Everspin is introducing a new family of MRAM products, with a Serial Peripheral Interface (SPI) bus. The new family is called MR24H and includes 256Kb, 512Kb and 1Mb products. These Everspin MRAM devices require no write delay, run at clock speeds as fast as 40 MHz and have unlimited endurance with more than 20 years data retention. 

The MR25H256 (256Kb), MR25H512 (512Kb) and MR25H10 (1Mb) serial MRAM products operate from  2.7 to 3.6 volts while offering low standby and operating currents as well as a 3 uA (typical) sleep mode to further improve the system power consumption. They are byte-organized internally, containing 32KB, 64KB and 128KB of data respectively. Industry-standard serial SPI command codes and timing enable easy connection to existing MCU and system designs. The devices are housed in low profile 8-pin RoHS-compliant DFN packages that are pin-out and footprint compatible with serial EEPROM, Flash and FeRAM products in comparable DFN or SOIC packages.
