1 / 12 page  HT16512 1/4 to 1/11 Duty VFD Controller 1 December 24, 1999 Features · Logic voltage: 5V · High-voltage output: VDD-30V max. · Multiple display (11-segment & 11-digit to 16-segment & 4-digit) · 6´4 matrix key scanning · 8 steps dimmer circuit · 4 LED output ports · 4-bit general purpose input port · No external resistors necessary for driver output (provides PMOS open-drain and pull-low resistor output) · Serial interface with MCU (CLK, CS, DI, DO) Applications · Consumer products panel function control · Industrial measuring instrument panel func- tion control · Other similar application panel function control 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. |
