By having ST's NFC and EEPROM chips interact via passive RF technology,
Support for reducing power consumption of electronic devices

Interaction between mobile phones and other electronic devices has been enabled through STMicroelectronics ( www.st.com )'s latest secure MCU and non-volatile memory technologies. By equipping all electronic products, such as personal health monitors, TVs, and washing machines, with ST's industry-unique RF-enabled EEPROM memory, data can be wirelessly uploaded and downloaded to mobile phones equipped with ST's NFC chips without using onboard power.

"Sylvain Fidelis, RF Memory Marketing Manager at STMicroelectronics, stated, 'The combination of wireless access non-volatile memory and NFC (Near Field Communication) has brought about a major change, enabling users to interact with all types of electronic devices using their mobile phones. As the only company in the industry to supply both NFC and dual-interface EEPROM solutions, ST enables simple, low-power, contactless data exchange in various applications across the medical, consumer electronics, and industrial sectors, such as diagnostics, parameter updates, remote operation, and asset tracking.'"

ST's dual-interface EEPROM utilizes passive RFID technology to wirelessly access parameters stored in electronic devices, thus consuming no onboard power. For example, EEPROMs installed in various types of health monitors store patient information and other important data. This data can be downloaded to a mobile phone equipped with an ISO 15693-supported NFC router, such as ST's ST21NFCA, for viewing, or sent to a doctor for real-time diagnosis. These operations can be performed even when the monitor device is turned off.

By combining NFC with dual-interface EEPROM technology, the programming and operation of various home appliances can be significantly simplified. Users can read tracking information or operation data and transmit it to a service center simply by holding their mobile phone close to a TV receiver or washing machine. Similarly, the service center can reprogram or adjust the device using a code sent to the user's mobile phone.

ST's M24LR64 EEPROM memory integrates both standard digital I2C and passive RF (ISO 15693) interfaces. In RF mode, since the memory receives both energy and data from the system, the
