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.

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 120μA):

– Icon mode: <25μA

– Power-down mode:

APPLICATIONS

? Telecom equipment

? Portable instruments

? Point-of-sale terminals.
