Microcontrollers (sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit which is used to automatically control products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are also common, integrating analogue components needed to control non-digital electronic systems.
As the market for electronics rapidly expands, many of the required functions can be optimized by the use of small, powerful microcontrollers and at Softei we take the time to identify the best possible deals available throughout the UK for our clients.
A microcontroller is essentially a computer on a chip and they provide an economic means of electronically controlling a variety of products and devices, such as automobile engine control systems, remote controls, office machines, appliances, power tools, and toys.
Microcontrollers are used in a wide variety of applications, with newer generations offering greater power efficiency.
Some microcontrollers may use four-bit words and operate at clock rate frequencies as low as 4 kHz, for low power consumption (single-digit milliwatts or microwatts). They will generally have the ability to retain functionality while waiting for an event such as a button press or other interrupt; power consumption while sleeping (CPU clock and most peripherals off) may be just nanowatts, making many of them well suited for long lasting battery applications. Other microcontrollers may serve performance-critical roles, where they may need to act more like a digital signal processor (DSP), with higher clock speeds and power consumption.
