PCE85176AUG中文资料4 × 40 LCD segment driver for Chip-On-Glass数据手册恩XP规格书

描述 Description

The PCE85176AUG 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 40 segments. The
PCE85176AUG 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 and by display memory switching (static and duplex
drive modes).
