AD6315 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.
