PCF8532U Universal LCD driver for low multiplex rates
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
