The PCF8576 is a versatile peripheral device designed to
interface to any microprocessor/microcontroller to a wide
variety of LCDs. It can directly drive any static or
multiplexed LCD containing up to four backplanes and up
to 40 segments. The display configurations possible with
the PCF8576 depend on the number of active backplane
outputs required; a selection of display configurations is
given in Table .
All of the display configurations given in Table can be
implemented in the typical system shown in Fig.3.
