32-bit password data protection scheme, enabling control of wireless read-and-write memory access
Semiconductor firm STMicroelectronics has introduced its M24LR64 wireless memory, a dual-interface EEPROM, which the company says has the ability to transmit and receive information from the heart of an application to a smartphone containing NFC technology.
It also transmit and receive information to an industrial RFID (Radio-Frequency Identification) reader, allowing for transactions, data exchange, object identification and tracking to occur rapidly.
ST’s dual-interface EEPROM products also feature a 32-bit password data protection scheme, enabling control of wireless read-and-write memory access.
The M24LR64 features NFC/RFID compatible ISO15693 wireless interface operating at 13.56MHz, low-power wired I2C interface to MCU or chipset, 64-Kbit memory density, and 32-bit password scheme.
A new App called Dual EE, which operates on the Android operating system, delivers full compatibility with M24LR64 wireless memory, the company said.
The app connects an NFC-enabled smartphone to a prototype temperature recorder featuring ST’s unique M24LR64 wireless memory and demonstrates data transfer and storage.
ST’s Memories Division general manager Benoit Rodrigues said the combination of this new Android app and their innovative dual-interface wireless EEPROM memory will allow users to communicate with a wide range of electronic devices via their NFC-enabled smartphones.
Together, the dual-interface EEPROM and Android app provide a launch pad for consumer-tech innovations offering users new types of benefits via NFC, the company said.
ST’s M24LR64 can be connected directly to a wireless antenna as used in an RFID tag to transfer data through the energy in radio waves between the RFID or NFC reader and an electric tag attached to an object, allowing the equipment to be read or updated without being switched on.
