator rom (cgrom) generates 240 character patterns in 5 8 dot format from 8-bit character codes. figures 7, 8 and 9 show the character sets that are currently implemented. 8.13 character generator ram (cgram) up to 16 user defined characters may be stored in the character generator ram (cgram). some cgram characters (see fig.17) are also used to drive icons (6 if icons blink and both icon rows are used in application; 3 if no blink but both icon rows are used in application; 0 if no icons are driven by the icon rows). the cgrom and cgram use a common address space, of which the first column is reserved for the cgram (see fig.7). figure 10 shows the addressing principle for the cgram. mode 1 24 2 12 address space 00 to 4f 00 to 27; 40 to 67 read/write wrap-around (moves to next line) 4f to 00 27 to 40; 67 to 00 display shift wrap-around (stays within line) 4f to 00 27 to 00; 67 to 40 1997 apr 04 10 philips semiconductors product speci?cation lcd controller/driver pcf2113x 8.14 cursor control circuit the cursor control circuit generates the cursor (underline and/or cursor blink as shown in fig.6) at the ddram address contained in the address counter. when the address counter contains the cgram address the cursor will be inhibited. 8.15 timing generator the timing generator produces the various signals required to drive the internal circuitry. internal chip operation is not disturbed by operations on the data buses. 8.16 lcd row and column drivers the pcf2113x contains 18 row and 60 column drivers, which connect the appropriate lcd bias voltages in sequence to the display in accordance with the data to be displayed. r17 and r18 drive the icon rows. the bias voltages and the timing are selected automatically when the number of lines in the display is selected. figures 11, 12 and 13 show typical waveforms. unused outputs should be left unconnected. fig.3

code bits 0 to 3 correspond to cgram address bits 3 to 6. cgram address bits 0 to 2 designate the character pattern line position. the 8 th line is the cursor position and display is performed by logical or with the cursor. data in the 8 th position will appear in the cursor position. character pattern column positions correspond to cgram data bits 0 to 4, as shown in this figure. cgram character patterns are selected when character code bits 4 to 7 are all logic 0. cgram data = logic 1 corresponds to selection f or display. only bits 0 to 5 of the cgram address are set by the set cgram address instruction. bit 6 can be set using the set ddram address instruction in the valid address range or by using the auto-increment feature during cgram write. all bits 0 to 6 can be read

instructions only two pcf2113x registers, the instruction register (ir) and the data register (dr) can be directly controlled by the microcontroller. before internal operation, control information is stored temporarily in these registers, to allow interface to various types of microcontrollers which operate at different speeds or to allow interface to peripheral control ics. the format for instructions when i 2 c-bus control is used is shown in table 5. the pcf2113x operation is controlled by the instructions shown in table 6, which also gives execution times in clock cycles. details are explained in subsequent sections. instructions are of 4 types, those that: 1. designate pcf2113x functions such as display format, data length, etc. 2. set internal ram addresses 3. perform data transfer with internal ram 4. others. in normal use, category 3 instructions are used most frequently. however, automatic incrementing by 1 (or decrementing by 1) of internal ram addresses after each data write lessens the microcontroller program load. the display shift in particular can be performed concurrently with display data write, enabling the designer to develop systems in minimum time with maximum programming efficiency. during internal operation, no instruction other than the read busy flag and address instruction will be executed. because the busy flag is set to logic 1 while an instruction is being executed, check to make sure it is on logic 0 before sending the next instruction or wait for the maximum instruction execution time, as given in table 6. an instruction sent while the busy flag is logic 1 will not be executed. table 5 instruction format for i 2 c-bus instructions note 1. r/ w is set together with the slave address. control byte (1) command byte

busy busy not busy data 9.1 clear display clear display writes character code 20 (hexadecimal) into all ddram addresses (the character pattern for character code 20 must be blank pattern), sets the ddram address counter to logic 0 and returns display to its original position if it was shifted. thus, the display disappears and the cursor or blink position goes to the left edge of the display. sets entry mode i/d = logic 1 (increment mode). s of entry mode does not change. the instruction clear display requires extra execution time. this may be allowed by checking the busy flag (bf) or by waiting until the 165 clock cycles have elapsed. the latter must be applied where no read-back options are foreseen, as in some chip-on-glass (cog) applications. 9.2 return home return home sets the ddram address counter to logic 0 and returns display to its original position if it was shifted. ddram contents do not change. the cursor or blink position goes to the left of the first display line. i/d and s of entry mode do not change. 9.3 entry mode set 9.3.1 i/d when i/d = logic 1 (0) the ddram or cgram address increments (decrements) by 1 when data is written into or read from the ddram or cgram. the cursor or blink position moves to the right when incremented and to the left when decremented. the cursor underline and cursor character blink are inhibited when the cgram is accessed. 9.3.2 s when s = logic 1, the entire display shifts either to the right (i/d = logic 0) or to the left (i/d = logic 1) during a ddram write. thus it looks as if the cursor stands still and the display moves. the display does not shift when reading from the ddram, or when writing into or reading out of the cgram. when s = logic 0 the display does not shift. 1997 apr 04 26 philips semiconductors product speci?cation lcd controller/driver pcf2113x 9.4 display control (and partial power-down mode) 9.4.1 d the display is on when d = logic 1 and off when d = logic 0. display data in the ddram are not affected and can be displayed immediately by setting d to logic 1. when the display is off (d = logic 0) the chip is in partial power-down mode: the lcd-outputs are connected to v ss the lcd generator and bias generator are turned off. 3 osc cycles are required after sending the display off instruction to ensure all outputs are at v ss , afterwards osc can be stopped. if the oscillator is running during partial power-down mode (display off) the chip can still execute instructions. even lower current consumption is obtained by inhibiting the oscillator (osc = v ss ). to ensure i dd <1 m a the parallel bus pins db7 to db0 should be connected to v dd ; rs, r/ w, to v dd or left open and pd to v dd . recovery from power-down mode: pd back to logic 0, if necessary osc back to v dd , send a display control instruction with d = logic 1. 9.4.2 c the cursor is displayed when c = logic 1 and inhibited when c = logic 0. even if the cursor disappears, the display functions i/d, etc. remain in operation during display data write. the cursor is displayed using 5 dots in the 8th line (see fig.6). 9.4.3 b the character indicated by the cursor blinks when b = logic 1. the cursor character blink is displayed by switching between display characters and all dots on with a period of approximately 1 s, with the cursor underline and the cursor character blink can be set to display simultaneously. 9.5 cursor/display shift cursor/display shift moves the cursor position or the display to the right or left without writing or reading display data. this function is used to correct a character or move the cursor through the display. in 2-line displays, the cursor moves to the next line when it passes the last position (40) of the line. when the displayed data is shifted repeatedly all lines shift at the same time; displayed characters do not shift into the next line. f blink f osc 52 224 ---------------- - = the address counter (ac) content does not change if the only action performed is shift display, but increments or decrements with the cursor shift. 9.6 function set 9.6.1 dl ( parallel mode only ) sets interface data width. data is sent or received in bytes (db7 to db0) when dl = logic 1 or in two nibbles (db7 to db4) when dl = logic 0. when 4-bit width is selected, data is transmitted in two cycles using the parallel bus. in a 4-bit application db3 to db0 should be left open (internal pull-ups). hence in the first function set instruction after power-on n and h are set to logic 1. a second function set must then be sent (2 nibbles) to set n and h to their required values. function set from i 2 c-interface sets the dl bit to logic 1. 9.6.2 m chooses either 1-line by 24 display (m = 0) or 2-line by 12 display (m = 1). 9.6.3 h when h = logic 0 the chip can be programmed via the standard 11 instruction codes used in the pcf2116 and other lcd controllers. when h = logic 1 the extended range of instructions will be used. these are mainly for controlling the display configuration and the icons. 9.7 set cgram address set cgram address sets bits 5 to 0 of the cgram address (a cg in table 6) into the address counter (binary a[5] to a[0]). data can then be written to or read from the cgram. attention: the cgram address uses the same address register as the ddram address and consists of 7 bits (binary a[6] to a[0]). with the set cgram address instruction, only bits 5 down to 0 are set. bit 6 can be set using the set ddram address instruction first, or by using the auto-increment feature during cgram write. all of bits 6 to 0 can be read using the read busy flag and address instruction. when writing to the lower part of the cgram, make sure that bit 6 of the address is not set (e.g. by an earlier ddram write or read action). 1997 apr 04 27 philips semiconductors product speci?cation lcd controller/driver pcf2113x 9.8 set ddram address set ddram address sets the ddram address (a dd in table 6) into the address counter (binary a[6] to a[0]). data can then be written to or read from the ddram. 9.9 read busy ?ag and address read busy flag and address reads the busy flag (bf) and address counter (ac). bf = logic 1 indicates that an internal operation is in progress. the next instruction will not be executed until bf = logic 0, so bf should be checked before sending another instruction. at the same time, the value of the address counter expressed in binary a[6] to a[0] is read out. the address counter is used by both cgram and ddram, and its value is determined by the previous instruction. 9.10 write data to cgram or ddram write data writes binary 8-bit data d[7] to d[0] to the cgram or the ddram. whether the cgram or ddram is to be written into is determined by the previous set cgram address or set ddram address instruction. after writing, the address automatically increments or decrements by 1, in accordance with the entry mode. only bits d[4] to d[0] of cgram data are valid, bits d[7] to d[5] are dont care. 9.11 read data from cgram or ddram read data reads binary 8-bit data d[7] to d[0] from the cgram or ddram. the most recent set address instruction determines whether the cgram or ddram is to be read. the read data instruction gates the content of the data register (dr) to the bus while e is high. after e goes low again, internal operation increments (or decrements) the ac and stores ram data corresponding to the new ac into the dr. note: the only three instructions that update the data register (dr) are: set cgram address set ddram address read data from cgram or ddram. other instructions (e.g. write data, cursor/display shift, clear display, return home) do not modify the data register content. 10 extended function set instructions and features 10.1 new instructions h = logic 1 sets the chip into alternate instruction set mode. 10.2 icon control the pcf2113x can drive up to 120 icons. see fig.17 for cgram to icon mapping. 10.3 im when im = logic 0 the chip is in character mode. in character mode characters and icons are driven (mux 1 : 18). the v lcd generator, if used, produces the v lcd voltage programmed in register v a . when im = logic 1 the chip is in icon mode. in icon mode only the icons are driven (mux 1 : 2) and the v lcd voltage generator, if used, produces the v lcd voltage programmed in register v b . remark: if internally generated v lcd must not be lower than v dd (v dd 4v) 10.4 ib icon blink control is independent of the cursor/character blink function. when ib = logic 0 icon blink is disabled. icon data is stored in cgram character 0 to 2 (3 8 5 = 120 bits for 120 icons). when ib = logic 1 icon blink is enabled. in this case each icon is controlled by two bits. blink consists of two half phases (corresponding to the cursor on and off phases called even and odd phases hereafter). icon states for the even phase are stored in cgram characters 0 to 2 (3 8 5 = 120 bits for 120 icons). these bits also define icon state when icon blink is not used. icon states for the odd phase are stored in cgram character 4 to 6 (another 120 bits for the 120 icons). when icon blink is disabled cgram characters 4 to 6 may be used as normal cgram characters. 1997 apr 04 28 philips semiconductors product speci?cation lcd controller/driver pcf2113x table 9 blink effect for icons and cursor character blink parameter even phase odd phase cursor

the two halves of a split screen are connected in a standard way i.e. column 1/61, 2/62 to 60/120. l = logic 1: the two halves of a split screen are connected in a mirrored way i.e. column 1/120, 2/119 to 60/61. this allows single layer pcb or glass layout. 10.7 display con?guration p, q: default is p, q = logic 0. p = logic 1 mirrors the column data. q = logic 1 mirrors the row data. 10.8 tc1, tc2 default is tc1, tc2 = logic 0. this selects the default temperature coefficient for the internally generated v lcd . tc1,tc2 = 10,01 and 11 selects alternative temperature coefficients 1, 2 and 3 respectively. 10.9 set v lcd v lcd value is programmed by instruction. two on-chip registers hold v lcd values for character mode and icon mode respectively (v a and v b ). the generated v lcd value is independent of v dd , allowing battery operation of the chip. v b must be programmed to ff in character mode (i.e. using v a ) and v a must be programmed to 00 in icon mode. note: if internally generated v lcd must not be lower than v dd . note: im condition v lcd 0 character mode generates v a 1 icon mode generates v b v dd 4v v lcd programming: 1. send function set instruction with h = 1 2. send set v lcd instruction to write to voltage register: a) db7, db6 = 10: db5 to db0 are v lcd of character mode (v a ) b) db7, db6 = 11: db5 to db0 are v lcd of icon mode (v b ) c) db5 to db0 = 000000 switches v lcd generator off (when selected) d) during display off and power-down v lcd generator is also disabled 3. send function set instruction with h = 0 to resume normal programming. 10.10 reducing current consumption reducing current consumption can be achieved by one of the options mentioned in table 10. table 10 reducing current consumption when v lcd lies outside the v dd range and must be generated, it is usually more efficient to use the on-chip generator than an external regulator. table 11 use of the v a and v b registers original mode alternative mode

speci?cation lcd controller/driver pcf2113x 11 interface to microcontroller (parallel interface) the pcf2113x can send data in either two 4-bit operations or one 8-bit operation and can thus interface to 4-bit or 8-bit microcontrollers. in 8-bit mode data is transferred as 8-bit bytes using the 8 data lines db7 to db0. three further control lines e, rs, and r/ w are required. see chapter 7. in 4-bit mode data is transferred in two cycles of 4 bits each using pins db7 to db4 for transaction. the higher order bits (corresponding to db7 to db4 in 8-bit mode) are sent in the first cycle and the lower order bits (db3 to db0 in 8-bit mode) in the second. data transfer is complete after two 4-bit data transfers. note that two cycles are also required for the busy flag check. 4-bit operation is selected by instruction. see figs 14 to 17 for examples of bus protocol. in 4-bit mode pins db3 to db0 must be left open-circuit. they are pulled up to v dd internally. 12 interface to microcontroller (i 2 c-bus interface) 12.1 characteristics of the i 2 c-bus the i 2 c-bus is for bidirectional, two-line communication between different ics or modules. the two lines are a serial data line (sda) and a serial clock line (scl). both lines must be connected to a positive supply via a pull-up resistor. data transfer may be initiated only when the bus is not busy. each byte of eight bits is followed by an acknowledge bit. the acknowledge bit is a high level signal put on the bus by the transmitter during which time the master generates an extra acknowledge related clock pulse. a slave receiver which is addressed must generate an acknowledge after the reception of each byte. also a master receiver must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. the device that acknowledges must pull-down the sda line during the acknowledge clock pulse, so that the sda line is stable low during the high period of the acknowledge related clock pulse (set-up and hold times must be taken into consideration). a master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. in this event the transmitter must leave the data line high to enable the master to generate a stop condition. 12.2 i 2 c-bus protocol before any data is transmitted on the i 2 c-bus, the device which should respond is addressed first. the addressing is always carried out with the first byte transmitted after the start procedure. the i 2 c-bus configuration for the different pcf2113x read and write cycles is shown in figs 23 and 24. the slow down feature of the i 2 c-bus protocol (receiver holds scl low during internal operations) is not used in the pcf2113x. 12.3 de?nitions transmitter: the device which sends the data to the bus receiver: the device which receives the data from the bus master: the device which initiates a transfer, generates clock signals and terminates a transfer slave: the device addressed by a master multi-master: more than one master can attempt to control the bus at the same time without corrupting the message arbitration: procedure to ensure that, if more than one master simultaneously tries to control the bus, only one is allowed to do so and the message is not corrupted synchronization: procedure to synchronize the clock signals of two or more devices. 1997 apr 04 31 philips semiconductors product speci?cation lcd controller/driver pcf2113x mga807 sda scl master transmitter/ receiver master transmitter slave

using internal reset table 13 shows an example of a 1-line display in 8-bit operation. the pcf2113x functions must be set by the function set instruction prior to display. since the ddram can store data for 80 characters, the ram can be used for advertising displays when combined with display shift operation. since the display shift operation changes display position only and ddram contents remain unchanged, display data entered first can be displayed when the return home operation is performed. 18.2 4-bit operation, 1-line display using internal reset the program must set functions prior to 4-bit operation. table 12 shows an example. when power is turned on, 8-bit operation is automatically selected and the pcf2113x attempts to perform the first write as an 8-bit operation. since nothing is connected to db0 to db3, a rewrite is then required. however, since one operation is completed in two accesses of 4-bit operation, a rewrite is required to set the functions (see table 12 step 3). thus, db4 to db7 of the function set are written twice. 18.3 8-bit operation, 2-line display for a 2-line display, the cursor automatically moves from the first to the second line after the 40 th digit of the first line has been written. thus, if there are only 8 characters in the first line, the ddram address must be set after the eighth character is completed (see table 5). note that both lines of the display are always shifted together; data does not shift from one line to the other. 18.4 i 2 c operation, 1-line display a control byte is required with most instructions (see table 16). table 12 4-bit operation, 1-line display example; using internal reset step instruction display operation 1 power supply on (pcf2113x is initialized by the internal reset circuit)

speci?cation lcd controller/driver pcf2113x 21 soldering 21.1 introduction there is no soldering method that is ideal for all ic packages. wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. however, wave soldering is not always suitable for surface mounted ics, or for printed-circuits with high population densities. in these situations reflow soldering is often used. this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our ic package databook (order code 9398 652 90011). 21.2 re?ow soldering reflow soldering techniques are suitable for all lqfp packages. reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several techniques exist for reflowing; for example, thermal conduction by heated belt. dwell times vary between 50 and 300 seconds depending on heating method. typical reflow temperatures range from 215 to 250 c. preheating is necessary to dry the paste and evaporate the binding agent. preheating duration: 45 minutes at 45 c. 21.3 wave soldering wave soldering is not recommended for lqfp packages. this is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices. if wave soldering cannot be avoided, the following conditions must be observed: a double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. the footprint must be at an angle of 45 to the board direction and must incorporate solder thieves downstream and at the side corners. even with these conditions, do not consider wave soldering lqfp packages lqfp48 (sot313-2), lqfp64 (sot314-2) or lqfp80 (sot315-1). during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. maximum permissible solder temperature is 260 c, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 c within 6 seconds. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 21.4 repairing soldered joints fix the component by first soldering two diagonally- opposite end leads. use only a low voltage soldering iron (less than 24 v) applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c. 1997 apr 04 59 philips semiconductors product speci?cation lcd
