APPLICATIONS

• Telecom equipment

• Portable instruments

• Point-of-sale terminals.

GENERAL DESCRIPTION

The PCF2103 family is a low power CMOS LCD controller

and driver, designed to drive a dot matrix LCD display of

2 line by 12 or 1 line by 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 PCF2103

interfaces to most microcontrollers via a 4 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 PCF2103X

characterizes the built-in character set. Various character

sets can be manufactured on request.

FEATURES

• Single-chip LCD controller/driver

• 2-line display of up to 12 characters + 120 icons,

or 1-line display of up to 24 characters + 120 icons

• 5 × 7 character format plus cursor; 5 × 8 for kana

(Japanese syllabary) and user defined symbols

• Icon mode: reduced current consumption while

displaying icons only(1)

• Icon blink function

• On-chip:

– Generation of intermediate LCD bias voltages

– Oscillator requires no external components

(external clock also possible)

• Display data RAM: 80 characters

• Character generator ROM: 240, 5 × 8 characters

• Character generator RAM: 16, 5 × 8 characters;

3 characters used to drive 120 icons, 6 characters used

if icon blink feature is used in application

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

• CMOS compatible

• 18 row, 60 column outputs

• Mux rates 1 : 18 (for normal operation) and 1 : 2

(for icon-only mode)

• Uses common 11 code instruction set (extended)

• Logic supply voltage range, VDD − VSS = 1.8 to 5.5 V;

chip may be driven with two battery cells

• Display supply voltage range, VLCD − VSS = 2.2 to 6.5 V

• Very low current consumption (20 to 120 µA):

– Icon mode: <25

µA

– Power-down mode: <2.5

µA.

(1)

Icon mode is used to save current. When only icons

are displayed, a much lower operating voltage VLCD

can be used and the switching frequency of the LCD

outputs is reduced. In most applications it is possible

to use VDD as VLCD.
