 CEC1702 is a full-featured ARM® Cortex®-M4-based microcontroller with a complete hardware cryptography-enabled solution in a single package that enables secure boot of system firmware. This low-power but powerful, programmable 32-bit microcontroller protects secrets with encryption and validates firmware has been digitally signed and untouched using public key cryptography. 

The device provides significant performance improvements when compared to firmware-based solutions. Its hardware cryptographic cipher suite reduces compute time by orders of magnitude over software solutions, and, as an example, provides 20x-50x performance improvement for PKE acceleration as well as 100x improvement for encryption/decryption. This robust hardware-based feature set results in applications that can run security measures quickly, effectively and with significantly lower cost and power consumption.
