PCF2119x LCD controllers/drivers Rev. 11 15 July 2013 Product data sheet 1. General description 1 The 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 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 2 microcontrollers via a 4-bit or 8-bit bus or via the 2-wire I C-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. 2. Features and benefits Single-chip LCD controller and driver 2-line display of up to 16 characters plus 160 icons or 1-line display of up to 32 characters plus 160 icons 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 On-chip: Configurable 4, 3, or 2 times voltage multiplier generating LCD supply voltage, independent of V , programmable by instruction (external supply also possible) DD Temperature compensation of on-chip generated V : 0.16 %/K to LCDOUT 0.24 %/K (programmable by instruction) Generation of intermediate LCD bias voltages Oscillator requires no external components (external clock also possible) Display Data RAM (DDRAM): 80 characters Character Generator ROM (CGROM): 240 characters (5 8) Character Generator RAM (CGRAM): 16 characters (5 8); 4 characters used to drive 160 icons, 8 characters used if icon blink feature is used in application 2 4-bit or 8-bit parallel bus and 2-wire I C-bus interface Manufactured in silicon gate CMOS process 18 row and 80 column outputs Multiplex rates 1:18 (2-line display or 1-line display), 1:9 (for 1-line display of up to 16 characters and 80 icons) and 1:2 (for icon only mode) 1.

When only icons are displayed, a much lower LCD operating voltage can be used and the switching frequency of the LCD outputs is reduced; in most applications it is possible to use V as LCD supply voltage DD 3.
