Texas Instruments

Published Date: 26 Jul 2018


This application report documents ways to increase the available random access memory (RAM) for your application on the CC2640R2F SimpleLink™ Bluetooth low energy microcontroller. By moving initialized data or compiled code from the SRAM into other parts of the memory, the available SRAM is increased. This application report also highlights some of the tools found in the SimpleLink CC2640R2 software development kit (SDK) that enables optimization of the RAM used by heap and stack memory. Note that the features described in this document are not profiled in terms of power consumption or processor speed.
