Web9 mrt. 2024 · Arduino® Boards Memory Allocation. As stated before, Arduino® boards are mainly based on two families of microcontrollers, AVR® and ARM®; it is important to know that memory allocation differs in both architectures. In Harvard-based AVR architecture, memory is organized as shown in the image below: AVR memory map. WebAVR microcontrollers are using Harvard architecture. This means that separate memory types (program memory and data memory) are used and connected with distinct buses in this architecture. Such memory architecture allows processors to access program memory and data memory at the same time.
