GENERAL DESCRIPTION

The PCF8558 is a low power CMOS LCD controller driver, designed to drive a graphic display of 40 rows and 101 columns. 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 power consumption.

The PCF8558 interfaces to most microcontrollers via a I2C-bus interface.

FEATURES

• Single-chip LCD controller/driver

• 40 row and 101 column outputs

• Display data RAM

40×101 bits = 505 bytes = 4040 bits

• On-chip:

– Generation of intermediate LCD bias voltages

– Oscillator requires no external components(external clock also possible)

• 400 kHz fast I2C-bus interface

• CMOS compatible

• MUX rate 1 : 40

• Logic supply voltage range VDD−VSS= 2.5 to 6 V

• Display supply voltage range VDD−VLCD= 3.5 to 9 V

• Low power consumption, suitable for battery operated systems.
