Introduction
The MR1A16A is a 2,097,152-bit magnetoresistive random access memory (MRAM) device organized as
131,072 words of 16 bits. The MR1A16A offers SRAM compatible 35 ns 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 MR1A16A is the ideal memory solution for applications that must permanently store
and retrieve critical data and programs quickly.
The MR1A16A is available in small footprint 400-mil, 44-lead plastic small-outline TSOP type-II package
or 8 mm x 8 mm, 48-pin ball grid array (BGA) package with 0.75 mm ball centers. These packages are
compatible with similar low-power SRAM products and other non-volatile RAM products.
The MR1A16A provides highly reliable data storage over a wide range of temperatures. The product is
offered with commercial temperature (0 to +70
extended temperature (-40 to +105
