Oki Electric Industry MSM9223
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 provides an interface with a microcontroller only by three signal lines: DATA I/O, CLOCK and CS.| Part No. | MSM9223 |
