1/4- to 1/12-DUTY FIP
TM
(VFD) CONTROLLER/DRIVER
DESCRIPTION
The
µ
PD16315 is a FIP (Fluorescent Indicator Panel, or Vacuum Fluorescent Display) controller/driver that is driven on a
1/4- to 1/12- duty factor. It consists of 16 segment output lines, 4 grid output lines, 8 segment/grid output drive lines, a
display memory, a control circuit, and a key scan circuit. Serial data is input to the
µ
PD16315 through a three-line serial
interface. This FIP controller/driver is ideal as a peripheral device for a single-chip microcomputer.
