MRAM(Magnetic Random Access Memory)uses magnetic tunnel junction to store data,which has the advantages of high-speed reading and writing of SRAM,high density of DRAM and non-volatility of Flash.Compared with the traditional storage technology,Everspin's MRAM chip can be written directly without erasing,which significantly improves the real-time response capability of the system.At the same time,its low power consumption characteristics are especially suitable for battery-powered equipment,the leakage current is much lower than SRAM,and the manufacturing cost is more competitive.
 

 

　　MR25H128A,an Everspin brand MRAM memory chip sold by Yingshang,is an ideal memory for applications that must store and retrieve data and programs quickly with a minimum number of pins.It can provide AEC-Q100 Grade 1 and Grade 3 qualification options.As a serial SPI interface MRAM with a capacity of 128Kb,MR25H128A works at a voltage of 3.3V,supports a clock frequency of 40MHz,and can realize zero delay writing operation.This means that in data-intensive applications,such as industrial control,automotive electronics or smart meters,the processor does not have to wait for the storage cycle,thus improving the overall system efficiency.


 

 

　　The biggest highlight of Everspin MR25H128A is its durability of unlimited writing.Traditional EEPROM or Flash has the limitation of erasing life,while MRAM is based on magnetic storage mechanism,which can be written infinitely in theory,completely solving the problem of storage medium wear.In addition,the data retention time is more than 20 years,even in the case of power failure,the storage content is still intact,and no additional backup circuit is needed.
 

 

　　Everspin MRAM chip provides a variety of data protection mechanisms:block write protection can prevent key data from being accidentally tampered with,and low current sleep mode further reduces the standby power consumption of the system.For automotive and industrial applications,Everspin MR25H128A offers AEC-Q100 Grade 1 and Grade 3 certification options,and its operating temperature range covers-40 C to 125°C,meeting the stringent environmental requirements.
 

 

　　As a high-speed serial SPI interface MRAM memory chip of Everspin,MR25H128A is packaged in an 8-pin DFN package(small flag package)conforming to RoHS standard,which is compatible with serial EEPROM,Flash and FeRAM pins and can be directly replaced without changing PCB design.Its humidity sensitivity grade is MSL-3,which is convenient for production,storage and mounting.
 

 

　　As an authorized agent of Everspin,Yingshang fully promotes the high-performance MRAM chip,MR25H128A.Whether it's automotive electronics that pursue ultimate reliability or industrial sensors that emphasize low power consumption,Everspin MRAM can help product performance jump with excellent durability and instant data retention.If you have a demand for this product,please feel free to contact.
