ML9212 - 32-Bit Duplex/Triplex (1/2 duty / 1/3 duty) VF Controller/Driver

General Description

The ML9212 is a full CMOS controller/driver for Duplex or Triplex (1/2 duty or 1/3 duty) vacuum fluorescent display tube.

It consists of a 32-segment driver multiplexed to drive up to 96 segments, and 10-bit digital dimming circuit.

Key Features

  • a selection of a master mode and a slave mode, and therefore it can be used to expand segments for the VFD driver with keyscan and A/D converter function. ML9212 provides an interface with a microcontroller only by three signal lines: DATA IN, CLOCK and CS.
