The MR256A08B is a 262,144-bit magnetoresistive random access memory (MRAM) device organized as 32,768 words of 8 bits. The MR256A08B offers SRAM compatible 35ns read/write timing with unlimited endurance. Data is always non-volatile for greater than 20-years. Data is automatically protected on power loss by low-voltage inhibit circuitry to prevent writes with voltage out of specification.
The MR256A08B is the ideal memory solution for applications that must permanently store and retrieve critical
data and programs quickly.
The MR256A08BSO35 is the 32-pin SOIC package in the commercial temperature (0 to +70 °C) ) range option shipped in trays.
