RAMXEED ULTIMATE FeRAM family with guaranteed data retention of 10 years or more at 125°C

Guarantees 10 years or more of data retention at 125°C, a figure that is world-class for a nonvolatile RAM. Every product covers a wide -40°C to +125°C operating temperature range, and the lineup includes Automotive Grade products qualified to AEC-Q100 Grade 1.
Suitable for engine-compartment use and for placement next to hot industrial equipment.

While retaining the fast writes and low power that are FeRAM's strengths, Industrial Grade products support up to 10¹⁴write cycles. The endurance budgeting and wear-leveling logic that conventional nonvolatile memories such as EEPROM and flash require are no longer needed, so high-rate logging and real-time data capture can be implemented with confidence.

Available in industry-standard SOP and DFN packages, allowing your existing board layout to be reused without modification. Both SPI and I²C interfaces are offered, in two supply voltage ranges of 1.8V to 3.6V and 1.7V to 1.95V, facilitating a smooth replacement of the EEPROM or SRAM you use today.
