IN Brief:
- Everspin has completed production qualification for its 64Mb high-reliability xSPI MRAM.
- The memory is aimed at industrial, medical, automotive, and aerospace applications.
- Higher-density 128Mb and 256Mb devices are due to follow in 2026.
Everspin Technologies has completed full production qualification for its 64Mb high-reliability xSPI MRAM, marking the latest expansion of its persistent memory portfolio for harsh-environment and long-life embedded systems.
The device is aimed at applications in sectors including industrial, medical, automotive, and aerospace, where memory components are required to maintain data integrity under demanding operating conditions.
Everspin said the 64Mb part has achieved full production qualification to AEC-Q100 Grade 1 and is now available for customer orders. The company is positioning the device for systems exposed to temperature extremes, radiation, and power-loss conditions where data persistence is critical.
The product sits within Everspin’s PERSYST xSPI family, which uses the JEDEC xSPI interface standard for non-volatile memory. Across the family, the devices operate from a 1.8V supply and support clock frequencies up to 200 MHz, with read and write performance of up to 400 MB/s through an eight-bit interface.
The architecture is intended to provide an alternative to combinations of SRAM and flash in embedded systems requiring non-volatility, high endurance, and fast access. Everspin has also highlighted its suitability for designs where memory reliability is a significant part of overall system resilience.
The qualification milestone forms part of a broader product roadmap. Everspin said its 128Mb high-reliability xSPI MRAM is expected to complete production qualification in May 2026, while a 256Mb version is scheduled to reach the same stage in July 2026, with volume availability planned for the second half of the year.
Persistent memory technologies have continued to attract attention in applications where data retention, fast write performance, and resistance to environmental stress are required in a single device. With the 64Mb device now fully qualified, Everspin is extending that option further into production programmes that demand both endurance and long-term availability.
