Description

The STFPC311 is a complete, low-cost, integrated solution for controlling and driving a front panel Vacuum Fluorescent Display (VFD). It is ideal for decreasing power consumption in standby mode by reducing the application standby current to a minimum. It also contains a built-in remote control decoder module.

Features

■ IC front panel controller/driver

■ Timing power standby management controller

■ IC power supply from 3.3V (VDD) to –30V (VSS)

■ Integrated VFD driver and controller

■ Infrared (IR) Remote Control (RC) Decoder (Philips or NEC format)

■ Drives many display modes (12 segments/16 digits to 20 segments/8 digits)

■ High voltage outputs (VDD - 33.3V max)

■ No external resistors necessary for driver outputs (P-channel open- drain with pull-down resistor outputs)

■ Key scanning (up to 12mm x 2mm matrix)

■ Led ports (4 channels, 20mA, max)

■ Serial interface (STB, CLK, DIN, and DOUT) communication protocol

■ Dimming circuit (adjustable up to 8 steps)

■ Supports auto-increment of display digit, which lightens the load on the MCU

■ Programmable 8 hot keys for the IR remote control command

■ Programmable 8 hot keys for key scan command

■ Low power consumption in standby mode

■ 2 general purpose input ports (SW1, SW2)

■ Available in PQFP-52 package

Applications

■ DVD players

■ VCD players

■ AV equipment like Home Stereo

■ POS Systems
