The CC3220x device within the CC3220MODx and CC3220MODAx modules includes on-chip SRAM to which application programs are downloaded and executed. The application developer must share the SRAM for code and data. The micro direct memory access (μDMA) controller can transfer data to and from SRAM and various peripherals. The CC3220x device ROM holds the rich set of peripheral drivers, which saves SRAM space. For more information on drivers, see the CC3220x API list.
