INTRODUCTION
The MR25H256 is a 262,144-bit magnetoresistive random access memory (MRAM) device orga-
nized as 32,768 words of 8 bits. The MR25H256 offers serial EEPROM and serial
Flash compatible read/write timing with no write delays and unlimited read/write
endurance.
Unlike other serial memories, both reads and writes can occur randomly in memo-
ry with no delay between writes. The MR25H256 is the ideal memory solution for applications that must
store and retrieve data and programs quickly using a small number of I/O pins.
The MR25H256 is available in either a 5 mm x 6 mm 8-pin DFN package or a 5 mm x 6 mm 8-pin DFN
Small Flag package. Both are compatible with serial EEPROM, Flash, and FeRAM products.
The MR25H256 provides highly reliable data storage over a wide range of temperatures. The product is
offered with industrial (-40° to +85 °C) and AEC-Q100 Grade 1 (-40°C to +125 °C) operating temperature
range options.
