PCF8534A
Universal LCD driver for low multiplex rates
7. Functional description
The PCF8534A is a versatile peripheral device designed to interface between any
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
60 segments.
The display configurations possible with the PCF8534A 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 5 .
