"WebbHeap Allocation The relatively low amount of on-chip SRAM available and lack of memory protection in an MCU means that heap use must be very carefully controlled to avoid memory leaks, overruns and attempted overallocation. Further, many RTOSes provide their own dynamic memory allocation system. " - Iar heap selection
