PCF8577C - LCD direct/duplex driver

General Description

The PCF8577C is an LCD driver which drives up to 32 segments directly, or 64 segments in a duplex configuration.

The two-line I2C-bus interface substantially reduces wiring overheads in remote display applications.

Key Features

  • Direct/duplex drive modes with up to 32/64 LCD-segment drive capability per device.
  • Operating supply voltage: 2.5 V to 6 V.
  • Low power consumption.
  • I2C-bus interface.
  • Optimized pinning for single plane wiring.
  • Single-pin built-in oscillator.
  • Auto-increm.

PCF8577C LCD direct/duplex driver with I²C-bus interface Rev. 5 — 10 October 2014 Product data sheet 1. General description The PCF8577C is an LCD driver which drives up to 32 segments directly, or 64 segments in a duplex configuration. The two-line I2C-bus interface substantially reduces wiring overheads in remote display applications. I2C-bus traffic is minimized in multiple IC applications by automatic address incrementing, hardware subaddressing and display memory switching (direct drive mode).To allow partial VDD shutdown, the ESD protection system of the SCL and SDA pins does not use a diode connected to VDD. For a selection of NXP LCD segment drivers, see Table 13 on page 25. 2.
