HT16512
-- 1/4 to 1/11 Duty VFD Controller
General
Description
HT16512 is a VFD (Vacuum
Fluorescent Display) controller/driver that is
driven on a 1/4 to 1/11 duty factor. It consists
of 11 segment output lines, 6 grid output lines,
5 segment/grid output drive lines, 4 LED output
ports, a control circuit, a display memory, and
a key scan circuit.
Serial data inputs to the
HT16512 through a three-line serial interface.
This VFD controller/driver is ideal as a
peripheral device for an MCU.
