Everspin Technologies (NASDAQ: MRAM) announced that Astro Digital has selected its PERSYST 64Mb STT-MRAM memory product for use on an upcoming Raven bus geosynchronous Earth orbit (GEO) satellite mission.

The specific component, Everspin's EM064LXAQDG13IS1T 64Mb STT-MRAM, will serve as the primary fail-safe memory for the system boot process on Astro Digital's Raven bus. Boot memory stores the essential code needed to initialize spacecraft electronics and support system recovery.

"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."

The PERSYST MRAM is a non-volatile memory product, meaning it retains data without power. Everspin states the product offers radiation tolerance and fast read and write performance, characteristics the company says support spacecraft operation in long-duration orbital missions.

Everspin's PERSYST portfolio is available in capacities of 64Mb, 128Mb and 256Mb, and uses a Quad SPI interface. The company, headquartered in Chandler, Arizona, markets the product line for use in aerospace, defense, medical and industrial applications.
