NXP A71CH - Plug and Trust Secure Element

The ready-to-use IoT security IC A71CH for cloud connections from NXP is the fast and easy way to deploy secure IoT connections

NXP A71CH chip image

A71CH is a ready-to-use secure element for IoT devices providing a root of trust at the IC level and delivers, chip-to-cloud security right out of the box, so you can safely connect to IoT clouds and services, including AWS, without writing security code or exposing keys.

Complete product support package

Delivered as a ready-to-use solution, the A71CH includes a complete product support package that simplifies design-in and reduces time-to-market. NXP eases the overall design process in several ways. For example, the use of an OpenSSL engine and integration into mbedTLS makes it easier to work with connectivity stacks.

NXP also offers time-saving design tools like sample code for major use cases, extensive application notes, and compatible development kits for i.MX and Kinetis microcontrollers, which accelerate the final system integration.

OM3710/A71CHARD - A71CH Arduino compatible development kit is also available at Avnet Silica.
