HT16515 -- 1/4 to 1/12 Duty VFD Controller
|
|
| 概要 |
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. |
| 特点 |
Logic voltage: 3.0V~5V
High-voltage output: VDD-35V max.
Multiple display (16-segment & 12-digit to
24-segment & 4-digit)
16×2 matrix key scanning
8 steps dimmer circuit
4 LED output ports (20mA max.)
No external resistors necessary for driver output
(provides PMOS open-drain and pull-low resistor
output)
Serial interface with MCU (CLK, CSB, DI, DO)
44-pin QFP package |
