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 VLCD,

independent of VDD, programmable by instruction (external supply also possible)

N Temperature compensation of on-chip generated VLCD: −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)

I Display data RAM: 80 characters

I Character generator ROM: 240 characters of 5 × 8 dots

I Character generator RAM: 16 characters of 5 × 8 dots; 3 characters used to drive

120 icons, 6 characters used if icon blink feature is used in application

I 4-bit or 8-bit parallel bus and 2-wire I2C-bus interface

I 18 row and 60 column outputs
