FUNCTIONAL DESCRIPTION
The PCF8566 is a versatile peripheral device designed to
interface any microprocessor 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; a selection of display configurations is given in
Table 1.
All of the display configurations given in Table 1 can be
implemented in the typical system shown in Fig.3.
The host microprocessor/microcontroller maintains the
two-line I
2
C-bus communication channel with the
PCF8566. The internal oscillator is selected by tying OSC
(pin 6) to V
SS
. The appropriate biasing voltages for the
multiplexed LCD waveforms are generated internally.
The only other connections required to complete the
system are to the power supplies (V
DD
, V
SS
and V
LCD
) and
to the LCD panel chosen for the application.
