The PCF8532 is a peripheral device which interfaces to almost any Liquid Crystal Display
(LCD) 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 easily be cascaded
for larger LCD applications. The PCF8532 is compatible with most microcontrollers and
communicates via the two-line bidirectional I²C-bus. Communication overheads are
minimized by a display RAM with auto-incremental addressing, by hardware
subaddressing, and by display memory switching (static and duplex drive modes).
Not to be used for new designs. Replacement part is PCF85132U/2DA/1 for industrial and
PCA85132U/2DA/Q1 for automotive applications.
