DESCRIPTION

MR2xH40 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 EE-

PROM and serial Flash compatible read/write timing with no write delays and unlimited read/write

endurance. Unlike other serial memories, with the MR2xH40 family both reads and writes can occur

randomly in memory with no delay between writes.

The MR2xH40 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.

Both are available in a 5 x 6mm, 8-pin DFN package. The pinout is compatible with serial SRAM,

EEPROM, Flash, and FeRAM products.
