General Description
HT16511 is a VFD (Vacuum Fluorescent Display) controller/driver that is driven on a 1/8 to 1/16 duty factor.
It consists of 12 segment output lines, 8 grid output lines, 8 segment/grid output drive lines, 5 LED output ports, a control circuit, a display memory, and a key scan circuit.
Key Features
- Logic voltage: 5V.
- High-voltage output: VDD-35V max.
- Multiple display.
- 4-bit general purpose input port.
- No external resistors necessary for driver output (12-segment & 16-digit to 20-segment & 8-digit).
- 12´4 matrix key scanning.
- 8 steps dimmer circuit.
- 5 LED output ports (20mA max. ) (provides PMOS open-drain and pull-low resistor output).
- Serial interface with MCU (CLK, CS, DI, DO).
- 52-pin QFP package.
