WebA microcomputer made on a single semiconductor chip is called single-chip microcomputer. Since, single chip microcomputers are generally used in control applications, they are also called microcontrollers. Microcontroller contains all essential components of a microcomputer such as CPU, RAM, ROM/EPROM, I/O lines etc. WebCC, GND, XTAL1, XTAL2, , , ALE and RST are the other 8 pins available on microcontroller chip. V CC (Pin 40) Voltage input is +5V, purpose of V CC is to supply voltage to microcontroller. GND(Pin 20) Ground is also provided in 8051. XTAL1 AND XTAL 2(Pins 18 and 19) An external clock is required to run 8051.
