The PCF8566 is a versatile peripheral device designed to interface any
microprocessor or microcontroller to a wide variety of LCDs. It can directly drive any static
or multiplexed LCD containing up to 4 backplanes and up to 24 segments.
The display configurations possible with the PCF8566 depend on the number of active
backplane outputs required. Display configuration selection is shown in
display configurations given in
Figure
The host microprocessor or microcontroller maintains the 2-line I
channel with the PCF8566.
Biasing voltages for the multiplexed LCD waveforms are generated internally, removing
the need for an external bias generator. The internal oscillator is selected by connecting
pin OSC to V
power supplies (pins V
