Product Details
ATECC608A-SSHDA-T - Secure Authentication & Cryptographic Coprocessor (I²C, SOIC-8)
ATECC608A-SSHDA-T is a high-security cryptographic authentication device from Microchip Technology, designed for IoT device protection, secure key storage, and hardware-based encryption. It integrates advanced security features including ECC (Elliptic Curve Cryptography), secure key storage, and tamper-resistant hardware.
This page is written for product identification and engineering selection guidance. Always verify final limits using the manufacturer's latest datasheet revision for design sign-off.
Overview
ATECC608A-SSHDA-T is a dedicated hardware security IC that enables strong authentication and encrypted communication in embedded systems. Unlike software-based security implementations, it stores cryptographic keys securely within the device, preventing exposure to firmware-level attacks.
This device supports modern security standards including ECDSA, ECDH, and secure boot capabilities, making it highly suitable for connected systems such as IoT endpoints, industrial controllers, and smart devices requiring secure identity verification. Its I²C interface allows easy integration with microcontrollers.
Key Advantages
Keys are stored internally and never exposed, reducing risk of firmware extraction or cloning.
Supports ECC algorithms such as ECDSA and ECDH for authentication and secure communication.
Designed for connected devices requiring secure identity, cloud authentication, and data integrity.
Suitable for battery-powered systems with minimal power overhead during cryptographic operations.
Feature Summary
Hardware acceleration for ECDSA (signature) and ECDH (key exchange).
Configurable zones for private keys, certificates, and secrets.
Simple communication with host MCU, suitable for embedded designs.
Includes countermeasures against physical attacks and unauthorized access.
Package & Footprint
The ATECC608A-SSHDA-T is available in an 8-pin SOIC surface-mount package, suitable for standard PCB assembly processes and industrial-grade applications.
- Place the device close to the MCU to minimize I²C signal integrity issues.
- Ensure proper decoupling capacitor placement for stable operation during cryptographic activity.
- Avoid exposing traces carrying sensitive signals to reduce attack surface.
Note: Use the official datasheet for exact dimensions and recommended land pattern.
