ATECC608B-MAHCZ-S   – MICROCHIP

The Microchip Technology ATECC608B-MAHCZ-S is a CryptoAuthentication™ device integrating Elliptic Curve Diffie-Hellman (ECDH) and Elliptic Curve Digital Signature Algorithm (ECDSA) cryptographic functions with a secure hardware key storage. Specifically configured for secure boot and secure storage applications, it provides a robust solution for authentication and secure communication. The device features a guaranteed unique 72-bit serial number and secure storage for up to 16 keys. Its low-power consumption and small footprint make it ideal for embedded systems. The ATECC608B-MAHCZ-S operates within a typical voltage range of 2.0V to 5.5V, delivering a maximum output current rating of 15mA. It comes in an 8-pad UDFN package, suitable for surface mount device (SMD) assembly. This component is designed to operate reliably across an industrial operating temperature range of –40°C to 85°C. Its inherent resistance to physical attacks and side-channel analysis offers a significant advantage over software-based security solutions, enhancing the overall security posture of IoT devices and embedded systems.
