Overview
The PCA85162T/Q900/1,1 is a 32 x 4 automotive LCD driver designed by NXP USA Inc. for low multiplex rates. This peripheral device interfaces with almost any Liquid Crystal Display (LCD) and is capable of generating drive signals for static or multiplexed LCDs containing up to four backplanes and up to 32 segments. It is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus, minimizing communication overhead through features like display RAM with auto-incremented addressing and hardware subaddressing.
