Adoption of FeRAM in Wireless Power Supply Sensing ICs：
Innovative IoT Sensor Logging Made Possible by Japan's Only FeRAM Manufacturer
Wireless-powered sensing ICs require no batteries or wiring, reduce environmental impact, and eliminate the need for maintenance, while FeRAM reduces the risk of data loss even when the power supply is unstable, suppresses the effects of power fluctuations in external devices, and ensures stable operation.

What is a Wireless Power Supply Sensing IC?
Sensing ICs are ICs that process data from various sensors such as temperature, humidity, pressure, and acceleration, and transfer the data to host devices. In recent years, ICs have been used in a wide range of fields, including smart homes, smart buildings, wearables, medicine, factory line management, automobiles, agriculture, and logistics. In recent years, demand for battery-free, wirelessly powered sensing ICs has been increasing due to their environmental friendliness and ease of maintenance.
Wireless-powered sensing ICs are characterized by the fact that they are not equipped with batteries, but rather use radio waves from a wireless reader/writer or weak power from environmental power generation to activate the power supply at high speed to feed power to the sensor, acquire sensor data, and transfer it wirelessly. No batteries or wiring are required, making it environmentally friendly and economical.
Advantages of FeRAM
Wireless power supply and environmental power generation can cause sensor data to be lost if the power supply is unstable. Since our FeRAM consumes less power when writing than EEPROM or flash memory, acquired sensor data can be digitally converted by ADC and written into FeRAM, which can then be read back wirelessly at once when the communication environment is stable.
In addition, load fluctuations of external devices may cause a drop in power supply to the IC, affecting its operation. Power supply control circuits that are less susceptible to power supply fluctuations and on-chip ferro capacitors with large capacitance per unit area provide a stable power supply and prevent effects on IC operation.
Analog front end (AFE) is available for each sensor interface, including capacitive, resistive, voltage, and current types.
