Open-Drain, and a pull-up resistor on board is needed. SCL I 2-line serial clock input CMOS input, do not need a pull-up resistor. VSS I GND VDD I Power VLCD I Set LCD bias voltage. It can be directly tied to VDD, and then you can adjust the internal LCD bias voltage by setting the registor EV[3:0]. allseg I Seg-Mode selection 1: 96-Seg-Mode; Normal mode. 0: 48-Seg-Mode; Only outward 48 segs can be used, but ITO pitch can be double. This mode is very usefull to reduce the difficulty ot the COG process. S0~S95 O SEGMENT driver output for LCD C0~C3 O MON driver output for LCD March 27, 2020 1/8 .chipnorth.
