STMicroelectronics STFPC311BTR

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
