Everspin Technologies has launched a dual-supply magnetoresistive random access memory (MRAM) product, designed to interface with logic products requiring low voltage I/Os.
According to Everspin, RAID systems using advanced logic controllers operating with 1.8 volt I/Os will be able to interface with MRAM to take advantage of its features. The MR0D08B dual supply MRAM product operates from a VDD main supply voltage of 3.0 to 3.6V and allows a wide, user defined I/O operating range by setting the VDDQ I/O supply voltage level from 1.65 to 3.6V. Applications using 1.8V logic controllers would set VDDQ at 1.8V to support direct connections between the controller and the MRAM, eliminating any requirements for level shifters.
The portfolio includes 8- and 16-bit parallel I/O products ranging from 256Kb through 4Mb densities in BGA and TSOP packages and serial peripheral interface I/O products ranging from 256Kb through 1Mb densities in DFN packages. The devices are housed in 8mm x 8mm, 48-BGA package with 0.75mm ball centres, Everspin said.
Saied Tehrani, chief operating officer of Everspin, said: “Everspin currently supplies MRAM products to a wide range of RAID controller applications. Our new dual- supply MRAM products are ideally suited for future generations of RAID controllers migrating to advanced processes requiring low voltage interface support.”
