CHANDLER, Ariz.—Everspin Technologies has announced that Astro Digital has selected Everspin’s PERSYST 64Mb STT-MRAM for use on an upcoming Raven bus geosynchronous Earth orbit (GEO) satellite mission.
Everspin’s PERSYST MRAM is designed for embedded systems that require persistent, high-speed memory with strong endurance and data retention. Astro Digital will use Everspin’s EM064LXAQDG13IS1T 64Mb STT-MRAM as the primary fail-safe memory for the system boot process on its Raven bus. In satellite systems, boot memory stores the essential code needed to initialize spacecraft electronics and support system recovery. For this application, persistent MRAM provides non-volatile memory that can retain critical boot information without power and provide fast access during startup or recovery.
“Everspin’s leadership in MRAM is built on advancing memory technology to address the real-world challenges customers face,” said Sanjeev Aggarwal, president and CEO of Everspin Technologies. “Astro Digital’s selection of PERSYST shows how that innovation is being put to work in satellite applications with demanding requirements for boot, recovery, telemetry logging and data retention.”
GEO satellite systems operate over extended mission timelines in demanding orbital environments, placing stringent requirements on memory used for mission-critical functions. Everspin’s PERSYST MRAM’s radiation tolerance, high endurance and fast read and write performance support reliable spacecraft operation throughout long-duration missions.
“For this Raven bus application, Everspin’s 64Mb STT-MRAM was selected to support primary fail-safe memory for the system boot process,” said Billy Wahng, chief technology officer of Astro Digital. “Its non-volatility, endurance and fast access align with the requirements we evaluate for critical spacecraft functions in GEO satellite systems.”
Building on more than 16 years of deployment in mission-critical applications, Everspin’s PERSYST MRAM portfolio combines exceptional endurance, reliability and data retention with the industry’s fastest MRAM performance in its temperature range. The result is a memory solution designed for embedded systems that demand high write bandwidth and deterministic performance across aerospace, defense, medical, industrial and other high-reliability environments. PERSYST is available in a range of capacities and configurations designed to support demanding, next-generation embedded systems:
- Capacities of 64Mb, 128Mb and 256Mb: Optimized for mission-critical systems.
- Quad SPI Interface: Industry-standard compatibility for easy integration.
- Faster Write Speeds vs. NOR Flash: Reducing system overhead in real-time applications.
