General Description
DeepCover® embedded security solutions cloak sensitive
data under multiple layers of advanced physical security
to provide the most secure key storage possible.
The MAX66301 DeepCover secure authenticator combines
a highly integrated RFID reader for contactless communication
at 13.56MHz and a SHA-3 secure authenticator
coprocessor. The RFID IC reader covers both 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.
