General Description

HT16512 is a VFD (Vacuum Fluorescent Display) con-

troller/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.
