SC16313

SC16313 VFD CONTROLLER / DRIVER 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 singlechip microcomputer. SOP-28-375-1.27 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 * Microcomputer peripheral device.
