Replace FM25V20A, Ferroelectric Memory GX85RS2MC for Generator Excitation System

As we all know, ferroelectric memory can be used in generator excitation system. The real-time data recording and parameter display module of the excitation system needs a large-capacity memory that supports power-down preservation, and the ferroelectric memory is used to store switching and analog quantities in case of faults, so as to display and analyze the faults.

Ferroelectric memory has the advantages of high read/write endurance, high speed writing and low power consumption, for example, its write count life can be up to 1 million times, while the EEPROM is only 100,000 times, which is a great advantage in the program that needs real-time data storage. As a result, the device is now widely used in generator excitation systems.

The memory cell of the ferroelectric memory GX85RS2MC can be used for 1,000,000 reads and writes, data retention: 10 years @ 85°C (200 years @ 25°C), and no data loss when the device is powered down. With an operating voltage range of 2.7V to 3.6V and a minimum standby power consumption of only 9 microamps, it is able to instantly save data at low currents to ensure information security in the system. It has a great advantage in the solution of real-time data storage like generator excitation system.

The advantages of ferroelectric memory GX85RS2MC in generator excitation system application are introduced:

1, GX85RS2MC performance is compatible with MB85RS2MT (Fujitsu) and FM25V20A (Cypress), and can be replaced in place;

2, GX85RS2MC maximum power consumption of 5mA, standby current is only 7μA, can effectively reduce the power consumption of the system.

3, GX85RS2MC supports SPI serial interface, maximum 25MHz operating frequency, can meet the system‘s rapid communication needs.

4, GX85RS2MC working environment temperature range is -40 ℃ to 85 ℃, in line with the industrial environment applications.

5、GX85RS2MC adopts SOP8 small package, which saves PCB board design space and facilitates layout.
