This document is the specification sheet of the PCF2103 family LCD controllers/drivers, introducing the features and characteristics of the products in the series.
The PCF2103 family is a low-power CMOS LCD controller and driver designed to drive dot matrix LCD displays of 2 lines by 12 characters or 1 line by 24 characters with a 5x8 dot format. The device integrates all necessary functions for the display, including on-chip generation of LCD bias voltages, which minimizes external components and reduces system current consumption. It interfaces to microcontrollers via a 4 or 8-bit parallel bus or a 2-wire I2C-bus.
| Display capacity | 2-line display of up to 12 characters + 120 icons |
|---|---|
| Character format | 5x7 character format plus cursor |
| Display data RAM | 80 characters |
| Character generator ROM | 240, 5 x 8 characters |
| Logic supply voltage | 1.8 to 5.5 V |
| Display supply voltage | 2.2 to 6.5 V |
| Current consumption (Power-down) | <2.5 pA |
It supports a 2-line display of up to 12 characters plus 120 icons, or a 1-line display of up to 24 characters plus 120 icons.
No, the on-chip oscillator requires no external components, though an external clock is also possible.
The logic supply voltage range is 1.8 to 5.5 V, allowing the chip to be driven with two battery cells.
