27-Bit Duplex/Triplex VFD Controller/Driver with Digital Dimming, ADC and Keyscan
The MSM9223 is a full
CMOS controller/driver for Duplex or Triplex vacuum fluorescent display tube.
It conststs of 27-segment driver outputs and 3-grid pre-driver outputs, so that it can drive directly up to 81-segment VFD.
MSM9223 features a digital dimming function, a 6-ch ADC, a 5 ¥ 5 keyscan circuit and an encoder type switch interface.
MSM9223 provides an interface with a microcontroller only by three signal lines: DATA I/O, CLOCK and CS.
