6 / 44 page  Data Sheet S12694EJ2V0DS00 6 µµµµPD16680 3. PIN DESCRIPTIONS 3.1 Power System Pins Pin Symbol Pin Name Pin No. I/O Function Description VDD Logic and booster power supply pin 22, 23, 48 to 50, 73 to 75, 82, 96 - Power supply pin for logic and booster circuit. VSS Logic and driver ground pin 51 to 53 - Ground pin for logic and driver circuit. VLCD Driver power supply pin 45 to 47 - Driver power supply pin. Output pin of internal booster circuit. Please connect with a 1 µF booster capacitor to ground. When not using the internal booster circuit, the driver power can be turned on directly. VLC1 to VLC5 Driver reference power supply 25 to 27, 29 to 31, 33 to 35, 37 to 39, 41 to 43 - Reference power supply pin for LCD drive. When the internal bias is selected, be sure to leave it open. When display contrast is bad, connect a capacitor between these pins and ground. VLCBS1 to VLCBS3 Bias level select pin 4, 5, 7, 8, 10, 11 - When the internal bias is selected, Connecting these pins outside the IC, the bias level can be changed. C1 +, C 1 – C2 +, C 2 – C3 +, C 3 – Capacitor connection pins 55 to 72 - Capacitor connection pins for booster circuit. When using internal booster circuit, connect a 1 µF capacitor between these pins. 5 |
