Overview

The ATECC608C-MAHCZ-S is a secure element from Microchip Technology designed to provide hardware-based cryptographic storage and execution. It integrates ECDSA sign-verify capabilities, ECDH key agreement, and AES-128 hardware acceleration to protect sensitive keys from physical and logical attacks. This low-power co-processor offloads intensive cryptographic tasks from the host MCU while consuming only 30 uA in sleep mode.

Why Choose This Part

This device features a high-quality NIST SP 800-90A/B/C random number generator and secure hardware key storage that is resistant to side-channel attacks. It supports both I2C and a Single Wire Interface (SWI), allowing for flexible integration even in pin-constrained designs while operating across a wide 2V to 5.5V supply range.

Applications

IoT Device Authentication
Securely storing unique private keys for mutual authentication with cloud platforms like AWS IoT and Google Cloud IoT Core.
Secure Boot
Validating firmware signatures using ECDSA P-256 to ensure only authorized code executes on the host microcontroller.
Ecosystem Protection
Verifying the authenticity of peripherals or disposables to prevent third-party clones from working with a proprietary system.
Message Encryption
Utilizing integrated AES-128 and SHA-256 hardware engines for high-speed data encryption and integrity checks in constrained systems.

Getting Started

Developers can evaluate this chip using the CryptoAuth Trust Platform development kits and Microchip's Trust Platform Design Suite software. Practical implementation is supported by the CryptoAuthentication Library (CAL), which provides a standard API for interfacing with the ATECC608C over I2C or SWI.

Also Consider

ATECC608B-SSHCZ-B MCHPMicrochip Technology - An older iteration in an 8-lead SOIC package for designs that prefer larger footprints over the UDFN package.
DS28E15P+ Maxim Integrated / Analog Devices - A simpler SHA-256 based authentication IC for applications that do not require asymmetric ECC capabilities.
