Introduction
The purpose of this application note is to give a presentation of the CCM RAM available on
STM32F303xB/xC and STM32F313xC microcontrollers and describe what is required to
execute part of the application code from this memory region using different toolchains.
This application note is divided into four sections: the first section gives an overview of the
STM32F3 CCM RAM, while the next sections describe the steps required to execute part of
the application code from CCM RAM using the following toolchains:
• IAR EWARM
• KEIL MDK-ARM™
• RIDE and Atollic GNU based toolchain
The procedures described throughout the document are applicable to other RAM regions
such as the CCM data RAM of some F4 devices, or external SRAM.
