Microchip Technology, Inc. Specialized ICs ATECC608B-SSHCZ-B

The ATECC608B-SSHCZ-B is a cryptographic co-processor designed for secure hardware-based key storage, capable of protecting up to 16 keys, certificates, or data. It supports various cryptographic operations, including asymmetric signing and verification through ECDSA and ECDH, as well as symmetric algorithms like SHA-256 and AES-128. The device features a high-quality random number generator and two high-endurance monotonic counters, enhancing its security capabilities. This IC offers two interface options: a high-speed single wire interface and a standard I¬=C interface, with operating voltage levels ranging from 1.8V to 5.5V. It is available in multiple packaging options, including an 8-lead SOIC and an 8-pad UDFN, and supports both standard and extended industrial temperature ranges from -40¬8C to +85¬8C and -40¬8C to +100¬8C, respectively. The device is suitable for applications in IoT network endpoint key management, secure boot, and encryption of small messages and personally identifiable information (PII). With a low sleep current of less than 150 nA, the ATECC608B-SSHCZ-B is efficient for power-sensitive applications.
