General Description

The AD6315 is a VFD (Vacuum Fluorescent Display

or fluorescent Indicator Panel) driver that is driven

on a 1/4- to 1/12- duty factor. It consists of 16

segments and 4 grids output lines, 8 segments /

grid output driving lines, a display memory, a control

circuit, and a key scan circuit. Serial data is input to

the AD6315 through a 3-wire serial interface. This

VFD driver is ideal as a peripheral device for a

single-chip microcomputer.
