PCF8577 - LCD direct/duplex driver

General Description

The PCF8577 is a single chip, silicon gate CMOS circuit.

It is designed to drive liquid crystal displays with up to 32 segments directly, or 64 segments in a duplex manner.

The two-line 12 Cbus interface substantially reduces wiring overheads in remote display applications.

Key Features

  • Direct/duplex drive modes with up to 32/64 LCD-segment drive capabilitv per device.
  • Operating supply voltage: 2.5 to 9 V.
  • Low power consumption.
  • 12 C-bus interface.
  • Optimized pinning for single plane wiring.
  • Single-pin built-in oscillator.
  • Auto-incremented loadin.

PCF8577 PCF8577A LCD DIRECTIDUPLEX DRIVER WITH 12C-BUS INTERFACE GENERAL DESCRIPTION The PCF8577 is a single chip, silicon gate CMOS circuit. It is designed to drive liquid crystal displays with up to 32 segments directly, or 64 segments in a duplex manner. The two-line 12 Cbus interface substantially reduces wiring overheads in remote display applications. Bus traffic is minimized in multiple IC applications by automatic address incrementing, hardware subaddressing and display memory switching (direct drive mode). The PCF8577 and PCF8577 A differ only in their slave addresses.
