Application of Medical Equipment MR25H40-4MB SPI Serial Interface MRAM

Everspin MR25H40-4MB SPI Serial Interface MRAM is suitable for non-volatile memory in medical equipment, such as in medical breathing, 4MB (MR25H40) MRAM can be used to store operation software program variables. The data stored in MRAM is stored during the ventilation. The MR25H40 is a 4194, 304-bit magnetic resistance random access memory (MRAM) device series, with 524,288 8-bit words. For applications that must be quickly stored and retrieved using a small number of I / O pins, they are ideal memory solutions. They have serial EEPROM and serial flash-compatible read / write timing, no write delay, and read / write life is not limited. Unlike other serial memories, use the MR2XH40 series, read, and write can randomly occur in memory, and there is no delay between writing. The MR25H40 series can provide highly reliable data storage within a variety of temperature ranges. MR25H40 (40 MHz) has an industrial (-40 ° to + 85 ° C), extended (-40 to 105 ° C) and AEC-Q100 1 (-40 ° C to + 125 ° C) operating temperature range options. Both use 5 x 6mm, 8-pin DFN package. This pin is compatible with serial SRAM, EEPROM, flash memory, and FERAM products. Bank of Microelectronics can provide samples and technical support guidance. The MR25H40 series is a MRAM SPI interface series, and the memory array is a serial clock (SCK), serial input (SI), serial output (SO), serial input (SI), serial output (SO), and serial input (SI), serial output (SCK) The four-pin interface, logical organization is 512kx8. The Everspin MRAM implements the command subset of the serial interface EEPROM and the serial interface flash component. This allows the MRAM SPI to replace these components in the same slot and interoperate on a shared SPI bus. The MRAM SPI provides excellent write speed, unlimited durability, low-protection, and simple, reliable data reserves. FQJ, read full text
