Product Details
ATECC608B-MAHDA-T - Microchip CryptoAuthentication™ IC with ECC Support (UDFN-8)
The ATECC608B-MAHDA-T is a high-security CryptoAuthentication™ device from Microchip Technology. It integrates advanced Elliptic Curve Cryptography (ECC) to provide a robust hardware-based root-of-trust. Housed in a compact UDFN-8 package, it is designed for secure key storage, identity authentication, and encrypted communication in IoT, industrial, and automotive ecosystems.
Product Focus: This version features a space-efficient UDFN-8 (2x3mm) footprint, optimized for high-density PCB designs where both security and board space are critical.
Product Overview
The ATECC608B-MAHDA-T is designed to protect intellectual property and ensure platform integrity by providing secure key storage and cryptographic services. Unlike software-based solutions, the ATECC608B utilizes dedicated hardware to perform intensive ECC operations, ensuring private keys are shielded from unauthorized access.
The device includes a high-quality Random Number Generator (RNG) and supports secure boot, message authentication, and TLS-based cloud connectivity, making it an essential component for protecting connected devices from modern cyber threats.
About Microchip Technology
