Application of Ferroelectric Memory GX85RS2MC in Air Volume Monitoring System

The air volume monitoring system is a device that ensures air circulation efficiency, environmental air quality, and safe operation of equipment. The system needs to collect real-time parameters such as wind speed, air volume, and air pressure, record historical data for trend analysis, and store device configuration parameters to ensure normal startup after power failure. At the same time, it needs to adapt to harsh environments such as wide temperature, dust, and electromagnetic interference in industrial sites.

Traditional EEPROM and Flash storage solutions often suffer from problems such as short write life, slow write speed, and poor low-temperature performance. The ferroelectric memory GX85RS2MC is non-volatile and has a near infinite write life, which can ensure the long-term data storage security of the system.

The air volume monitoring system needs to store historical monitoring data and equipment configuration parameters for a long time. The core technology of domestic ferroelectric memory GX85RS2MC is the formation of non-volatile memory cells using ferroelectric process and silicon gate CMOS process technology. Its operating voltage range is 2.7V to 3.6V, with a minimum standby power consumption of only 9 microamperes. It can reliably and without delay store data under low current conditions, allowing the system to retain data even after power failure.

Wide temperature operation and strong anti-interference, suitable for harsh industrial environments: Air volume monitoring systems are often deployed in industrial workshops, outdoor computer rooms, clean rooms, and other environments. The ferroelectric memory GX85RS2MC has excellent data retention capabilities, covering a working temperature range of -40 ℃~85 ℃. In a high temperature environment of 85 ℃, data can be maintained for 10 years; At a room temperature of 25 ℃, the data retention time is as long as 200 years; This stable data retention feature ensures that the data stored in the air volume monitoring system will not be lost or damaged throughout its entire lifecycle.
