概述

说明

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 (MAX66300) combines a highly integrated RFID reader for contactless communication at 13.56MHz and a SHA-256 secure authenticator coprocessor. The RFID IC reader covers both the ISO 14443 Type A and the ISO 15693 standard. The authenticator coprocessor’s engine is based on the FIPS 180-4 standard and supports secure challenge-and-response authentication when paired with peripherals such as the Maxim MAX66240/ MAX66242 family of tag solutions. An embedded host processor can easily interface with the MAX66300 using its UART or SPI interface.
