PCE85176AUG - 4 x 40 LCD segment driver

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.

Key Features

  • Single chip LCD controller and driver.
  • Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing.
  • Selectable display bias configuration: static, 1⁄2, or 1⁄3.
  • 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.

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.
