NFC/RFID tag IC includes security, energy harvesting

The MAX66242 DeepCover Secure Authenticator is a transponder IC that combines an RF front-end compatible with ISO/IEC 15693 and ISO 18000-3 Mode 1, an I² C front-end, a FIPS 180-based SHA-256 security engine, and 4 Kbits of user EEPROM. A bidirectional security model enforces two-way authentication and the device has a unique 64-bit ID.

When acting as a master, the MAX66242 can gather information from a connected sensor or peripheral device and relay its data via the RF port. When acting as a slave, it can serve as an intermediary between a connected host and an RF reader. The IC can harvest energy from an active RF field and has a configurable supply output that can deliver up to 5 mA. It runs from a 3.3-V supply.
