The architecture of an embedded system is centered around its microcontroller, also sometimes referred to as the microcontroller unit (MCU), typically a single integrated circuit containing the processor, RAM, flash memory, serial receivers and transmitters, and other core components. The market offers many different choices among architectures, vendors, price range, features, and integrated resources. These are typically designed to be inexpensive, low-resource, low-energy consuming, self-contained systems on a single integrated circuit, which is the reason why they are often referred to as System-on-Chip (SoC).
Due to the variety of processors, memories, and interfaces that can be integrated, there is no actual reference ...
