Freescale is providing MRAM non-volatile memory technology for environmentally harsh applications, such as military, aerospace, industrial and automotive systems. Angstrom Aerospace recently announced the use of Freescale's extended temperature range 4Mbit MRAM in its magnetometer subsystem, which will be launched into space on board a Japanese research satellite.
Angstrom Aerospace is using Freescale's MRAM in its Tohoku-AAC MEMS Unit (TAMU), a magnetometer subsystem for the Japanese research satellite called SpriteSat. In developing the Satellite subsystem, Angstrom Aerospace worked closely with Dr. Johan Akerman, a renowned Swedish professor of material physics and applied spintronics at the Royal Institute of Technology.
"I've worked with MRAM for years, and when it comes to reliability and endurance for data storage, there is no comparison to Freescale's MRAM products," said Dr. Johan Akerman. "Freescale's 4Mbit MRAM device replaces both flash and battery-backed SRAM in Angstrom's module for the SpriteSat. The ability to reconfigure critical programs and route definitions during various stages of a satellite mission is a significant benefit."
TAMU plans to provide SpriteSat with magnetometer data of the Earth's magnetic field. SpriteSat is built by the Tohoku University located in Sendai, Japan, under the supervision of Professor Kazuya Yoshida. Scheduled to be launched in late 2008, SpriteSat's mission is to monitor "sprite" phenomenon (lightning effects) in Earth's upper atmosphere.
Angstrom Aerospace selected Freescale's 4Mbit MRAM device because it combines non-volatile memory with extended temperature operation, unlimited endurance and long-term data retention even when the power fails. The MRAM stores program data and FPGA configuration data on a single memory, allowing Angstrom Aerospace to reduce all storage requirements to one chip, reducing board area. At the same time, the flexibility of MRAM storage allows the system to be reconfigured significantly in space.
"Our extended temperature MRAM provides unique high temperature and high reliability capabilities for rugged system designs, such as the TAMU," said David Bondurant, MRAM product manager at Freescale. "MRAM benefits also extend to the transportation and industrial markets, where Freescale is working with developers who require growing amounts of fast but cost-effective memories that are ideally non-volatile and capable of large numbers of read and write cycles."
