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)

battery cells)
LCD supply voltage: V V = 2.2 V to 6.5 V

V V =2.2Vto4V
DD3 SS2
Direct mode to save current consumption for icon mode and multiplex drive mode 1:9
(depending on V value and LCD liquid properties)
DD2
Very low current consumption (20 A to 200 A):
Icon mode: < 25 A
Power-down mode: < 2 A
Icon mode is used to save current. 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
