CAUAP

Roll over image to zoom in

The cryptographic acceleration unit (CAU) is a ColdFire® coprocessor implementing a set of specialized operations in hardware to increase the throughput of software-based encryption and hashing functions.

The Memory-Mapped Cryptographic Acceleration Unit (mmCAU) present in Kinetis® MCUs is a coprocessor that is connected to the processor's private peripheral bus (PPB). It supports the hardware implementation of a set of specialized operations to improve the throughput of software-based security encryption/decryption operations and message digest functions.
