Microchip ECC204 Secure Authentication IC

A key member of the CryptoAuthentication™ family

The ECC204 by Microchip is a member of the CryptoAuthentication™ product family. The device is targeted for disposable and ecosystem control applications and is intended to be used as a companion device with Microchip or other vendors’ microcontrollers.

Microchip recently expanded its secure authentication device portfolio with six new products in its CryptoAuthentication™ and CryptoAutomotive™ IC families that meet Common Criteria Joint Interpretation Library (JIL) High rated secure key storage and support certified algorithms that comply with the Federal Information Processing Standard (FIPS).

This portfolio of secure authentication devices lowers the barrier to entry and enables developers of products for new segments and applications to implement trusted authentication to prevent counterfeiting, improve quality control and safeguard the user experience. As counterfeits become prevalent across many industries, the need to implement embedded trust in many designs is critical.
