Manufacturer: Description:Power supply: 3V /5V LCD driving voltage VLCD V1 V2 VSS, VLCD VDD Bias At 1/3 bias ratio, keep V1- V2 open At 1/2 bias ratio, short V1- V2 GND VSS =0V Display OFF When INHb is "H", display is ON, and when INHb is "L", display is off. When INHb is L", all segment and common drivers output VSS, and the oscillator stop operation. But, if at the same time RSTb="L", the oscillator functions and all segment and common drivers output VSS Reset When RSTb is L", command register and latch circuit is reset Chip select When CSb is "L", data can be read in. Serial data input (8 bit=1word) Serial clock External resistor connection pin for CR oscillation, or external clock input pin. When external clock is used, input the signal to OSC1 and keep OSC2 open. Common driver outputs Segment driver outputs Segment driver outputs/general purpose output ports These 4 pins can be used as segment driver outputs or general purpose output ports by setting Command Register. When selected as general purpose ports, data can be outputted via these ports during COM1 timing. According to transferred data, "H"=VDD or "L"=VSS will be outputted. |
