MR25H10 Summary of contents
Page 1
... The MR25H10 is a 1,048,576-bit magnetoresistive random access memory (MRAM) device organized as 131,072 words of 8 bits. The MR25H10 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 memory with no delay between writes. The MR25H10 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 MR25H10 is available in a small footprint 8-pin DFN package that is compatible with serial EEPROM, Flash, and FeRAM products. The MR25H10 provides highly reliable data storage over a wide range of temperatures. The product is of- fered with commercial temperature (0° to +70 °C), industrial temperature (-40° to +85 °C), and automotive temperature (-40° ...
