HT16511
-- 1/8 to 1/16 Duty VFD Controller
General
Description
HT16511 is a VFD (Vacuum
Fluorescent Display) controller/driver that is
driven on a 1/8 to 1/16 duty factor. It consists
of 12 segment output lines, 8 grid output lines,
8 segment/grid output drive lines, 5 LED output
ports, a control circuit, a display memory, and
a key scan circuit.
Serial data inputs to the
HT16511 through a three-line serial interface.
This VFD controller/driver is ideal as a
peripheral device for an MCU.
