Device Overview

Summary

The Microchip ATECC608A-TCSM is a secure element part of the Trust Platform for the CryptoAuthentication family. The device 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. 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-TCSM offers 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 a high quality Random Number Generator, 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-TCSM 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.

To start prototyping, please purchase a blank ATECC608A with the desired package and start coding using CryptoAuthLib Library
