GENERAL DESCRIPTION
The ML9222 is a full CMOS controller/driver for Duplex or Triplex vacuum
fluorescent display tube. It conststs of 32-segment driver outputs and 3-grid
pre-driver outputs, so that it can drive directly up to 96-segment VFD.
ML9222 features a digital dimming function, a 8-ch ADC, a 5 x 5 keyscan
circuit and an encoder type switch interface.
ML9222 provides an interface with a microcontroller only by four signal lines:
DATA I/O, CLOCK, CS and INT.
FEATURES
• Supply voltage (VDD) : 8 to 18.5V (Built-in 5V regulator for logic)
