The major building blocks for a white-LED driver are an oscillator, a charge pump, and a regulated current source. National Semiconductor (www.national.com) produces a device that contains all these ...

The MAX7378 contains two oscillators and a power-on reset circuit for microprocessors. The Speed input selects either 32.768 kHz (LF) or a higher frequency, which is pre-programmed. The type number ...

How to set up an PIC microcontroller to deliver high-precision frequencies from 1 Hz to 4 MHz. Examples of the frequencies delivered by this microcontroller design. In timing applications, a time-base ...

It is one of our favorite chips, and the brains behind the Arduino UNO and its clones, and it’s getting a tweak (PDF). The ATmega328 and other megaX8-series chips have undergone a subtle design change ...

In this article, I'll be explaining the basics of how microcontrollers work, physically and virtually. First off, microcontrollers are no simple thing, so don't be discouraged if you find it ...

It’s generally pretty easy to spot a microcontroller on a PCB. There are clues aplenty: the more-or-less central location, the nearby crystal oscillator, the maze of supporting passives, and perhaps ...
