MR25H40 is a family of 4,194,304-bit magnetoresistive random access memory (MRAM) devices organized as 524,288 words of 8 bits. They are the ideal memory solution for applications that must store and retrieve data and programs quickly using a small number of I/O pins. They have serial EEPROM and serial Flash compatible read/write timing with no write delays and unlimited read/write endurance. Unlike other serial memories, with the MR25H40 family both reads and writes can occur randomly in memory with no delay between writes.
The MR25H40 family provides highly reliable data storage over a wide range of temperatures. The MR20H40 (50MHz) is offered with Industrial (-40° to +85 °C) range. The MR25H40 (40MHz) is offered with Industrial (-40° to +85 °C), Extended (-40 to 105°C), and AEC-Q100 Grade 1 (-40°C to +125 °C) operating temperature range options.
It is available in a 5 x 6mm, 8-pin DFN package. The pinout is compatible with serial SRAM, EEPROM, Flash, and FeRAM products.
Everspin Technologies is the leading developer and manufacturer of magnetic RAM (MRAM), offering stand-alone and embedded MRAM products. Everspin’s MRAM is the industry’s fastest non-volatile memory and provides unlimited endurance, unmatched reliability, 10-year-plus data retention and parallel and serial interfaces. As the world's first volume MRAM supplier, Everspin has established an MRAM intellectual property portfolio of more than 600 active patents and applications, many of which are fundamental and essential for MRAM technologies. Everspin’s current MRAM portfolio addresses persistent SRAM applications across three major markets: data center and storage; energy and infrastructure; and automotive and transportation. Everspin is on track to commercialize its next-generation Spin-Torque MRAM (ST-MRAM) products in 2012, offering a new storage class memory solution for non-volatile buffers and caching applications as well as a new nanosecond-class, gigabyte-per-second non-volatile storage tier.
