STFPC311

Front panel controller/driver

with standby power management

Features

■ IC front panel controller/driver

■ Timing power standby management controller

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

)

■ Integrated VFD driver and controller

PQFP-52

■ Infrared (IR) Remote Control (RC) Decoder

(Philips or NEC format)

Description

■ Drives many display modes (12 segments/16

digits to 20 segments/8 digits)

The STFPC311 is a complete, low-cost,

■ High voltage outputs (V - 33.3V max)

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.

■ 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)

While in the standby mode of operation, a valid

key press or signal from infrared decoder will start

a proper power-up see Figure 6 on page 12.

■ Serial interface (STB, CLK, D , and D

)

OUT

communication protocol

■ Dimming circuit (adjustable up to 8 steps)

The STFPC311 integrates a VFD controller with a

driver that is run on a 1/8 to 1/16-duty factor. It

consists of 12 segments output lines, 8 grid output

lines, 8 shared segments/grid output drive lines, a

display memory, a control circuit, and a key scan

circuit. Serial data is input to the STFPC311

through the SPI Interface of a microcontroller

■ 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

(STB, D , D

, and CLK).

OUT

■ Low power consumption in standby mode

■ 2 general purpose input ports (SW1, SW2)

■ Available in PQFP-52 package

Additionally, this IC can support 2 general

purpose input switches (SW1 and SW2).

Features

■ DVD players

■ VCD players

■ AV equipment like Home Stereo

■ POS Systems
