A microcontroller (MC, UC, or μC) or microcontroller unit (MCU) is a small computer on a single integrated circuit. A microcontroller contains one or more CPUs ( processor cores ) along with memory and programmable input/output peripherals.
A memory controller, also known as memory chip controller (MCC) or a memory controller unit (MCU), is a digital circuit that manages the flow of data going to and from a computer's main memory. [ 1 ] [ 2 ] When a memory controller is integrated into another chip, such as an integral part of a microprocessor , it is usually called an integrated ...

The first 32-bit ARM-based personal computer, the Acorn Archimedes, was originally intended to run an ambitious operating system called ARX. The machines shipped with RISC OS, which was also used on later ARM-based systems from Acorn and other vendors. Some early Acorn machines were also able to run a Unix port called RISC iX.
To communicate with the main computer system, several forms of communication can be used, including ACPI, SMBus, or shared memory. The embedded controller has its own RAM, independent of that used by the main computer system, and often its own flash ROM on which the controller's software is stored. Many BIOS updates also include upgrades for ...
A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers are commonly made as demonstration or development systems, for educational systems, or for use as embedded computer controllers .
The original AVR MCU was developed at a local ASIC house [clarification needed] in Trondheim, Norway, called Nordic VLSI at the time, now Nordic Semiconductor, where Bogen and Wollan were working as students. [citation needed] It was known as a μRISC (Micro RISC) [5] and was available as silicon IP/building block from Nordic VLSI. [6]
It is generally thought that PIC stands for "Programmable Intelligent Computer", General Instruments' prefix in 1977 for the PIC1640 and PIC1650 family of microcomputers, [4] replacing the 1976 original meaning "Programmable Interface Controller" for the PIC1640 that was designed specifically to work in combination with the CP1600 microcomputer ...
