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.

A specific letter code ‘M’ for a character set is programmed

in the Character Generator ROM (CGROM) (see Fig.5).

The PCF2105 is a low power CMOS LCD controller/driver,

designed to drive a split screen dot matrix LCD of

1 or 2 lines by 24 characters or 2 or 4 lines by

12 characters with a 5

× 8 dot format. All necessary

functions for the display are provided in a single chip,

including on-chip generation of LCD bias voltages which

results in a minimum of external components and lower

system power consumption. To allow partial VDD shutdown

the ESD protection system of the SCL and SDA pads does

not use a diode connected to VDD.

The chip contains a character generator and displays

alphanumeric and kana characters. The PCF2105

interfaces to most microcontrollers via a 4 or 8-bit parallel

bus, or via the 2-wire I2C-bus.
