About the Processor

The Cortex-M33 processor has a low gate count, it is very energy-efficient and is

intended for microcontroller and deeply embedded applications. The processor is

based on the Armv8-M architecture and is suited for applications where security

is an important consideration.

The interfaces that the processor supports include:

Code AHB (C-AHB) interface

System AHB (S-AHB) interface

External PPB (EPPB) APB interface

Debug AHB (D-AHB) interface

The processor has optional:

Arm TrustZone technology, using the Armv8-M security extension supporting

Secure and Non-secure states

MPUs which you can configure to protect regions of memory

Floating-point arithmetic functionality with support for single-precision arithmetic

Support for ETM and MTB trace

Arm Custom Instructions

The processor is highly configurable and is intended for a wide range of high-performance,

deeply embedded applications that require fast interrupt response features.
