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.
2. Features and benefits
Single chip LCD controller and driver
Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing
Selectable display bias configuration: static, 12, or 13
Internal LCD bias generation with voltage-follower buffers
40 segment drives:
Up to 20 7-segment alphanumeric characters
Up to 10 14-segment alphanumeric characters
Any graphics of up to 160 elements
40 4-bit RAM for display data storage
Display memory bank switching in static and duplex drive modes
Versatile blinking modes
Independent supplies possible for LCD and logic voltages
Wide power supply range: from 1.8 V to 5.5 V
Wide logic LCD supply range:
From 2.5 V for low-threshold LCDs
Up to 5.5 V for high-threshold twisted nematic LCDs
Low power consumption
400 kHz I2C-bus interface
No external components required
Compatible with Chip-On-Glass (COG) technology
