The M5Stack Crypto Authentication Unit (ATECC608B) is a crypto coprocessor with hardware-based secure key storage, integrated with ATECC608B hardware cryptographic chip, using an I2C communication interface.
The chip has a built-in 10Kb EEPROM for storing keys, certificates, data, consumption records, and security configurations. The configuration can be locked to prevent changes by restricting access to memory areas.
