MCHPATECC608B-SSHDA-B
Overview
The ATECC608B-SSHDA-B is a high-security cryptographic co-processor that provides hardware-based key storage for up to 16 keys. It integrates multiple hardware accelerators for ECDSA, ECDH, and AES-128, allowing for secure authentication and encryption in resource-constrained embedded systems. This secure element is designed to protect sensitive data from physical and logical attacks while offloading intensive cryptographic math from the host MCU.
Why Choose This Part
This device features an extremely low sleep current of 0.15uA and supports a wide supply voltage range from 2V to 5.5V, making it ideal for battery-powered applications. It includes a high-quality NIST-compliant internal random number generator and specialized hardware for HKDF calculation, ensuring robust TLS 1.2 and 1.3 implementation.
