The MR2A08A and MR2A16A are a 4,194,304-bit magnetoresistive random access memory (MRAM) device organized as 524,288 words of 8 bits and 262,144 words of 16 bits respectively. They 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 MR2A08A/MR2A16A is the ideal memory solution for applications that must permanently store and retrieve critical data and programs quickly.
The MR2A08A is available in a small footprint 400-mil, 44-lead plastic small-outline TSOP type 2 package or an 8 mm x 8 mm, 48-pin ball grid array (BGA) package with 0.75 mm ball centers. The M2A16A is available in a small footprint 48-pin ball grid array (BGA) package and a 44-pin thin small outline package (TSOP Type 2). These packages are compatible with similar low-power SRAM products and other non-volatile RAM products.
The MR2A08A and MR2A16A provide highly reliable data storage over a wide range of temperatures. The product is offered with commercial temperature range (0 to +70 °C), industrial temperature range (-40 to +85 °C), and AEC-Q100 Grade 1 temperature range (-40 to +125 °C) options.
