Overview

The ATECC608C is a high-security cryptographic co-processor that provides hardware-based key storage for asymmetric sign, verify, and key agreement operations. It is designed to protect sensitive data and prevent private key exposure through a dedicated secure EEPROM and hardware-accelerated algorithms including ECC and ECDH.

Why Choose This Part

This device features a high-quality NIST SP 800-90A/B/C random number generator and a unique 72-bit serial number for device tracking. It operates over a wide voltage range of 2.0V to 5.5V with a low sleep current of 150uA, making it ideal for battery-powered applications requiring robust security.

Applications

IoT Device Authentication
Ensures only authorized devices can connect to cloud services like AWS IoT or Google Cloud IoT Core using hardware-backed certificates.
Secure Boot
Validates the signature of firmware images during the boot process to prevent the execution of malicious or unauthorized code.
Ecosystem Control
Protects against counterfeit accessories by requiring hardware-based authentication before allowing third-party peripherals to function.
Key Agreement
Facilitates secure communication channels using Elliptic Curve Diffie-Hellman (ECDH) to establish shared secret keys without transmitting them.

Getting Started

Engineers can evaluate this part using the Microchip Trust Platform and the CryptoAuthLib library, which provides a standard API for interfacing via I2C or Single-Wire Interface (SWI). Development boards like the DT100104 (CryptoAuth Trust Platform) provide a plug-and-play experience for rapid prototyping.

Also Consider

ATECC608B MCHPMicrochip Technology - The previous generation variant which may be used if existing firmware is specifically validated for the B revision.
