DeepCover Secure Authenticator 8-Pin SOIC N T/R

DeepCover embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible. The DeepCover Secure Authenticator (MAX66242ESA+T) is a transponder IC that combines an ISO/IEC 15693 and ISO 18000-3 Mode 1-compatible 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 MAX66242ESA+T. 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 MAX66242ESA+T also has an I²C interface, which can operate as a slave or master port. When acting as a master, the MAX66242ESA+T 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 MAX66242ESA+T can harvest energy from an active RF field. The configurable supply output can deliver up to 5mA given adequate field strength.
