Everspin’s automotive-temperature MRAM meets harsh environment demands in BMW S 1000 RR racing bike

CHANDLER, USA: Automotive-temperature MRAM technology from Everspin Technologies is helping optimize performance of the BMW S 1000 RR Motorrad Motorsport Super Bike that made its international competition debut in 2009.

Having passed the extreme environment test with BMW, Everspin is also introducing a family of AEC-Q100 fully qualified MRAM products for a variety of automotive-related applications.

Everspin’s 4Mb MR2A16AMYS35 MRAM provides a robust memory solution for the BMW Motorrad Motorsport engine control unit (ECU) called RSM5, storing important calibration data that controls the motorcycle during a race. Prior to each competition, the bike’s computer is fine-tuned for peak performance and optimized for the individual rider, specific track and exact race conditions.

The MRAM chip stores adjustable engine parameters such as data related to a racing bike’s fuel injection, ignition, braking and acceleration. Always non-volatile, power loss after writes to MRAM does not affect data integrity.

“We are extremely pleased with the advantages that Everspin’s MRAM brings to our bike on race day,” said Ralf Schmidt, electronic development leader, BMW Motorrad Motorsport. “We selected MRAM to store critical data for our Superbike due to MRAM’s excellent temperature performance and inherent reliability.”
