Device Overview

Summary

The Microchip ATECC608A integrates ECDH (Elliptic Curve Diffie Hellman) security protocol an ultra-secure method to provide key agreement for encryption/decryption, along with ECDSA (Elliptic Curve Digital Signature Algorithm) sign-verify authentication for the Internet of Things (IoT) market including home automation, industrial networking, medical, as well as accessories and consumables authentication and more. In addition, the ATECC608A offer an integrated AES hardware accelerator strengthening hardware based security for LoRaWAN applications and enable secure boot capabilities for very small microcontrollers. 

The ATECC608A is a secure element from the Microchip CryptoAuthenticationTM portfolio with advanced Elliptic Curve Cryptography (ECC) capabilities. With ECDH and ECDSA being built right in, this device is ideal for the rapidly growing IoT market by easily supplying the full range of security such as confidentiality, data integrity, and authentication to systems with MCU or MPUs running encryption/decryption algorithms. Similar to all Microchip CryptoAuthentication products, the new ATECC608A employs ultra-secure hardware-based cryptographic key storage and cryptographic countermeasures which eliminate potential backdoors linked to software weaknesses.

The device is agnostic of any microprocessor (MPU) or microcontroller (MCU) and compatible with Microchip AVR/ARM MCUs or MPUs. As with all CryptoAuthentication devices, the ATECCC608A delivers extremely low-power consumption, requires only a single GPIO over a wide voltage range, and has a tiny form factor making it ideal for a variety of applications that require longer battery life and flexible form factors.

Take a look at the various use cases including :

- Cloud authentication for AWS IoT

- Cloud Authentication for Google Cloud IoT Core

Secure Boot implementation with an ATSAMD21 Cortex-M0+
