STFPC311BTR

Overview

The STFPC311BTR is a front panel controller and driver integrated circuit designed for Vacuum Fluorescent Displays (VFD). It operates with a supply voltage range from 3.3V to -30V. The device integrates a VFD controller, an IR remote control decoder supporting Philips or NEC formats, and a display memory. It features 12 segment output lines, 8 grid output lines, and 8 shared drive lines. The unit communicates via an SPI interface and includes a dimming circuit with up to 8 adjustable steps.

Feature Summary

• Integrates VFD controller and driver with built-in IR remote control decoder
• Supports multiple display modes including 12 segments/16 digits
• Includes programmable hot keys for IR and key scan commands
• Features low power consumption in standby mode

Applications

• DVD players
• VCD players
• AV equipment like Home Stereo
• POS Systems

Procurement Notes

Verify the specific suffix 'BTR' against official STMicroelectronics documentation to confirm tape and reel packaging details. Ensure the component matches the PQFP-52 package specification. Cross-reference the part number with current product status to confirm availability, as the base model STFPC311 may have different lifecycle statuses.

Selection Notes

Select this component for applications requiring integrated VFD driving and IR decoding in a single package. It is suitable for designs needing reduced standby current and simplified MCU interfaces due to auto-increment capabilities. Consider the operating temperature range and supply voltage requirements when designing the power management section.

Part Context

The STFPC311BTR belongs to STMicroelectronics' portfolio of front panel controllers. It is part of a series designed to decrease power consumption in standby mode by minimizing application standby current. The device replaces discrete solutions by integrating the controller, driver, and decoder into one IC.

Replacement Considerations

Check for direct substitutes within the STFPC series. Verify pin compatibility and electrical specifications if considering alternative VFD controllers. Confirm that any replacement supports the required IR decoder formats and display memory size.
