PCA85232U/2DA/Q1,0

LCD 驱动器 LCD DRIVER FOR LOW MULTIPLEX RATES

General description  PCA85232U/2DA/Q1,0

The PCA85232 PCA85232U/2DA/Q1,0 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 easily be cascaded for larger LCD applications. The PCA85232 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).
