Everspin Technologies MR4A08B & MR4A16B 16Mb Parallel MRAMs
Everspin Technologies MR4A08B and MR4A16B 16Mb Parallel MRAM devices provide SRAM compatible 35ns read/write timing with unlimited endurance. The Everspin Technologies MR4A08B is a 16,777,216-bit Magnetoresistive Random Access Memory (MRAM) device organized as 2,097,152 words of 8 bits.
The Everspin Technologies MR4A16B is organized as 1,048,576 words of 16 bits. For both MRAM devices, data is 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 MR4A08B is available in small footprint 400-mil, 44-lead plastic small-outline TSOP type-II package or 10mm x 10mm, 48pin ball grid array (BGA) package with 0.75mm ball centers. The MR4A16B is available in small footprint 48pin ball grid array (BGA) package and a 54-pin Thin Small Outline Package (TSOPII).
Both products provide highly reliable data storage over a wide range of temperatures. They are offered with commercial temperature (0 to 70°C), industrial temperature (-40 to 85°C), and automotive temperature (-40 to 125°C) range options.
