RAMSUN,a NETSOL agent,recommended an excellent SPI MRAM chip S3A1604V0M-JI1ARS.This serial SPI MRAM chip is a kind of spin transfer torque magnetoresistive random access memory(STT-MRAM),which has SPI bus interface,XIP(local execution)function and data protection mechanism based on hardware/software.SPI(Serial Peripheral Interface)is a synchronous serial communication interface with command,address and data signals.
The serial interface of SPI MRAM chip S3A1604V0M-JI1ARS has fewer pins than the parallel interface,higher spatial integration,and is easier to configure on the system.It has the same non-volatile characteristics as flash memory,FeRAM or(nv)SRAM,and has the function of unlimited reading and writing,and does not need external ECC error correction function,so it is suitable for code storage and data recording in various industrial equipment.
S3A1604V0M-JI1ARS chip supports XIP for reading and writing,and can read and write data quickly.The program code can be directly stored in MRAM to run,and it is not necessary to carry the code to SRAM after power-on as in the traditional scheme,which significantly simplifies the system startup process.At the same time,SPI MRAM chip S3A1604V0M-JI1ARS supports JEDEC reset,with extremely low power consumption and durable data,which can be stored for more than 20 years.S3A1604V0M-JI1ARS memory has a capacity of 16M bit,a wide operating voltage range,a wide operating temperature range of-40℃to 105℃in the range of 2.70~3.60V,and can adapt to various extreme environmental temperatures.
If your project is currently facing the problems of short erase life of traditional NOR Flash,high cost of external ECC or data loss due to power failure,this SPI interface STT-MRAM is a very competitive alternative.Welcome to consult Yingshang for detailed specifications and test samples.
