Universal LCD driver for low multiplex rates

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 3). It can directly drive any static or multiplexed LCD containing up to four

backplanes and up to 40 segments.

Fig 3. Example of displays suitable for PCA8576C

The possible display configurations of the PCA8576C depend on the number of active

backplane outputs required. A selection of display configurations is shown in Table 4. All

of these configurations can be implemented in the typical system shown in Figure 4.
