uPD16312 Product details

Description

The µPD16312 is a FIP (Fluorescent Indicator Panel, or Vacuum Fluorescent Display) controller/driver that is driven on a 1/4- to 1/11- duty factor.It consists of 11 segment output lines, 6 grid output lines, 5 segment/grid output drive lines, a display memory, a control circuit, and a key scan circuit.Serial data is input to the µPD16312 through a three-line serial interface.This FIP controller/driver is ideal as a peripheral device for a single-chip microcomputer.

Features

Multiple display modes: 11-segment & 11-digit to 16-segment & 4-digit.
Key scanning: 6 x 4 matrix.
Dimming circuit: 8 steps.
High-withstanding-voltage output: VDD.
35 V MAX.
LED ports: 4 ch, 20 mA MAX.
General input port: On-chip 4 bit.
No external resistors necessary for driver outputs: P-ch open-drain + pull-down resistor output.
Serial interface: CLK, STB, DIN, DOUT.
