FRAM GX85RS2MC Based Microcontroller for Wireless Sensor Network Applications

Wireless Sensor Networks collect more data through sensors in real time and update them remotely, however, general microcontroller technology, sensor power supply issues and Flash memory erase counts are difficult to meet these applications. This paper mainly mentions FRAM GX85RS2MC to solve the problems of sensor data storage and microcontroller technology.

Ordinary microcontrollers generally use Flash and EEPROM storage, FRAM GX85RS2MC based microcontrollers can ensure 100 times faster data writing and 250 times lower power consumption. Power consumption is also effectively reduced when executing code from ferroelectric memory.FRAM can be erased and written up to one million times, which is virtually unlimited for many applications.

The core technology of the GXSC GX85RS2MC is a ferroelectric process and silicon gate CMOS process technology to form a non-volatile memory cell. With an operating voltage range of 2.7V to 3.6V and a minimum standby power consumption of only 9 µA, it can store data reliably and without delay at low current, preventing data loss after power down. In addition, the GX85RS2MC is a non-volatile memory that provides data retention capability in all power modes. With FRAM, there is no need for a separate EEPROM and SRAM that relies on battery power.
