STMicroelectronics N.V. (STMicro) has rolled out a wireless memory that is capable of transmitting and receiving information from an application to an NFC-enabled smartphone or to an RFID reader. The application includes speeding up transactions, data exchange, object identification and tracking. The M24LR64 is suitable to many industrial and consumer applications as demonstrated by Android-based app, Dual EE.

The app delivers full compatibility with STMicro's wireless memory, showing its ability to transfer and store data. These capabilities are easily transferable to medical devices, home appliances, CE products and meters. Adoption of NFC technology and M24LR64 will cut the cord and give users more freedom in saving and exchanging information.

STMicro's M24LR64 is a dual-interface EEPROM that can connect to a wireless antenna and enable a device to transfer, read or updated data without being switched on. The company claims that this is the only product of its type that is able to communicate with RFID and ISO15693-capable NFC readers, as well as the system's own processor. The dual-interface EEPROM products also feature a 32bit password data protection scheme enabling control of wireless read-and-write memory access.


Dual Interface EEPROMs transmit data from the heart of the application to either an NFC smartphone or industrial RFID reader.

NFC is a short-range technology operating at 13.56MHz that is being implemented on smartphones to enable customers to make payments, such as for public transit and in convenience stores, using their mobile devices. Partnerships between major U.S. wireless carriers and credit card companies will drive NFC technology into 30.5 percent of all handsets shipped in 2015, according to market-research firm IHS iSuppli.

Together, the dual-interface EEPROM and Dual EE provide a launch pad for consumer-tech innovations offering users new types of benefits via NFC. The memory can also operate with RFID equipment used in the supply chain. The app can be downloaded free from the Android Market and has been validated on leading smartphones. The source code of the sample application is available on the STMicro's website, giving developers a head start to designing their own Android NFC applications.

M24LR64 is available at $0.72 for 1,000 units. Alternative pricing options are available for large order quantities.
