Specification 5.2.2 · Paper 1
Revise: Control Devices and ComponentsA microprocessor is an integrated circuit containing a central processing unit, or CPU. It executes instructions from a program, carrying out calculations, comparisons and control operations. In a complete system, it normally works with external memory that stores instructions and data, and input/output circuitry that connects it to other devices.
Component 1
A microcontroller integrates a processor, memory and input/output functions on one chip. A microprocessor normally needs external memory and input/output circuitry to form a complete system.
