PCA85176
40 x 4 automotive LCD driver for low multiplex rates
7. Functional description
The PCA85176 is a versatile peripheral device designed to interface between any
microcontroller to a wide variety of LCD segment or dot matrix displays. It can directly
drive any static or multiplexed LCD containing up to four backplanes and up to
40 segments.

Table 11
All available commands carry a continuation bit C in their most significant bit position as
shown in Figure 22. When this bit is set logic 1, it indicates that the next byte of the
transfer to arrive will also represent a command. If this bit is set logic 0, it indicates that
the command byte is the last in the transfer. Further bytes will be regarded as display data
(see Table 6).
