Product data sheet
1. General description
The PCF2113x is a low-power CMOS LCD controller and driver, designed to drive a dot
matrix LCD display of 2 lines of 12 characters or 1 line of 24 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 PCF2113x 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 PCF2113x characterizes the built-in character set. Various character sets
can be manufactured on request.
2. Features
I Single-chip LCD controller/driver
I 2-line display of up to 12 characters + 120 icons, or 1-line display of up to
24 characters + 120 icons
I 5 × 7 character format plus cursor; 5 × 8 for kana (Japanese) and user-defined
symbols
I Icon mode for e.g. additional segment display section: reduced current consumption
while displaying icons only
I Icon blink function
I Very low current consumption (20 µA to 200 µA):
N Icon mode: < 25 µA
N Power-down mode: < 2 µA
I On-chip:
N Configurable 4, 3 or 2 voltage multiplier, generating LCD supply voltage V_LCD,
independent of V_DD, programmable by instruction (external supply also possible)
N Temperature compensation of on-chip generated V_LCD: −0.16 %/K to −0.24 %/K
(programmable by instruction)
N Generation of intermediate LCD bias voltages
N Oscillator requires no external components (external clock also possible)
