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