Ferroelectric memory GX85RS2MC in motor control applications, compatible with MB85RS2MT

Ferroelectric memory is very suitable for applications that require high data acquisition and write time to reliably store important information. Its specific applications in motor control such as: in the rotary encoder for storing data; in the servo system for storing MCU data to reduce the MCU storage pressure; in the generator excitation system with magnetoresistive random memory, can be used for large-capacity support for power-down preservation of the memory, storage of switching and analog quantities during the fault for fault display and analysis, etc..

In motor control compared with conventional non-volatile memory such as EEPROM can store and read data quickly to ensure real-time. For example, it can write data at bus speed with no delay waiting after writing, whereas EEPROM typically requires 5 to 10 milliseconds of data writing time after writing. This helps system designers to solve the problem of storing data in real time as well as the problem of data loss in case of sudden power failure. Taking the domestic ferroelectric memory GX85RS2MC as an example, some of its product features are as follows:

- The memory cell of GX85RS2MC can be used for 1,000,000 read/write operations, with a data retention time of 10 years @ 85°C (200 years @ 25°C), and high reliability as data will not be lost when the system is powered down.

- The GX85RS2MC, with a capacity of 2M bit, is made by ferroelectric process and silicon gate CMOS process technology, and can maintain data without battery, which can improve data security.

- With an operating voltage of 2.7V to 3.6V, a maximum power consumption of 5mA, and a standby current of only 7μA, the GX85RS2MC can effectively reduce the power consumption of the system for a wide range of applications.

- GX85RS2MC supports SPI serial interface with maximum 25MHz operating frequency, which can meet the fast communication requirements of the main control chip.

- The GX85RS2MC operates in an ambient temperature range of -40°C to 85°C, which is in line with applications in industrial environments.

- The GX85RS2MC is available in a small SOP8 package, which saves PCB design space and facilitates layout.

- The GX85RS2MC is PIN TO PIN compatible with MB85RS2MT (Fujitsu) and FM25V20A (Cypress).
