Datasheet

Ineltek UK has released the latest member of Atmel’s CryptoAuthentication product line, the ATECC508A. This is the first 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.

ATECC508A supports all three pillars of security – Confidentiality, Integrity and Authentication – the “CIA” of secure systems:

Confidentiality – Store confidential keys, secrets, certificates etc. on chip in the most secure form or storage: hardware
Integrity – Use ECDH key agreement with MPU/MCUs running AES via AES-CCM and AES-GCM mechanisms to confirm data integrity
Authentication – Validate code loaded at boot time easily using ATECC508A ECDSA (Elliptic Curve Digital Signature Algorithm) to ensure authenticity

ATECC508A is compatible with any processor including Atmel SMART and Atmel AVR MCUs or MPUs, delivering extremely low-power consumption and requiring only a single GPIO over a wide voltage range. The part is available in 8-pad UFDN, 8-lead SOIC or 3-lead CONTACT packages, making it ideal for a variety of applications including those that require longer battery life and flexible form factors.
