HT16511A-1/4 to 1/12 Duty VFD Controller
General Description HT16511 is a VFD (Vacuum FluorescentDisplay) controller/driver that is driven on a 1/4 to 1/12 dutyfactor. HT16511 consists of 16 segment output lines, 4 grid outputlines, 8 segment/grid output drive lines, 4 LED output ports, HT16511acontrol circuit, a display memory, and a key scan circuit.
Serial data inputs to the HT16511 through a three-line serialinterface. This VFD controller/driver is an ideal MCU peripheraldevice. Features - HT16511 Logic voltage: 3.0V~5V
- HT16511 High-voltage output: VDD-35V max.
- HT16511 Multiple display (16-segment & 12-digit to 24-segment &4-digit)
- HT16511 16×2 matrix key scanning
- HT16511 8 steps dimmer circuit
- HT16511 4 LED output ports (20mA max.)
- HT16511 No external resistors necessary for driver output (providesPMOS open-drain and pull-low resistor output)
- HT16511 Serial interface with MCU (CLK, CSB, DI, DO)
- 4HT16511 4-pin QFP package
