Microcontroller Circuits


That Section include a load of circuits and projects that use microcontrollers. Microcontrollers are hidden inside a surprising number of products these days.All modern automobiles contain at least one microcontroller, and can have as many as six or seven. The engine is controlled by a microcontroller, as are the anti-lock brakes, the cruise control and so on. If your device has an LED or LCD screen and a keypad, it contains a microcontroller. Any device that has a remote control almost certainly contains a microcontroller: TVs, VCRs and high-end stereo systems, etc.Basically, any product or device that interacts with its user has a microcontroller buried inside. Start working with microcontrollers yourself -- create a microcontroller programmer, or what about a digital clock with a microcontroller! or a digital thermometer!

A microcontroller (sometimes abbreviated µC, uC or MCU) contain 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. A microcontroller is a small computer on a single integrated circuit consisting of a CPU combined with peripheral support functions such as a crystal oscillator, timers, watchdog timer, serial and analog I/O etc. Program memory is also often included on chip, as well as limited RAM. Designed for small or dedicated applications, microcontrollers differ from the microprocessors used in personal computers and other general purpose applications, in that simplicity is emphasized. Microcontrollers are "embedded" inside some other device (often a consumer product) so that they can control the features or actions of the product. Another name for a microcontroller, therefore, is "embedded controller." Microcontrollers are dedicated to one task and run one specific program. The program is stored in ROM (read-only memory) and generally does not change.

Microcontrollers are often low-power devices. A desktop computer is almost always plugged into a wall socket and might consume 50 watts of electricity. A battery-operated microcontroller might consume 50 milliwatts. Maxim's microcontrollers provide low-power, efficient, and secure solutions for challenging embedded applications. Our 16-/32-bit processors embed cutting-edge technologies to secure data and intellectual property, proven analog circuitry for real-world applications, and battery-conserving low power operation.
