Microchip Technology, Inc. Specialized ICs ATECC108A-SSHCZ-B

The ATECC108A-SSHCZ-B is a secure authentication device from Lingto Electronic Limited, designed for applications requiring robust security features. It supports high-speed public key infrastructure (PKI) algorithms, including ECDSA and SHA-256, and offers hardware-based key storage for up to 16 keys. The device includes a guaranteed unique 72-bit serial number and an internal FIPS-compliant random number generator. This IC operates over a supply voltage range of 2.0V to 5.5V and features a low sleep current of less than 150nA. It can communicate via a 1MHz I¬=C interface or a high-speed single-wire interface, allowing for flexible integration into various systems. The ATECC108A also includes intrusion detection capabilities and programmable security configurations, making it suitable for applications such as secure downloads, boot authentication, and anti-cloning measures. The device is packaged in an 8-lead SOIC format and is compatible with existing Atmel CryptoAuthentication products, providing an upgrade path for systems using earlier models. This makes the ATECC108A-SSHCZ-B a versatile choice for engineers looking to enhance the security of their IoT devices and other applications requiring secure authentication.
