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.
