Smart meters transmit power data through various wired and wireless networks,enabling power companies to monitor power consumption in real time and accurately.With the help of these real-time data,power companies can effectively monitor consumption and quickly identify anomalies,thus optimizing operational efficiency and reducing costs.Because smart meters need to record data continuously,high durability and high reliability memory is the key.At the same time,with the popularization of OTA(over the air upgrade)function,the fast writing ability of memory is becoming more and more important.
The
MRAM memory introduced by Yingshang Microelectronics,with its excellent performance,has become an ideal choice to meet the high durability and high-speed writing requirements of smart meters.It can not only replace the traditional NOR Flash,FeRAM and nvSRAM,but also has excellent non-volatile characteristics and longer service life.MRAM provides a variety of capacity specifications,which can fully cover the different storage requirements of smart meters and realize complete recording and accurate management of power data.
Key parameters of MRAM memory:
①Capacity range:1Mb,2Mb,4Mb,8Mb,16Mb,32Mb and 64Mb.
②Power supply voltage:1.8V(1.71V~1.98V)or 3.3V(2.7V~3.6V).
③Interface type:MRAM memory supports single wire,double wire and four wire SPI,and is compatible with SDR and DDR modes.
④Built-in error correction mechanism:MRAM memory does not need external ECC.
⑤Packaging forms:8WSON,8SOP,16SOP,24FBGA,in line with industrial standards.
Core advantages of MRAM memory:
①High-speed reading and writing performance:greatly improve the efficiency of data writing and reading.
②Almost infinite durability:MRAM memory supports up to 100 million write cycles,far exceeding traditional memory.
③Byte-level addressing ability:MRAM memory capacity configuration is more flexible and software management is more efficient.
④Optimizing OTA experience:MRAM memory significantly shortens the program update time and effectively reduces the system power consumption.
⑤Power failure data security:recover quickly in case of sudden power failure to ensure data integrity.
⑥Persistent storage of data:The data can be kept for more than 10 years after power failure.
