FM1105-GATR

Specialized Overview

The FM1105-GATR is a nonvolatile dual state saver manufactured by Ramtron International Corporation, now part of Cypress Semiconductor. It operates at a supply voltage of 5V and provides data retention without requiring battery backup or complex write cycles. The device features a simple interface designed for rapid status saving in embedded systems.

Specialized Feature Summary

• Provides nonvolatile storage for critical system states
• Eliminates the need for external battery backup circuits
• Supports fast write operations for real-time applications

Specialized Applications

• Real-time clock (RTC) backup
• Microcontroller configuration storage
• System state preservation during power loss

Specialized Procurement Notes

Verify the manufacturer lineage from Ramtron to Cypress and subsequently to Infineon Technologies when sourcing this component. Confirm that the specific suffix denotes the tape and reel packaging format required for automated assembly processes. Ensure compatibility with standard 5V logic levels before integration into the design.

Specialized Selection Notes

Select this component when a simple, robust solution for retaining small amounts of critical data is required without the complexity of serial flash memory controllers. It is suitable for designs where write endurance and speed are prioritized over high-density storage capacity. Evaluate the package type availability against the board layout constraints.

Specialized Part Context

This device belongs to the FM11xx series of nonvolatile dual state savers. These components were originally developed by Ramtron International Corporation, which was acquired by Cypress Semiconductor. The technology leverages ferroelectric properties to provide instant write capabilities, distinguishing it from traditional EEPROM or Flash technologies.
