14. Microcontrollers - Part A

Microcontrollers serve as integrated chips embedded in many common devices, performing specific tasks with simplified internal architectures. Their essential components include a CPU, memory (RAM and ROM), I/O ports, and peripheral devices, which distinguish them from microprocessor-based systems. This chapter explores the architecture, applications, and key features of various microcontroller types, especially focusing on the Intel 8051 family.
