EVALUATION KIT AVAILABLE ABRIDGED DATA SHEET MAX66242 DeepCover Secure Authenticator with 2 ISO 15693, I C, SHA-256, and 4Kb User EEPROM General Description Benefits and Features DeepCover embedded security solutions cloak sensitive Complete Counterfeit/Cloning/IP Protection Engine SHA-256 Engine Runs a Symmetric Key-Based data under multiple layers of advanced physical security to provide the most secure key storage possible. Bidirectional Secure Authentication Strong Authentication Achieved with a High Bit Count, The DeepCover Secure Authenticator (MAX66242) is a User-Programmable Secret, and Input Challenge transponder IC that combines an ISO/IEC 15693 and ISO Batteryless RF Communication 2 18000-3 Mode 1-compatible RF front-end, an I C front- 4096 Bits of User EEPROM with User-Programmable end, a FIPS 180-based SHA-256 engine and 4096 bits Memory of user EEPROM in a single chip. A bidirectional security Memory R/W Protection Options Including OTP/ model enforces two-way authentication between a host EPROM Emulation Mode system and the MAX66242. Each device has its own guar- Unique Factory-Programmed 64-Bit Identification anteed unique 64-bit ROM ID that is factory programmed Number into the chip. This ROM ID is used as a fundamental input Integrated 32-Byte SRAM Buffer Enables Faster parameter for cryptographic operations and serves as an 2 HF-to-I C Transactions electronic serial number within the application. Flexible Connection and Communication Capabilities In addition to the RF interface, the MAX66242 also has an 2 Support a Wide Range of Applications I C interface, which can operate as a slave or master port. Programmable I/O (PIO) Can Be Configured as a When acting as a master, the MAX66242 can gather infor- Wake-Up or Monitoring/Control Signal mation from a connected sensor or peripheral device and HF Standards ISO/IEC 15693 and 18000-3 MODE1 relay its data via the RF port. When acting as a slave, the Compatible (13.56 MHz 7kHz Carrier Frequency) device can serve as an intermediary between a connected 2 I C InterfaceMaster/Slave Port Eliminates Host host and an RF reader. The MAX66242 can harvest ener- Microcontroller for Sensor-Tag Applications gy from an active RF field.
