STFPC311  
Front panel controller/driver with standby power management  
Datasheet − not recommended for new design  
Features  
■ IC front panel controller/driver  
■ Timing power standby management controller  
■ IC power supply from 3.3V (V ) to –30V (V  
)
SS  
DD  
PQFP-52  
■ Integrated VFD driver and controller  
■ Infrared (IR) Remote Control (RC) Decoder  
Description  
(Philips or NEC format)  
The STFPC311 is a compte, low-cost,  
■ Drives many display modes (12 segments/16  
integrated solution fr 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  
curreno a minimum. It also contains a built-in  
rmote control decoder module.  
digits to 20 segments/8 digits)  
■ High voltage outputs (V - 33.3V max)  
DD  
■ 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 standby mode of operation, a valid key  
press or signal from the infrared decoder will start  
a proper power-up (see Figure 6 on page 13).  
■ Serial interface (STB, CLK, D , and D  
)
OUT  
IN  
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 segment 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  
communication protocol  
■ Dimming circuit (adjustablup to 8 steps)  
■ Supports auto-incremeof display digit, which  
lightens the load n the MCU  
■ Programmable 8 hot keys for the IR remote  
control command  
(STB, D , D  
, and CLK).  
IN  
OUT  
■ Proammable 8 hot keys for key scan  
Additionally, this IC can support two general-  
purpose input switches (SW1 and SW2).  
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
