General description

The PCA85232 is a peripheral device which interfaces to almost any Liquid Crystal

Display (LCD)1 with low multiplex rates. It generates the drive signals for any static or

multiplexed LCD containing up to four backplanes and up to 160 segments. It can be

easily cascaded for larger LCD applications. The PCA85232 is compatible with most

microprocessors or microcontrollers and communicates via a two-line bidirectional

I2C-bus. Communication overheads are minimized by a display RAM with

auto-incremented addressing, by hardware subaddressing, and by display memory

switching (static and duplex drive modes).

AEC-Q100 compliant for automotive applications.
