LCD driver for low multiplex rates

7. Functional description

The PCF85132 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 160 segments.

The display configurations possible with the PCF85132 depend on the required number of

active backplane outputs. A selection of display configurations is given in Table 4.

All of the display configurations given in Table 4 can be implemented in a typical system

as shown in Figure 4.
