PCF2103中文资料飞利浦数据手册PDF规格书

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.
