产品描述

The PCE85133AUG is a peripheral device which interfaces to almost any Liquid CrystalDisplay (LCD) with low multiplex rates. It generates the drive signals for any static ormultiplexed LCD containing up to four backplanes and up to 80 segments. ThePCE85133AUG is compatible with most microcontrollers and communicates via thetwo-line bidirectional I2C-bus. Communication overheads are minimized by a display RAMwith auto-incremental addressing and by display memory switching (static and duplexdrive modes).
