Everspin’s new xSPI product family is based on the EXpanded Serial Peripheral Interface, the latest JEDEC standard for non-volatile memory devices. xSPI products use Everspin’s unique industrial Spin-Transfer Torque (SST) MRAM technology, which delivers a significant reduction in switching energy compared to their Toggle MRAM.
xSPI MRAM devices offer high-performance, multiple I/O, and SPI-compatibility, and they feature a high-speed, low pin count SPI compatible bus interface. These persistent memory MRAM devices come in sizes from 8 Mb to 64 Mb and operate on a single 1.8 V power supply, delivering up to 400 MBps for both reads and writes via eight I/O signals. With unlimited read, write, and erase operations for the supported life of the product, Everspin boasts 10 years minimum data retention across the two operating temperature ranges – commercial (0°C to +70°C) and industrial (-40°C to +85°C). The quad and octal interface options run at 133 MHz and 200 MHz respectively.
The xSPI MRAM product evaluation board is an FPGA-based system with an industry-standard xSPI controller embedded for testing and evaluating the STT-MRAM device. As with many of Everspin’s evaluation boards, a host board is required to interface the technology for testing. Documentation regarding these requirements is not readily available at this time, but should you enter into discussions with Everspin, these details will be provided.
Please note that the board image displayed here is a placeholder while more documentation becomes available.
