General Description
HT16515 is a VFD (Vacuum Fluorescent Display) con-
troller/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, 4 LED output ports, a
controlcircuit,adisplaymemory,andakeyscancircuit.
Serial data inputs to the HT16515 through a three-line
serial interface. This VFD controller/driver is an ideal
MCU peripheral device.
