HT16515中文资料合泰数据手册PDF规格书

General 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. Serial data inputs to the HT16515 through a three-line serial interface. This VFD controller/driver is an ideal MCU peripheral device.

Features

• Logic voltage: 3.0V~5.5V

• High-voltage output: VDD-35V max.

• Multiple display (16-segment & 12-digit to 24-segment & 4-digit)

• 16 x 2 matrix key scanning

• 8 steps dimmer circuit

• 4 LED output ports

• No external resistors necessary for driver output (provides PMOS open-drain and pull-low resistor output)

• Serial interface with MCU (CLK, CS, DI, DO)

• 44-pin QFP/LQFP packages

Applications

• Consumer products panel function control

• Industrial measuring instrument panel function control
