Description
General part information
ATECC508A Series
Recommend starting with the[Trust Platform ATECC608B](https://www.microchip.com/en-us/products/security/trust-platform) (Trust&GO, TrustFLEX, TrustCUSTOM)
The ATECC508A crypto element is the first crypto device to integrate ECDH (Elliptic Curve Diffie–Hellman) key agreement, which makes it easy to add confidentiality (encryption/decryption) to digital systems including Internet of Things (IoT) nodes used in home automation, industrial networking, accessory and consumable authentication, medical, mobile and other applications. In addition to ECDH, the ATECC508A has ECDSA sign-verify capabilities built-in to provide highly secure asymmetric authentication. The combination of ECDH and ECDSA makes the device an ideal way to provide all three pillars of security such as confidentiality, data integrity, and authentication when used with MCU or MPUs running encryption/decryption algorithms (i.e. AES) in software. Similar to all Microchip CryptoAuthentication products, the new ATECC508A employs ultra-secure hardware-based cryptographic key storage and cryptographic countermeasures which are more secure than software-based key storage. This next-generation CryptoAuthentication device is compatible with any microprocessor (MPU) or microcontroller (MCU) including SMART and Microchip AVR MCUs or MPUs. As with all CryptoAuthentication devices, the ATECCC508A delivers extremely low-power consumption, requires only a single GPIO over a wide voltage range, and has a tiny form factor making it ideal for a variety of applications including those that require longer battery life and flexible form factors. The ATECC508A is downward compatible with the ATECC108A, ATECC108, ATSHA204A, and ATSHA204 crypto element devices.
The Microchip ATECC508A integrates ECDH (Elliptic Curve Diffie Hellman) security protocol an ultra-secure method to provide key agreement for encryption/decryption, along with ECDSA (Elliptic Curve Digital Signature Algorithm) sign-verify authentication for the Internet of Things (IoT) market including home automation, industrial networking, accessory and consumable authentication, medical, mobile and more.
