FM31276-G

Specialized ICS Overview

The FM31276-G is a 64 kBit Ferroelectric RAM (F-RAM) processor companion integrated with a Real-Time Clock (RTC). It features an I2C interface operating at frequencies up to 1 MHz. The device includes a power failure detection circuit, a watchdog timer, and battery switching capability. It operates within a voltage range of 4 V to 5.5 V and supports industrial temperature ranges from -40 °C to 85 °C. The component is housed in a 14-SOIC package.

Specialized ICS Feature Summary

• Integrated 64 kBit F-RAM memory with non-volatile data retention
• Built-in Real-Time Clock (RTC) functionality
• Power failure detection and automatic data protection
• Watchdog timer for system reliability

Specialized ICS Applications

• Processor-based systems requiring persistent timekeeping
• Industrial control applications needing reliable data logging
• Systems requiring fast write speeds and high endurance

Specialized ICS Procurement Notes

Verify the specific ordering suffix and package variant against official Infineon documentation before procurement. Confirm that the 14-SOIC tube packaging aligns with assembly requirements. Check for any recent product discontinuation notices or end-of-life notifications associated with this part number to ensure long-term supply availability.

Specialized ICS Selection Notes

Select the FM31276-G when a combined solution for non-volatile storage and real-time clocking is required. Ensure the system voltage falls within the 4 V to 5.5 V operating range. Consider the 1 MHz I2C speed and industrial temperature rating (-40 °C to 85 °C) if the application demands robust performance in varying environmental conditions.

Specialized ICS Part Context

This component belongs to the FM3127x series of processor companions by Infineon Technologies. These devices integrate F-RAM technology with RTC and supervisory functions to simplify system design. The FM31276-G specifically offers 64 kBit density, distinguishing it from higher-capacity variants like the FM31278.
