It will work with 3.3V or 5V power\/logic, so it’s ready to get to work with a range of development boards. Once you ‘lock’ the chip with your details, you can use it for ECDH and AES-128 encrypt\/decrypt\/signing. There’s also hardware support for random number generation, and SHA-256\/HMAC hash functions to greatly speed up a slower micro’s cryptography commands.\u003c\/p\u003e\n\u003cp\u003eTo our surprise, this chip does not have a public datasheet, \u003ca href=\"https:\/\/www.microchip.com\/wwwproducts\/en\/ATECC508A\"\u003ebut it is compatible with the ATECC508 earlier version which does\u003c\/a\u003e, so please refer to that complete datasheet \u003ca href=\"https:\/\/www.microchip.com\/wwwproducts\/en\/ATECC608A\"\u003eas well as the ATECC608 summary sheet\u003c\/a\u003e.
