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

control circuit, a display memory, and a key scan circuit.

Serial data inputs to the HT16515 through a three-line

serial interface. This VFD controller/driver is an ideal

MCU peripheral device.
