PCF8535

FUNCTIONAL DESCRIPTION

The PCF8535 is a low power LCD driver designed to interface with microprocessors/microcontrollers and a wide variety

of LCDs.

The host microprocessor/microcontroller and the PCF8535 are both connected to the I2C-bus. The SDA and SCL lines

must be connected to the positive power supply via pull-up resistors. The internal oscillator requires no external

components. The appropriate intermediate biasing voltage for the multiplexed LCD waveforms are generated on-chip.

The only other connections required to complete the system are to the power supplies (VDD,VSS and VLCD) and suitable

capacitors for decoupling VLCD and VDD.
