Product Description
The Microchip ATECC608A-SSHDA-B is an advanced crypto authentication integrated circuit (IC) designed to deliver robust hardware-based security for industrial, embedded, IoT, networking, and automation applications. Housed in an 8-pin SOIC surface-mount package, this device supports industry-standard Elliptic Curve Diffie - Hellman (ECDH) and Elliptic Curve Digital Signature Algorithm (ECDSA) protocols for cryptographic key agreement and authentication.
With a wide 2V to 5.5V operating range, the ATECC608A-SSHDA-B is engineered for compatibility with a diverse array of microcontrollers and embedded systems. Its secure hardware-based memory architecture can manage and protect up to 16 keys, certificates, or data records, making it ideal for scenarios demanding strong authentication and encrypted data protection.
The device features hardware support for both asymmetric (sign, verify, key agreement) and symmetric cryptographic algorithms. Used extensively in secure boot, code signature validation, and secure communication, it helps to prevent unauthorized device access and on-board attacks in industrial, medical, and industrial networking environments. Internal monotonic counters support consumption tracking, and each IC is assigned a unique 72-bit serial number for identification and traceability.
Operating reliably in demanding environments, the ATECC608A-SSHDA-B functions from -40°C to +85°C, ensuring security even under harsh temperature fluctuations commonly found in field installations.
With its combination of secure storage, cryptographic co-processing, support for modern authentication standards, and hardware-based protection, the Microchip ATECC608A-SSHDA-B is well suited for next-generation industrial control systems, secure networked endpoints, medical electronics, accessory authentication, and commercial embedded designs that require trusted device identity and data integrity.
