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.
