FRAM GX85RS2MC replaces FM25V20A/MB85RS2MT for power DTU (data terminal unit) application

Power DTU is one of the devices deployed in distribution substations or switch stations, mainly used for power distribution automation systems. It is installed in switch stations, ring main units, small substations, and other locations. Its main function is to collect real-time data on current, voltage, power, etc., and monitor the operating status of equipment such as circuit breakers and isolation switches; And communicate with the main station through optical fiber or wireless network to achieve remote control, remote monitoring and control.  

The power DTU supports multiple communication interfaces, such as 4G, LoRa, Ethernet, etc., and has data caching and breakpoint resume functions to ensure communication reliability; The 2M FRAM GX85RS2MC of GXSC is a non-volatile memory based on ferroelectric materials, with compatible performance to replace FM25V20A and MB85RS2MT, providing technical advantages such as safety, efficiency, reliability, and low consumption for power DTUs. 

Power DTUs need to frequently store two types of critical data: real-time data collection and fault event data. When traditional volatile memory (such as SRAM) is used, data will be lost immediately after power failure; The erase and write life of EEPROM is only 100000 times, while GX85RS2MC can support up to 1E11 read/write operations, with read/write durability far exceeding traditional SRAM and EEPROM, significantly reducing update time. And it supports 40MHz high-speed read commands, which can quickly respond to data read requests, greatly improving the data reading speed of power DTUs.

The GX85RS2MC chip has excellent data retention capability, and can maintain data for 10 years in a high temperature environment of 85 ℃; At a room temperature of 25 ℃, the data retention time is as long as 200 years. The power DTU data requires long-term stability, and the stable data retention feature of GX85RS2MC ensures that the data stored by the device throughout its entire lifecycle will not be lost or damaged.

Summary: FRAM GX85RS2MC is a 100% domestic supply chain with stable delivery times. GXSCFRAM has good compatibility and can provide SPI and IIC interfaces, making it easy to integrate with other hardware devices in the system. This enables system developers to easily embed FRAM into the system, reducing the complexity and time cost of system development.
