PCA85162 系列 5.5 V 低复用率 通用 LCD 驱动器 - TSSOP-48
Overview
The PCA85162 is a peripheral device which interfaces to almost any Liquid Crystal Display LCD with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 32 segments. It can be easily cascaded for larger LCD applications. The PCA85162 is compatible with most microcontrollers and communicates via the two-line bidirectional I²C-bus. Communication overheads are minimized by a display RAM with auto-incremented addressing, by hardware subaddressing, and by display memory switching static and duplex drive modes.
