PCF2119x chip contains a character generator and display alphanumeric and kana (Japanese) characters. Its interfaces to most microcontrollers via a 4-bit or 8-bit bus or via the 2-wire I²C-bus.
PCF2119x is a low power CMOS LCD controller and driver, designed to drive a dot matrix LCD display of 2-lines by 16 characters or 1-line by 32 characters with 5 x 8 dot format. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD bias voltages, resulting in a minimum of external components and lower system current consumption.
The letter ‘x’ in PCF2119x characterizes the built-in character set. Various character sets can be manufactured on request. In addition 16 user defined symbols (5 × 8 dot format) are available.
- 5 × 7 character format plus cursor; 5 × 8 for kana (Japanese) and user defined symbols
- Reduced current consumption while displaying icons only
- Icon blink function
- Single-chip LCD controller and driver
- 18 row and 80 column outputs
- Point-of-sale terminals
- Telecom equipment
- Portable instruments
