PCF85132 - LCD driver

General Description

The PCF85132 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 160 segments.

It can easily be cascaded for larger LCD applications.

Key Features

  • Single-chip LCD controller and driver for up to 640 elements.
  • Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing.
  • 160 segment drives:.
  • Up to 80 7-segment numeric characters.
  • Up to 40 14-segment alphanumeric characters.
  • Any graphics of up to 640 elements.
  • May be cascaded for large LCD.

PCF85132 LCD driver for low multiplex rates Rev. 4 — 24 April 2015 Product data sheet 1. General description The PCF85132 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 160 segments. It can easily be cascaded for larger LCD applications. The PCF85132 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, by hardware subaddressing, and by display memory switching (static and duplex drive modes). For a selection of NXP LCD segment drivers, see Table 29 on page 56. 2.
