Microchip ATECC508A Crypto Products | DigiKey Daily

Microchip's CryptoAuthentication ensures things and code are authentic, untampered, and confidential. The Atmel® ATECC508A features a wide array of defense mechanisms specifically designed to prevent physical attacks on the device itself or logical attacks on the data transmitted between the device and the system. The device has a 10Kb EEPROM memory for keys, certificates, and data, along with hardware acceleration for the NIST standard P256 prime curve. System integration is easy due to a wide supply voltage range of 2.0V to 5.5V and an ultra-low sleep current of <150nA. Each ATECC508A ships with a guaranteed, unique, 72-bit serial number.
