The MR256D08B is a 262,144-bit magnetoresistive random access memory (MRAM) device organized as 32,768 words of 8 bits. It supports I/O voltages from +1.65 to +3.6 volts. The MR256D08B offers SRAM compatible 45ns 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 MR256D08B is the ideal memory solution for applications that must permanently store and retrieve critical data and programs quickly.
The MR256D08BMA45 is the 48-pin ball grid array (BGA) package in the commercial temperature (0 to +70 °C) range option shipped in trays.
