Architecture Overview

Introduction

This architectural overview introduces the basic architecture of the C2000™ family of

microcontrollers from Texas Instruments. The F28x7x series adds a new level of high

performance processing ability. The C2000™ is ideal for applications combining digital signal

processing, microcontroller processing, efficient C code execution, and operating system tasks.

Unless otherwise noted, the terms C28x and F28x7x refer to TMS320F28x7x devices throughout

the remainder of these notes. For specific details and differences please refer to the device data

sheet, user’s guide, and technical reference manual.

Module Objectives

When this module is complete, you should have a basic understanding of the F28x7x architecture

and how all of its components work together to create a high-end, uniprocessor control system.

Module Objectives



Review the F28x7x block diagram and

device features



Describe the F28x7x bus structure

and memory map



Identify the various memory blocks on

the F28x7x



Identify the peripherals available on

the F28x7x
