GXSC Ferroelectric Memory GX85RS128 Replaces MB85RS128/FM25V01, High-Reliability Solution for High-Power Power Supplies

From industrial automation production lines to data center power supply systems, high-power power supplies must continuously and stably output electrical energy to meet the stringent demands of various loads. In this complex system, accurate data storage and rapid data retrieval are critical for real-time monitoring, control, and fault diagnosis of the power supply. In industrial high-power power supplies (such as inverters and servo drives), the parameter storage system faces three core challenges:

Millions of frequent writes (real-time saving of voltage/current calibration data)

Zero-delay saving (preventing parameter loss due to sudden power outages)

High-temperature stability (10 years of data retention at 85°C)

Given these storage requirements, the stability, reliability, and efficiency of the GXSC ferroelectric memory GX85RS128 can serve as a critical foundation for achieving these functions. The performance of the GX85RS128 is comparable to that of Fujitsu‘s MB85RS128 and Cypress‘s FM25V01, offering a new storage solution for this field.

Performance Analysis of the GXSC Ferroelectric Memory GX85RS128

1. High-reliability design ensures data security

The GX85RS128 employs advanced ferroelectric process technology and silicon gate CMOS process technology in its non-volatile storage units. These storage units can withstand 1E6 read/write operations, demonstrating exceptional durability and significantly reducing the risk of data storage failures caused by frequent read/write operations. In the face of abnormal conditions such as voltage fluctuations and current surges during high-power power supply operations, the GX85RS128 effectively maintains data integrity and accuracy.

2. High-speed read/write performance meets real-time requirements  

This ferroelectric memory operates at a frequency of up to 25MHz and supports 40MHz high-speed read commands, offering ultra-high-speed read/write performance. During real-time monitoring and control of high-power power supplies, it can quickly store power supply operation data such as voltage, current, and power parameters into the memory and rapidly retrieve them when the control system requires, enabling real-time feedback and precise control of the power supply status.

3. Stable operation over a wide temperature range  

The GX85RS128 operates within an environmental temperature range of -40°C to 85°C, making it suitable for the harsh temperature conditions encountered in high-power power supply environments. Whether in outdoor power equipment in hot tropical regions or power supply facilities in cold polar regions, it maintains excellent electrical performance, ensuring reliable data storage and retrieval, and providing robust support for the stable operation of high-power power supplies under varying temperature conditions.

4. Low power consumption reduces system energy consumption

Unlike traditional flash memory with limited erase/write cycles, ferroelectric memory theoretically offers nearly unlimited erase/write capabilities, effectively extending the lifespan of switches and reducing maintenance costs caused by storage device damage. Additionally, the SF25C20 consumes extremely low power during operation, only 4.2 milliamps, and 9 microamps in standby mode. This low-power design is of significant importance for high-power power supply systems, as it effectively extends the service life of energy storage components such as batteries in power supply equipment.
