PCE85176AUG
4 × 40 LCD segment driver for Chip-On-Glass
Rev. 1 — 12 January 2015
Product data sheet
1. General description
The PCE85176AUG is a peripheral device which interfaces to almost any Liquid Crystal
Display (LCD)1 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).
For a selection of NXP LCD segment drivers, see Table 31 on page 40.
