13 / 58 page  Data Sheet S14402EJ1V0DS 11 µµµµPD16682A 3.3 Driver System Pins Pin Symbol Pin Name Pad No. I/O Description SEG0 to SEG131 Segment 126 to 257 Output Segment output pins COM0 to COM63 Common 91 to 122, 260 to 291 Output Common output pins COMS Indicator common 123,292 Output Common output pins for indicator The same signal is output from pin 2. VRS 55,56 These are input pins for the op amp that regulates the LCD driver voltage. Leave the VRS pin open when using the on-chip power supply. VR Op amp inputs 69,70 Input When not using the on-chip power supply, a reference voltage VREG must be input. When using an external power supply, connect the VR pin to a resistor used to regulate the LCD voltage. DUMMY1 to DUMMY8 Dummy pins 1,89,90,124,125, 258,259,293 — Since these pins are not connected to any internal circuits, they should be left open when they are not being used. |
