Overview

The ATECC608C-MAVDA-S is a secure element from Microchip's CryptoAuthentication family designed for hardware-based key storage and cryptographic acceleration. It provides a robust defense against physical attacks with a high-quality NIST-compliant random number generator and support for ECDSA, ECDH, and SHA-256 protocols. This version is supplied in a compact 8-pad UDFN package and supports communication via I2C and Single Wire Interface.

Why Choose This Part

It offers ultra-low power consumption with a 3uA sleep current and supports a wide supply voltage range of 2.0V to 5.5V. The device features hardware-based isolated key storage that is resilient against side-channel attacks, providing much higher security than software-based crypto implementations on standard MCUs.

Applications

IoT Device Authentication
Securely authenticates remote IoT nodes to cloud services like AWS IoT or Google Cloud IoT Core using hardware-based ECC keys.
Ecosystem Control
Verifies the authenticity of peripherals or accessories to prevent the use of counterfeit or unauthorized hardware.
Secure Boot Validation
Assists a host microcontroller in verifying the signature of firmware images before execution to ensure system integrity.
Key Agreement
Facilitates Elliptic Curve Diffie-Hellman (ECDH) for establishing encrypted communication channels without exposing private keys.

Key Specifications

Mounting Type Surface Mount
Package / Case 8-UFDFN Exposed Pad
Supplier Device Package 8-UDFN (2x3)

Getting Started

Developers should use the Microchip Trust Platform and the CryptoAuthLib library to integrate the chip into their firmware. The Microchip DM320118 (Trust Platform Development Kit) is a primary hardware tool for prototyping and pre-provisioning workflows.
