7. Functional description
The PCA8576C 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 Figure 4 ). It can directly drive any static or multiplexed LCD containing up to four
backplanes and up to 40 segments.
