This document is a Philips Semiconductors product specification of PCF2103 family LCD controllers/drivers. It describes the features, applications, functional description, interface, instructions, etc. of the product in detail.
The PCF2103 family is a low power CMOS LCD controller and driver designed to drive dot matrix LCD displays. It supports 2-line by 12 or 1-line by 24 character formats with 5x8 data format, including support for kana (Japanese syllabary) and user-defined symbols.
The chip provides all necessary functions in a single package, including on-chip generation of LCD bias voltages to minimize external components. It interfaces to microcontrollers via a 4 or 8-bit parallel bus or a 2-wire I²C-bus.
| Display lines and characters | 2-line display of up to 12 characters + 120 icons, or 1-line display of up to 24 characters + 120 icons |
|---|---|
| Character format | 5x7 character format plus cursor; 5 x 8 for kana and user defined symbols |
| Display data RAM capacity | 80 characters |
| Character generator ROM capacity | 240, 5 x 8 characters |
| Logic supply voltage range | 1.8 to 5.5 V |
| Display supply voltage range | 2.2 to 6.5 V |
| LCD outputs | 18 row, 60 column outputs |
The chip supports a 4 or 8-bit parallel bus and a 2-wire I²C-bus interface.
No, the on-chip oscillator requires no external components, though an external clock is also possible.
The chip consumes less than 2.5 pA in power-down mode.
