MCHPATECC608B-SSHCZ-B
Overview
The ATECC608B-SSHCZ-B is a secure element and cryptographic co-processor designed for hardware-based key storage. It offloads compute-intensive security tasks from the host microcontroller, including ECDSA sign-verify operations and AES-128 symmetric encryption. Operating over a voltage range of 2V to 5.5V, it features an ultra-low sleep current of 150nA for battery-powered applications.
Why Choose This Part
It provides physical protection against side-channel attacks and tampering while supporting both I2C and Single Wire Interfaces. The integrated NIST SP 800-90A/B/C random number generator and high-endurance monotonic counters simplify the implementation of robust security protocols without taxing host MCU resources.
