87C654
DESCRIPTION
The 87C654 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 87C654 has the same instruction set as the 80C51. Two versions of the derivative exist: 83C654--16k bytes mask programmable ROM 87C654--EPROM version This device provides architectural enhancements that make it applicable in a variety of applications for general control systems. The 87C654 contains a non-volatile 16k x 8 EPROM, a volatile 256 x 8 read/write data memory, four 8-bit I/O ports, two 16-bit timer/event counters (identical to the timers of the 80C51), a multi-source, two-priority-level, nested interrupt structure, an I2C interface, UART and on-chip oscillator and timing circuits. For systems that require extra capability, the 87C654 can be expanded using standard TTL compatible memories and logic. The device also functions as an arithmetic processor having facilities for both binary and BCD arithmetic plus bit-handling capabilities. The instruction set consists of over 100 instructions: 49 one-byte, 45 two-byte and 17 three-byte. With a 16MHz crystal, 58% of the instructions are executed in 0.75s and 40% in 1.5s. Multiply and divide instructions require 3s.

PIN NUMBER MNEMONIC VSS VCC P0.0-0.7 DIP 20 40 39-32 LCC 22 44 43-36 QFP 16 38 37-30 TYPE I I I/O NAME AND FUNCTION Ground: 0V reference. Power Supply: This is the power supply voltage for normal, idle, and power-down operation. Port 0: Port 0 is an open-drain, bidirectional I/O port. Port 0 pins that have 1s written to them float and can be used as high-impedance inputs. Port 0 is also the multiplexed low-order address and data bus during accesses to external program and data memory. In this application, it uses strong internal pull-ups when emitting 1s. Port 0 also outputs the code bytes during program verification in the 87C654. External pull-ups are required during program verification. Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull-ups, except P1.6 and P1.7 which are open drain. Port 1 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 1 pins that are externally pulled low will source current because of the internal pull-ups. (See DC Electrical Characteristics: IIL). Port 1 also receives the low-order address byte during program memory verification. Alternate functions include: SCL: I2C-bus serial port clock line. SDA: I2C-bus serial port data line. Port 2: Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. Port 2 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 2 pins that are externally being pulled low will source current because of the internal pull-ups. (See DC Electrical Characteristics: IIL). Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory that use 16-bit addresses (MOVX @DPTR). In this application, it uses strong internal pull-ups when emitting 1s. During accesses to external data memory that use 8-bit addresses (MOV @Ri), port 2 emits the contents of the P2 special function register. Port 3: Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 3 pins that are externally being pulled low will source current because of the pull-ups. (See DC Electrical Characteristics: IIL). Port 3 also serves the special features of the 80C51 family, as listed below: RxD (P3.0): Serial input port TxD (P3.1): Serial output port INT0 (P3.2): External interrupt INT1 (P3.3): External interrupt T0 (P3.4): Timer 0 external input T1 (P3.5): Timer 1 external input WR (P3.6): External data memory write strobe RD (P3.7): External data memory read strobe Reset: A high on this pin for two machine cycles while the oscillator is running, resets the device. An internal diffused resistor to VSS permits a power-on reset using only an external capacitor to VCC. Address Latch Enable/Program Pulse: Output pulse for latching the low byte of the address during an access to external memory. In normal operation, ALE is emitted at a constant rate of 1/6 the oscillator frequency, and can be used for external timing or clocking. Note that one ALE pulse is skipped during each access to external data memory. This pin is also the program pulse input (PROG) during EPROM programming. Program Store Enable: The read strobe to external program memory. When the 87C654 is executing code from the external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external data memory. PSEN is not activated during fetches from internal program memory. External Access Enable/Programming Supply Voltage: EA must be externally held low to enable the device to fetch code from external program memory locations 0000H and 3FFFH. If EA is held high, the device executes from internal program memory unless the program counter contains an address greater than 3FFFH. This pin also receives the 12.75V programming supply voltage (VPP) during EPROM programming. Crystal 1: Input to the inverting oscillator amplifier and input to the internal clock generator circuits.

OSCILLATOR CHARACTERISTICS
XTAL1 and XTAL2 are the input and output, respectively, of an inverting amplifier. The pins can be configured for use as an on-chip oscillator, as shown in the Logic Symbol. To drive the device from an external clock source, XTAL1 should be driven while XTAL2 is left unconnected. There are no requirements on the duty cycle of the external clock signal, because the input to the internal clock circuitry is through a divide-by-two flip-flop. However, minimum and maximum high and low times specified in the data sheet must be observed.
milliseconds) plus two machine cycles. At power-on, the voltage on VCC and RST must come up at the same time for a proper start-up.
Idle Mode
In the idle mode, the CPU puts itself to sleep while all of the on-chip peripherals stay active. The instruction to invoke the idle mode is the last instruction executed in the normal operating mode before the idle mode is activated. The CPU contents, the on-chip RAM, and all of the special function registers remain intact during this mode. The idle mode can be terminated either by any enabled interrupt (at which time the process is picked up at the interrupt service routine and continued), or by a hardware reset which starts the processor in the same manner as a power-on reset.
power-down is the last instruction executed. Only the contents of the on-chip RAM are preserved. A hardware reset is the only way to terminate the power-down mode. The control bits for the reduced power modes are in the special function register PCON. Table 2 shows the state of the I/O ports during low current operating modes.
I2C SERIAL COMMUNICATION--SIO1
The I2C serial port is identical to the I2C serial port on the 8XC552. The operation of this subsystem is described in detail in the 8XC552 section of this manual. Note that in both the 8XC652/4 and the 8XC552 the I2C pins are alternate functions to port pins P1.6 and P1.7. Because of this, P1.6 and P1.7 on these parts do not have a pull-up structure as found on the 80C51. Therefore P1.6 and P1.7 have open drain outputs on the 8XC652/4.
Reset
A reset is accomplished by holding the RST pin high for at least two machine cycles (24 oscillator periods), while the oscillator is running. To insure a good power-on reset, the RST pin must be high long enough to allow the oscillator time to start up (normally a few
Power-Down Mode
In the power-down mode, the oscillator is stopped and the instruction to invoke

NOTES FOR DC ELECTRICAL CHARACTERISTICS: 1. The input threshold voltage of P1.6 and P1.7 (SIO1) meets the I2C specification, so an input voltage below 0.3VCC will be recognized as a logic 0 while an input voltage above 0.7VCC will be recognized as a logic 1. 2. Capacitive loading on ports 0 and 2 may cause spurious noise to be superimposed on the VOLs of ALE and ports 1 and 3. The noise is due to external bus capacitance discharging into the port 0 and port 2 pins when these pins make 1-to-0 transitions during bus operations. In the worst cases (capacitive loading > 100pF), the noise pulse on the ALE pin may exceed 0.8V. In such cases, it may be desirable to qualify ALE with a Schmitt Trigger, or use an address latch with a Schmitt Trigger STROBE input. IOL can exceed these conditions provided that no single output sinks more than 5mA and no more than two outputs exceed the test conditions. 3. Under steady state (non-transient) conditions, IOL must be externally limited as follows: Maximum IOL = 10mA per port pin; Maximum IOL = 26mA total for Port 0; Maximum IOL = 15mA total for Ports 1, 2, and 3; Maximum IOL = 71mA total for all output pins. If IOL exceeds the test conditions, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test conditions. 4. Capacitive loading on ports 0 and 2 may cause the VOH on ALE and PSEN to momentarily fall below the 0.9VCC specification when the address bits are stabilizing. 5. Pins of ports 1 , 2, and 3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches its maximum value when VIN is approximately 2V. 6. See Figures 9 through 11 for ICC test conditions. 7. The operating supply current is measured with all output pins disconnected; XTAL1 driven with tr = tf = 10ns; VIL = VSS + 0.5V; VIH = VCC -0.5V; XTAL2 not connected; EA = RST = Port 0 = P1.6 = P1.7 = VCC; fCLK = 16MHz. See Figure 9. 8. The idle mode supply current is measured with all output pins disconnected; XTAL1 driven with tr = tf = 10ns; VIL = VSS + 0.5V; VIH = VCC -0.5V; XTAL2 not connected; Port 0 = P1.6 = P1.7 = VCC; EA = RST = VSS; fCLK = 16MHz. See Figure 10. 9. The power-down current is measured with all output pins disconnected; XTAL2 not connected; Port 0 = P1.6 = P1.7 = VCC; EA = RST = VSS. See Figure 11. 10. 2V VPD VCCmax.

EPROM CHARACTERISTICS
The 87C654 is programmed by using a modified Quick-Pulse ProgrammingTM algorithm. It differs from older methods in the value used for VPP (programming supply voltage) and in the width and number of the ALE/PROG pulses. The 87C654 contains two signature bytes that can be read and used by an EPROM programming system to identify the device. The signature bytes identify the device as an 87C654 manufactured by Philips Components. Table 4 shows the logic levels for reading the signature byte, and for programming the program memory, the encryption table, and the lock bits. The circuit configuration and waveforms for quick-pulse programming are shown in Figures 12 and 13. Figure 14 shows the circuit configuration for normal program memory verification.
To program the encryption table, repeat the 25 pulse programming sequence for addresses 0 through 1FH, using the `Pgm Encryption Table' levels. Do not forget that after the encryption table is programmed, verification cycles will produce only encrypted data. To program the lock bits, repeat the 25 pulse programming sequence using the `Pgm Lock Bit' levels. After one lock bit is programmed, further programming of the code memory and encryption table is disabled. However, the other lock bit can still be programmed. Note that the EA/VPP pin must not be allowed to go above the maximum specified VPP level for any amount of time. Even a narrow glitch above that voltage can cause permanent damage to the device. The VPP source should be well regulated and free of glitches and overshoot. Program Verification If lock bit 2 has not been programmed, the on-chip program memory can be read out for program verification. The address of the program memory locations to be read is applied to ports 1 and 2 as shown in Figure 14. The other pins are held at the `Verify Code Data' levels indicated in Table 4. The contents of the address location will be emitted on port 0. External pull-ups are required on port 0 for this operation. If the encryption table has been programmed, the data presented at port 0 will be the exclusive NOR of the program byte with one of the encryption bytes. The user will have to know the encryption table contents in order to correctly decode the verification data. The encryption table itself cannot be read out.
Reading the Signature Bytes The signature bytes are read by the same procedure as a normal verification of locations 030H and 031H, except that P3.6 and P3.7 need to be pulled to a logic low. The values are: (030H) = 15H indicates manufactured by Philips (031H) = 99H indicates 87C654
Program/Verify Algorithms
Any algorithm in agreement with the conditions listed in Table 4, and which satisfies the timing specifications, is suitable.
Erasure Characteristics
Erasure of the EPROM begins to occur when the chip is exposed to light with wavelengths shorter than approximately 4,000 angstroms. Since sunlight and fluorescent lighting have wavelengths in this range, exposure to these light sources over an extended time (about 1 week in sunlight, or 3 years in room level fluorescent lighting) could cause inadvertent erasure. For this and secondary effects, it is recommended that an opaque label be placed over the window. For elevated temperature or environments where solvents are being used, apply Kapton tape Fluorglas part number 2345-5, or equivalent. The recommended erasure procedure is exposure to ultraviolet light (at 2537 angstroms) to an integrated dose of at least 15W-sec/cm2. Exposing the EPROM to an ultraviolet lamp of 12,000W/cm2 rating for 20 to 39 minutes, at a distance of about 1 inch, should be sufficient. Erasure leaves the array in an all 1s state.
Quick-Pulse Programming
The setup for microcontroller quick-pulse programming is shown in Figure 12. Note that the 87C654 is running with a 4 to 6MHz oscillator. The reason the oscillator needs to be running is that the device is executing internal address and program data transfers. The address of the EPROM location to be programmed is applied to ports 1 and 2, as shown in Figure 12. The code byte to be programmed into that location is applied to port 0. RST, PSEN and pins of ports 2 and 3 specified in Table 4 are held at the `Program Code Data' levels indicated in Table 4. The ALE/PROG is pulsed low 25 times as shown in Figure 13.
