ML9477 - 1/3 or 1/4 Duty 32-Output LCD Driver

General Description

The ML9477 is an LCD driver for dynamic display.

It has a function to switch between 1/3 and 1/4 duty.

When 1/4 duty is selected, an LCD of up to 128 segments can be driven directly; when 1/3 duty is selected, an LCD of up to 96 segments can be driven directly.

Key Features

  • Logic power supply voltage : 2.7 to 3.6 V, 4.5 to 5.5 V.
  • Driver power supply voltage : 3.5 to 5.5 V.
  • Operatin g temperature : 40 to +105°C.
  • 32 segment outputs 1/4 duty : Up to 128 segments can be displayed. 1/3 duty : Up to 96 segments can be displayed.
  • Serially interfaces with the CPU using the three signal lines of LOAD, DATA_IN, and CLOCK.
  • Built-in RC oscillator circuit for LCD AC drive (the CLKSEL pin allows selecting an external clock input).
  • Built-in v.
