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
