Everspin Technologies' family of serial interface magnetoresistive random access memory (MRAM) devices now has a 4Mb solution that highlights write speeds, endurance, low standby and operating power, and reliable data retention.

The MR25H40, designed for systems that utilize the serial peripheral interface (SPI) bus found in many microprocessors, microcontrollers and other integrated circuits, takes advantage of Everspin's SPI MRAM family, which runs at clock speeds up to 40MHz and provides automatic data protection on power loss and unlimited endurance with more than 20 years data retention without write delay.

"Customers who may have been faced with limited options in the past can now use the 4Mb serial MRAM to directly replace EEPROM, Flash and FeRAM, and experience no write delays and unlimited read/write endurance," said Phill LoPresti, president and CEO of Everspin Technologies. "The fast write time of the 4Mb serial MRAM also allows for new and exciting application architectures such as dynamically reconfigurable FPGAs."

MRAM can replace many of today's SPI EEPROM and Flash components, as Serial MRAM implements a subset of commands common to these components.
