ISSI SRAM is a widely used traditional memory chip in many hardware research and development scenarios,such as embedded storage,industrial control,intelligent devices,etc.However,due to the volatile storage architecture,there are many pain points such as data loss due to power failure,cumbersome supporting components,and limited service life.NETSOL MRAM,as a new generation of high-performance nonvolatile memory chip,can seamlessly and directly replace ISSI SRAM,which has the advantages of compatibility,adaptability and performance,and does not need to greatly change hardware and programs.It is the preferred solution to upgrade the traditional SRAM storage scheme at this stage.
NETSOL MRAM strictly follows the timing design of asynchronous SRAM,which is a standard industry standard,and is highly matched with the timing parameters of ISSI SRAM.The hardware PINs and electrical protocols are completely compatible,and the direct replacement of pin can be realized without modifying PCB circuit board or adjusting hardware circuit,which greatly reduces the research and development cost and cycle of equipment iteration and chip replacement.At the same time,NETSOL MRAM is equipped with a standard read/write cycle speed of 35ns,which perfectly adapts to the operation speed of ISSI SRAM of the same level,and the operation stability and response speed of the equipment are not affected by replacement.
The traditional ISSI SRAM is a volatile memory device,and the data will be lost immediately after the equipment is powered off.The conventional solution in the industry needs to be matched with external capacitors,spare batteries and other accessories,and the data backup is completed by external energy storage devices,which not only has complicated components,but also has the risk of data loss caused by aging capacitors and battery power loss.NETSOL MRAM adopts a new non-volatile storage architecture,and does not need to rely on external accessories such as Vcap capacitor and Vbatt standby power supply.After the NETSOL MRAM chip completes the reading and writing operation,the data can be solidified and stored immediately,completely avoiding the potential instability caused by external accessories.
S3A2004R0M is the mainstream core model in NETSOL MRAM series,which adapts to ISSI SRAM replacement.With strong parameter adaptability and high working condition stability,it is widely used in various embedded and industrial control storage scenarios.The specific parameters of NETSOL MRAM series S3A2004R0M are as follows:
①storage capacity:2Mbit
②communication interface:support Single/Dual/Quad SPI multi-specification serial interface.
③working voltage:standard wide voltage design,voltage range of 1.71~1.98V,suitable for most conventional hardware power supply systems.
④working frequency:it supports dual-frequency switching of 108Mhz and 54MHz,and adapts to different speed operation requirements.
⑤Working temperature:wide temperature working condition,stable working temperature range-40℃~85℃,suitable for high and low temperature harsh environment.
⑥package specification:NETSOL MRAM model S3A2004R0M has mainstream 8WSON and 8SOP packages,which are compatible with most ISSI SRAM installation positions and have strong replacement adaptability.
