MICROCONTROLLERS A microcontroller (sometimes abbreviated µC, MCU) is a small computer with similar components as a standard personal computer only integrated on to a single chip and usually dedicated to a single task. The fundamental components include a processor core (C.P.U), memory, system clock and programmable input/output peripherals. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications...

Microcontroller: Output and Pin

Microcontroller A microcontroller (mcu or µc) is a small computer on a single integrated circuit consisting of a relatively simple CPU combined with support functions such as a crystal oscillator, timer, watchdog, I\O etc. Microcontrollers are designated for small applications. Thus, in contrast to the microprocessors used in personal computers and other high performance applications, simplicity is emphasized. Microcontrollers operate at frequency as low as 12 MHz, as this is adequate for many...

Applications of Microprocessor and Microcontroller

to a microprocessor include address, control and data busses that allow it to select one of its peripherals and send to or retrieve data from it. Because a microcontrollers processor and peripherals are built on the same silicon, the devices are self-contained and rarely have any bus structures extending outside their packages. Microcontrollers integrate a microprocessor with peripheral devices for control of embedded system. A digital signal processor (DSP) is specialized for signal processing. Graphics...

A Digital Voltmeter Using 8051 Microcontroller

input amplifiers, and, like vacuum tube voltmeters, generally have a constant input resistance of 10 mega-ohms regardless of set measurement range. This project aims at building a Digital Voltmeter using an 8051 microcontroller. All the data accessed and processed by the microcontroller is the digital data. And thus, the usage of an analog-to-digital converter finds its necessity here. A standard analog-to-digital converter ADC0804 is used in the current project. The input voltage (which is the analog...

A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications. Microcontrollers are used in...
