PCF2105MU中文资料飞利浦数据手册PDF规格书

GENERAL DESCRIPTION

The PCF2105 integrated circuit is similar to the PCF2114x (described in the “PCF2116 family” data sheet) but does not contain the high voltage generator of that device.

Furthermore, a fast I2C-bus interface (400 kHz) is provided.

The PCF2105 is optimized for chip-on-glass applications.

FEATURES

• Single chip Liquid Crystal Display (LCD) controller/driver

• 1 or 2-line display of up to 24 characters per line, or 2 or 4-line display of up to 12 characters per line

• 5 × 7 character format plus cursor; 5 × 8 for kana (Japanese syllabary) and user-defined symbols

• On-chip generation of intermediate LCD bias voltages

• On-chip oscillator requires no external components (external clock also possible)

• Display data RAM: 80 characters

• Character generator ROM: 240 characters

• Character generator RAM: 16 characters

• 4 or 8-bit parallel bus or 2-wire I2C-bus interface (400 kHz)
