MAX66242 Datasheet | Maxim Integrated

Description Deep Cover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible. The Deep Cover Secure Authenticator (MAX66242) is a transponder IC that bines an ISO/IEC 15693 and ISO 18000-3 Mode 1-patible RF front-end, an I2C frontend, a FIPS 180-based SHA-256 engine and 4096 bits of user EEPROM in a single chip. A bidirectional security model enforces two-way authentication between a host system and the MAX66242. Each device has its own guaranteed unique 64-bit ROM ID that is factory programmed into the chip. This ROM ID is used as a fundamental input parameter for cryptographic operations and serves as an electronic serial number within the application. In addition to the RF interface, the MAX66242 also has an I2C interface, which can operate as a slave or master port. 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, the device can serve as an intermediary between a connected host and an RF reader. The MAX66242 can harvest energy from an active RF field. The configurable supply output can deliver up to 5m A given adequate field strength.
