E2C0044-19-96 ¡ Semiconductor ¡ Semiconductor MSM9223 GENERAL DESCRIPTION This version: Sep. 1999 MSM9223 Previous version: Aug. 1999 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. FEATURES • Supply voltage (VDD) • Duplex/Triplex selectable • Applicable VFD tube : 8 to 18.
