1. General description
The PCF2119x is a low power CMOS¹ 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 × 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 PCF2119x interfaces to most
microcontrollers via a 4-bit or 8-bit bus or via the 2-wire I²C-bus. The chip contains a
character generator and displays alphanumeric and kana (Japanese) characters.
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.
