Everspin Tech MR1A16AMYS35

The MR1A16A is a 2,097,152-bit magnetoresistive random access memory (MRAM) device organized as 131,072 words × 16 bits. The MR1A16A offers SRAM-compatible 35 ns read/write timing with unlimited endurance. Data is always nonvolatile, with a retention period exceeding 20 years. A low-voltage inhibit circuit automatically protects data during power-down, preventing writes when voltage is out of specification.

The MR1A16A is an ideal memory solution for applications requiring permanent storage and fast retrieval of critical data and programs.

The MR1A16A is available in a compact 48-pin BGA package and a 44-pin TSOP Type 2 package. These packages are compatible with similar low-power SRAM products and other nonvolatile RAM products.

The MR1A16A provides highly reliable data storage across a wide temperature range. The product is offered in commercial (0 to +70 °C), industrial (−40 to +85 °C), extended (−40 to +105 °C), and AEC-Q100 Grade 1 (−40 to +125 °C) operating temperature range options.
