Device Overview

Summary

The Microchip ATECC608A-TFLXTLS is the TrustFLEX secure element part of the Trust Platform for the CryptoAuthentication family. The device comes pre-configured implementing the most common authentication use cases use in the embedded industry by default. It will help the architect accelerating his development time. The configuration is locked in the device and cannot be changed. The cloud infrastructure, either it's a public of private network, can implement either token-base authentication or customer certificate authentication (traditional PKI model). This secure element  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, retail or any TLS connected networks. Other important features integrated in the ATECC608A-TFLXTLS are the AES128 hardware accelerator and 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 virtually any MCUs or MPUs thanks to the CryptoAuthLib library. As with all CryptoAuthentication devices, the ATECCC608A-TFLXTLS 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.
The ATECC608A-TFLXTLS comes also provisioned with default thumbprint certificates and key that are unlocked in the device and changeable by the customer own credentials (differently than the ATECC608A Trust&GO). It helps providing the flexibility to the customer to implement its own certificate chain. Take a look at the various code examples including :

Cloud authentication for AWS IoT (32-bit MCU)
Cloud Authentication for AWS IoT Greengrass (Linux)
- Cloud Authentication for Microsoft Azure (32-bit MCU) - coming soon
TLS network authentication with third party stacks
