Overview

The ATECC608A-MAHDA-T is a secure element from Microchip Technology designed to provide hardware-based key storage and cryptographic acceleration. It protects sensitive data by offloading intensive cryptographic tasks from the main MCU while providing high-endurance monotonic counters and a high-quality NIST-compliant random number generator. The device communicates over I2C or a Single-Wire Interface and operates across a wide 2V to 5.5V supply range.

Why Choose This Part

This component features protected storage for up to 16 keys or certificates and consumes only 150uA in sleep mode, making it ideal for battery-powered designs. The integrated NIST SP 800-90A/B/C RNG and hardware support for symmetric and asymmetric algorithms provide robust security that is difficult to replicate in software alone.

Applications

IoT Device Authentication
Securely authenticates IoT nodes to cloud services like AWS or Azure using hardware-stored private keys.
Secure Boot
Validates the digital signature of the main MCU firmware before execution to prevent unauthorized code injection.
Counterfeit Protection
Uses unique serial numbers and hardware challenges to verify the authenticity of peripherals or disposable accessories.
Message Encryption
Performs asymmetric sign, verify, and key agreement operations to secure data transmission without exposing secrets to host memory.
