VFD CONTROLLER / DRIVER

SOP-28-375-1.27

DESCRIPTION

SC16313 is a Vacuum Fluorescent Display (VFD) or Fluorescent

Indicator Panel (FIP) controller/driver that is driven on a 1/4 to 1/8 duty

factor. It consists of 8 segment output lines, 4 grid output lines, 4

segment/grid output lines, one display memory, control circuit, key

scan circuit. Serial data is input to SC16313 via a three-line serial

interface. This VFD driver is ideal as a peripheral device of a single-

chip microcomputer.

FEATURES

* CMOS technology

* High-voltage output

* Key scanning (8 x 2 matrix)

* Multiple display modes: (8 segments & 8 digits to 12 segments & 4

digits)

* 8-step dimming circuitry

* Serial interface (CLK, DIN, DOUT, STB)

* No external resistors needed for driver outputs
