FRAM GX85RS2MC in Smart Distribution Box compatible with MB85RS2MT

As an instrument for measuring electricity consumption, the accuracy of the meter is not only related to the accuracy of the detection chip, but also to its storage method. If the detected electricity data can not be randomly written into the memory or if there is an error in the process of writing into the memory, the accuracy of the meter will be greatly reduced.

Based on the characteristics of FRAM GX85RS2MC (MB85RS2MT), the design of the power storage scheme of the traditional meter will be reformed. Since the read/write count of GX85RS2MC is 1 million times, the MCU can write into FRAM when it detects a pulse, and the data will not be lost after the power down because the power data is written into FRAM in real time.

FRAM GX85RS2MC application features:

1, GX85RS2MC through the ferroelectric process and silicon gate CMOS process technology to form a non-volatile memory cell, the chip does not need a battery to maintain data.

2, GX85RS2MC capacity 2M bit, provide SPI interface, operating frequency 25 megahertz, and support 40MHz high-speed read command.

3, GX85RS2MC operating ambient temperature range -40 ℃ to 85 ℃, the package is an 8-pin SOP package, RoHS compliant; performance compatible with MB85RS2MT (Fujitsu) and FM25V20A (Cypress).

4. The GX85RS2MC has a minimum power consumption of 9 microamps (standby), an operating voltage of 2.7 volts to 3.6 volts, and can be operated over a temperature range of -40°C to 85°C.

Using GX85RS2MC (MB85RS2MT) memory power data storage system, can make the power metering system is very accurate, reduces power consumption, and has a compact structure, fewer interface lines, simple control, strong anti-interference ability, higher communication rate, flexible expansion and many other advantages.
