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 I
2
C-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 (V
DD
, V
SS
and V
LCD
) and suitable
capacitors for decoupling V
LCD
and V
DD
