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 EEPROM 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.

FEATURES
• No write delays
• Unlimited write endurance
• Data retention greater than 20 years
• Automatic data protection on power loss
