HT16515 - 1/4 to 1/12 Duty VFD Controller

Description

HT16515 is a VFD (Vacuum Fluorescent Display) controller/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.

Features

  • Logic voltage: 5V.
  • High-voltage output: VDD-35V max.
  • Multiple display.
  • 4 LED output ports (20mA max. ).
  • No external resistors necessary for driver output (16-segment & 12-digit to 24-segment & 4-digit).
  • 16´2 matrix key scanning.
  • 8 steps dimmer circuit (provides PMOS open-drain and pull-low resistor output).
  • Serial interface with MCU (CLK, CS, DI, DO).
  • 44-pin QFP package.
