PCE85133AUG/DAZ

LCD DRVR 1DIGIT 1.8V to 5.5V 110Pin DIE Waffle Pack

Overview

The PCE85133AUG 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 80 segments. The PCE85133AUG is compatible with most microcontrollers and communicates via the two-line bidirectional I²C-bus. Communication overheads are minimized by a display RAM with auto-incremental addressing and by display memory switching static and duplex drive modes.
