HT16512 -- 1/4 to 1/11 Duty VFD Controller |
|
| 概要 |
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.
