Functional description

STFPC311

The STFPC311 receives serial data from the microcontroller through the SPI interface,

latches the data, and then masks the inputs from the MCU. This data consists of commands

followed by data. There are 4 types of commands:

● configuration,

● data,

● address, and

● display.

The STFPC311 integrates the supply standby power management functionality, remote

control decoder, and a 28-bit VFD driver. Microcontrollers usually run the first two tasks.

t(s) This device reduces the stand-by power consumption of the whole Front Panel application

as well as the hardware by integrating the infrared (IR) remote control decoder.

uc A dedicated supply voltage powers the STFPC311 directly from the main supply board.

d When power is plugged in, control of the power supply management is done using the

ro following pins:

P 1. STBY,

te 2. IR_DATA_IN, and

Obsolete Product(s) - Obsole 3. READY.
