简单介绍
The PCF8576C is a peripheral device which interfaces to almost any Liquid CrystalDisplay (LCD)1 with low multiplex rates. It generates the drive signals for any static ormultiplexed LCD containing up to four backplanes and up to 40 segments and can easilybe cascaded for larger LCD applications. The PCF8576C is compatible with mostmicroprocessors or microcontrollers and communicates via a two-line bidirectionalI2C-bus. Communication overheads are minimized by a display RAM withauto-incremented addressing, by hardware subaddressing
