11812hkpc 20110826-s00008 no.a1976-1/43 http://onsemi.com semiconductor components industries, llc, 2013 july, 2013 LC75809PT overview the LC75809PT is the 1/4 duty and 1/3 duty general-purpose microprocessor-controlled lcd driver that can be used in applications such as frequency display in products with electronic tuning. in addition to being able to drive up to 352 segments directly, the LC75809PT can also control up to 12 general-purpose output ports. because it has the pwm output of a maximum of 6ch, the brightness control of the led backlight of rgb 2 can be done. incorporation of an oscillation circuit helps to reduce the number of external resistors and capacitors required. features ? support for 1/4-duty 1/3-bias or 1/3-duty 1/3-bias drive techniques under serial data control. when 1/4-duty : capable of driving up to 352 segments when 1/3-duty : capable of driving up to 267 segments ? serial data input supports ccb format communication with the system controller. (support 3.3v and 5v operation) ? serial data control of the power-saving mode based backup function and the all segments forced off function. ? serial data control of switching between the segment output port and general-purpose output port function. (support for up to 12 general-purpose output ports) ? support for the pwm output function of a maximum of 6ch. (it can output from the general-purpose output port). ? support for clock output function of 1ch. (it can output from the general-purpose output port). ? serial data control of the frame frequency of the common and segment output waveforms. ? serial data control of switching between the internal oscillator operating mode and external clock operating mode. ? high generality, since display data is displayed directly without the intervention of a decoder circuit. ? built-in display contrast adjustment circuit. ? the inh pin allows the display to be forced to the off state. ? incorporation of an oscillator circuit. (incorporation of resistor and capacitor for an oscillation) ordering number : ena1976 cmos ic 1/4 and 1/3-duty general-purpose lcd display driver ? ccb is on semiconductor? ?s original format. all addresses are managed by on semiconductor? for this format. ? ccb is a registered trademark of semiconductor components industries, llc.

LC75809PT no.a1976-41/43 notes on controller transf er of display data when using the LC75809PT in 1/4 duty, applications transfer the display data (d1 to d352) in four operations, and in 1/3 duty, they transfer the display data (d1 to d267) in three operations. in either case, applications should transfer all of the display data within 30 ms to maintain the quality of displayed image. s89/osci pin peripheral circuit (1) internal oscillator operating mode (control data oc=0) connect the s89/osci pin to the lcd panel when the internal oscillator operating mode is selected. (2) external clock operating mode (control data oc=1) when the external clock operating m ode is selected, insert a current pr otection resistor rg (2.2 to 22k ) between the s89/osci pin and external clock output pin (external oscillator). determine the value of the resistance according to the allowable current value at the ex ternal clock output pin. also make sure that the waveform of the external clock is not heavily distorted. (3) unused pin treatment when the s89/osci pin is not to be used, select the intern al oscillator operating mode (setting control data oc to 0) to keep the pin open. p1 to p12 pin peripheral circuit it is recommended the circuit shown below be used to adjust the brightness of the led backlight using the pwm output p1 to p12 osci/s89 external clock output pin rg external oscillato r note : allowable current value at external clock output pin > v dd rg osci/s89 to lcd panel osci/s89 open p1 to p12 led +5v
