8.6 Cryptographic Accelerator Module (CAM)

The Cryptographic Accelerator Module is designed to reduce CPU workload by accelerating computationally intensive cryptographic operations. The module integrates high-performance symmetric and asymmetric cryptographic accelerators, along with a True Random Number Generator (TRNG) and a dedicated DMA unit into a single module. It can be used for realizing use cases such as secure communication, secure boot, secure firmware upgrade, node authentication or key generation.

The CAM firmware driver and other supporting collateral can be found at www.microchip.com/dspic33a-crypto-accelerator.
