Analog Devices / Maxim Integrated MAX66301 DeepCover Secure Authenticators

Analog Devices MAX66301 DeepCover Secure Authenticators combines a highly integrated RFID reader and an SHA-3 secure authenticator coprocessor. The Analog Devices RFID IC reader covers the ISO 14443 Type A and ISO 15693 standards. The authenticator coprocessor's engine is based on the FIPS 202 standard and supports secure challenge-and-response authentication when paired with peripherals such as the MAX66250 transponder. An embedded host processor can easily interface with the MAX66301 using its UART or SPI interface.
