Additional Details

The FM1105-G offers a seamless replacement for traditional SRAM, while adding nonvolatile data storage. The device automatically stores the SRAM data into the nonvolatile cells upon power loss, ensuring data retention for many years. When power is restored, the data is automatically recalled from the nonvolatile cells back into the SRAM. This process is transparent to the user, simplifying the system design and eliminating the need for complex backup power circuits. The device operates at 5V and features a fast access time of 35ns. It is available in SOIC package and is ideal for applications requiring fast and reliable nonvolatile memory. The non-volatility is achieved using Quantum Trap technology, which provides superior endurance and data retention compared to traditional EEPROM or Flash memory. The device is designed to withstand a wide range of operating temperatures and is suitable for use in demanding industrial and automotive applications. This component is often used to store critical configuration data, application parameters, and logged data in systems where data loss cannot be tolerated.
