MCHPATECC508A-SSHCZ-T
Overview
The ATECC508A is a secure authentication chip that provides hardware-based key storage for IoT and networking applications. It utilizes Elliptic Curve Cryptography (ECC) and the NIST P256 curve to perform high-speed public key infrastructure (PKI) operations. This device acts as a secure element to protect sensitive keys from software vulnerabilities and physical tampering.
Why Choose This Part
It offers extremely low power consumption with a sleep current of only 150nA and supports up to 16 individual key slots. The integrated high-quality FIPS Random Number Generator and internal unique 72-bit serial number provide robust foundations for high-entropy cryptographic protocols.
Applications
Key Specifications
Getting Started
Implementation typically involves the Microchip CryptoAuthLib library, which handles the I2C or Single Wire Interface communication. For rapid prototyping, use the Microchip CryptoAuthentication Starter Kit (ATCRYPTOAUTH-XPRO-B) to interface with common MCU development environments.
