PCF8576C
Product data sheet
The PCF8576C is a versatile peripheral device designed to interface between any
microprocessor or microcontroller to a wide variety of LCD segment or dot matrix displays
(see
backplanes and up to 40 segments.
The possible display configurations of the PCF8576C depend on the number of active
backplane outputs required. A selection of display configurations is shown in
of these configurations can be implemented in the typical system shown in
