INTRODUCTION

The MR25H40 is a 4,194,304-bit magnetoresistive random access

memory (MRAM) device organized as 524,288 words of 8 bits. The

MR25H40 offers serial EEPROM and serial Flash compatible read/write

timing with no write delays and unlimited read/write endurance.

4Mb Serial SPI MRAM

RoHS

Unlike other serial memories, both reads and writes can occur randomly in memory with no delay between

writes. The MR25H40 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 MR25H40 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 MR25H40 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.
