9 / 78 page 34COM/60SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD S6A0073 9 PIN DESCRIPTION Pin (No) I/O Name Description Interface VDD(35) for logical circuit (+3V, +5V) VSS1, VSS2 (46, 61) - Power supply 0V (GND) Power Supply V1-V5 (68 - 64) Bias voltage level for LCD driving Vci (58) I Input voltage to the voltage converter to generate LCD drive voltage (Vci = 1.0 to 4.5V). SEG1 - SEG60 (86 -128, 1- 17) O Segment output Segment signal output for LCD drive. LCD COM0 - COM33 (85 - 69, 18 - 34) O Common output Common signal output for LCD drive LCD OSC1, OSC2 (37, 36) I(OSC1), O(OSC2) Oscillator When using internal oscillator, connect external Rf resistor. If external clock is used, connect it to OSC1. External resistor/oscilla tor (OSC1) CLK1, CLK2 (38, 39) O Latch (CLK1)/ Shift (CLK2) clock When EXT = "High", each outputs latch clock and shift clock for extension driver. Extension driver C1, C2 (60, 59) I External capacitance input To use the voltage converter (2 times /3 times), these pins must be connected to the external capacitance. External capacitance M (41) O Alternated signal for LCD driver output When EXT = "High", outputs the alternating signal to convert LCD driver waveform to AC for Extension driver. Extension driver D(40) O Display data interface When EXT = "High", outputs extension driver data (the 61th dot's data) Extension driver EXT(44) I Extension driver control signal When EXT = "High", makes extension driver control signal enable, When EXT = "Low", suppress extra current consumption and CLK1,CLK2,M,D should be open. - RESET (42) I Reset pin Initialized to Low - IE (45) I Selection pin of instruction set. When IE = "High", instruction set is selected as Table 6. When IE = "Low", instruction set is selected as Table 10. - |
