3.2.1 General Description
3.2 Character Driver PCF2119
The PCF2119x is a low power CMOS LCD controller and driver, designed to drive a dot
matrix LCD display of 2-line by 16 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
temperature compensated 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 or 8-bit bus or via the 2-wire I
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. The character set of the PCF2119 on the demo board is ‘S’.
A similar device is the PCF2113 (2-line by 12 or 1-line by 24 characters + 120 icons).
