FM31L278-GTR

Specialized ICS Overview

The FM31L278-GTR is a 256-Kbit integrated processor companion featuring ferroelectric random access memory (F-RAM) in a 14-pin SOIC package. It integrates a real-time clock/calendar, low-voltage reset, watchdog timer, and event counters. The device operates at 2.7 V to 3.6 V with an I2C interface supporting up to 1 MHz. Key specifications include 10^14 read/write endurance, 151-year data retention, and industrial temperature range (-40°C to +85°C).

Specialized ICS Feature Summary

• 256-Kbit F-RAM organized as 32K x 8 bits with NoDelay writes.
• Integrated Real-Time Clock/Calendar with software calibration and battery backup.
• Processor supervisor functions including programmable low-VDD reset and watchdog timer.
• Dual 16-bit battery-backed event counters and lockable 64-bit serial number.

Specialized ICS Applications

• Processor-based systems requiring nonvolatile memory and timekeeping.
• Industrial control systems needing high-endurance logging.
• Embedded devices requiring power-fail detection and system supervision.

Specialized ICS Procurement Notes

Verify the specific suffix 'GTR' corresponds to the Tape & Reel packaging format as indicated in local product fields. Confirm RoHS compliance and UL recognition status through official Infineon documentation before procurement. Ensure the ordering part number matches the exact density and package requirements for the target application.

Specialized ICS Selection Notes

Select the FM31L278 variant over the FM31L276 when 256 Kbit of memory capacity is required. Ensure the design supports the 2.7 V to 3.6 V operating voltage range. Verify that the I2C bus speed does not exceed 1 MHz. Consider the 14-SOIC package dimensions for PCB layout constraints.

Specialized ICS Part Context

This component belongs to the FM31L27x family of integrated processor companions from Infineon Technologies (formerly Cypress Semiconductor). It combines F-RAM memory with essential supervisory functions to replace multiple discrete components in embedded designs.
