Crypto Acceleration Unit (CAU) and MmCAU Software Library

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.

Software Details

Features

  • CAU is present in ColdFire+®/ColdFire+
  • mmCAU is present in Kinetis® Cortex M4
  • Supports AES128, AES192, AES256, DES, 3DES, MD5, SHA-1, and SHA-256 (only for CAU version 2 and mmCAU) algorithms
  • Simple, flexible programming model
  • Ability to send up to three commands in one data write operation (Only for mmCAU)
  • Optimized, callable C-function library that provides the appropriate software building blocks to implement higher-level security functions
