PCA85276ATT中文资料低复用率车载LCD驱动器数据手册恩XP规格书

描述 Description

The PCA85276 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 40 segments. It can be easilycascaded for larger LCD applications. The PCA85276 is compatible with mostmicrocontrollers and communicates via the two-line bidirectional I²C-bus. Communicationoverheads are minimized by a display RAM with auto-incremented addressing, byhardware subaddressing, and by display memory switching (static and duplex drivemodes).
