MAX66240：DeepCover Secure Authenticator with ISO 15693, SHA-256, and 4Kb User EEPROM
Industry's First SHA-256 Symmetric Key-Based Authenticator
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 (MAX66240) is a
transponder IC that combines an ISO/IEC 15693 and ISO
18000-3 Mode 1-compatible RF front-end, 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
MAX66240. 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.
