Equipped with ST’s Near Field Communication (NFC) chip, a mobile phone can upload and download data over the air from equipment fitted with the company’s RF-enabled EEPROM memory, from personal health monitors to TV sets and washing machines, without consuming any on-board power.
For example, in health-monitoring devices, the EEPROMs can store patient information and other important data. With mobile phones that integrate an ISO 15693-capable NFC (Near Field Communications) router, such as the ST21NFCA, it is possible to download the data and either display the information on the handset or send it to the doctor for real-time diagnosis--even when the monitoring device is turned off.
The combination of the NFC and Dual-Interface EEPROM technologies can also simplify programming or servicing of consumer electronics and home appliances. Users just need to place their cellphone close to a TV set or a washing machine to read and send traceability information or operating data to the service center. Similarly, they will be able to re-program or re-calibrate the equipment using a code sent to their phone by the service provider.
The M24LR64 is a dual-interface, electrically erasable programmable memory (EEPROM). It features an I2C interface and a passive radio frequency (ISO 15693) interface and can be operated from a VCC power supply. It is also a contactless memory powered by the received carrier electromagnetic wave. In RF mode, the memory requires no power as it gathers both the energy and the data from the system. This enables on-board energy savings and provides a convenient way to remotely program or update electronic products.
ST’s ST21NFCA solution integrates all the necessary hardware and software for a complete NFC system, supporting all existing contactless standards for proximity and vicinity, including the ISO 15693 RF technology.
