Microchip Technology ATECC508A CryptoAuthentication™ Devices
Microchip ATECC508A CryptoAuthentication™ Devices are crypto engine authentication devices with highly secure hardware-based key storage. The ATECC508A devices come with a flexible command set and include an EEPROM array for storage. Various sections of memory can be restricted and then the configuration can be locked to prevent changes. Typical applications include IoT node security and ID, secure download and boot, ecosystem control, message security, and anti-cloning.
