1 Hardware Overview

The CryptoAuth Trust Manager consists of a Microchip SAM D21 microcontroller configured as the main MCU. It comes pre-programmed with Microchip`s Secure Computing Group (SCG) kit protocol. This protocol facilitates the communication between the CryptoAuthentication device(s) and the host MCU over the USB HID interface. The data transfer between the secure element(s) and the host MCU is indicated by the Status LED.

The Trust Manager has one secure element: ECC608-TMNGTLS.
