Overview

The Secure 3 Click Board™ carries the ATSHA204A, a cryptographic coprocessor with secure hardware-based key storage from Microchip. The Click Board™ is designed to run on either 3.3V or 5V power supply. Secure 3 Click Board™ communicates with the target microcontroller over an I2C interface.

NOTE: The Secure 3 Click Board™ comes with stacking headers which allow you to combine it with other Click Boards™ more easily by using just one mikroBUS socket.

The Secure 3 Click Board™ carries the ATSHA204A, a cryptographic coprocessor with secure hardware-based key storage from Microchip. The click is designed to run on either 3.3V or 5V power supply. The Secure 3 Click Board™ communicates with the target microcontroller over an I2C interface.

It is ideal to use for:

  • Secure download and boot - authentication and protect code in-transit
  • Ecosystem control - ensure only OEM/licensed nodes and accessories work
  • Anti-cloning - prevent building with identical BOM or stolen code
  • Message security - authentication, message integrity, and confidentiality of network nodes (IoT)

NOTE: The Secure 3 Click Board™ comes with stacking headers which allow you to combine it with other clicks more easily by using just one mikroBUS™ socket.

ATSHA204A Features

The ATSHA204A is a member of the Microchip CryptoAuthentication™ family of high-security hardware authentication devices, which uses Secure Hash Algorithm (SHA-256) with 256-bit key length, message authentication code (MAC) and hash-based message authentication code (HMAC) options. It has a flexible command set that allows use in many applications.

MikroE Storage Secure 3 click

The ATSHA204A device includes an Electrically Erasable Programmable Read-Only Memory (EEPROM) array that can be used for key storage, miscellaneous read/write data, read-only, secret data, consumption logging, and security configuration. Access to the various sections of memory can be restricted in a variety of ways, and the configuration can then be locked to prevent changes.
