Features & Applications

The PCF8579HT/1 is a low power CMOS LCD column driver, designed to drive dot matrix graphic displays at multiplex rates of 1:8, 1:16, 1:24 or 1:32. The device has 40 outputs and can drive 32 x 40 dots in a 32 row multiplexed LCD.

It is compatible with most microcontrollers and communicates via a two-line bidirectional bus (I²C-bus).  Communication overhead is minimized by a display RAM with auto-incremented addressing and display bank switching.

Features and benefits:

  • LCD column driver
  • Used in conjunction with the PCF8578, this device forms part of a chip set capable of driving up to 40960 dots
  • 40 column outputs
  • Externally selectable bias configuration, 5 or 6 levels
  • Easily cascadable for large applications (up to 32 devices)
  • 1280-bit RAM for display data storage
  • Display memory bank switching
  • Auto-incremented data loading across hardware subaddress boundaries (with PCF8578)
  • Power-On Reset (POR) blanks display
  • Logic voltage supply range 2.5 V to 6 V
  • Maximum LCD supply voltage 9 V
  • Low power consumption
  • I²C-bus interface
  • Space saving 56-lead small outline package and 64-pin quad flat pack

Applications:

  • Automotive information systems
  • Telecommunication systems
