Compatible with FM25V01, FRAM GX85RS128 for Smart Gateway Applications

The normal operation of the smart gateway depends on various configuration parameters, such as network address, routing table, security policy, etc., which requires a kind of non-volatile memory to save the configuration information, and the smart gateway needs to monitor its own status and the status of the connected devices in real time, such as the connection status of the devices, operation time, fault information, etc. The non-volatile memory ensures that these configuration information will not be lost after the power failure. The non-volatile nature of the ferroelectric memory ensures that this configuration information will not be lost after the smart gateway is powered off, and that the smart gateway will be able to quickly return to its previous state of operation the next time it is powered on, without having to be reconfigured.

Ferroelectric memory GX85RS128 applied to the smart gateway can enhance the system‘s data storage and backup capabilities, the core technology is the ferroelectric process and silicon gate CMOS process technology to form a non-volatile storage unit, the number of erasure and writing times can be up to 1,000,000 times, and the data can be maintained for 10 years @ 85 ° C (200 years @ 25 ° C), which is capable of stably storing the data in these harsh environments. Compared to other types of memory, such as flash memory or EEPROM, ferroelectric memory has an advantage in terms of reliability of data retention.

With an operating voltage range of 2.7V to 3.6V and a minimum standby power consumption of only 9 microamps, the GX85RS128 can reliably store data without delay at low currents, preventing data loss after a power down. The chip can PIN TO PIN replace Fujitsu MB85RS128 and Cypress FM25V01 with the same excellent performance at an advantageous price.
