Many small microcontrollers require so little power that often they can draw what they need through their loads. This can simplify a system, reduce its cost, increase its reliability, and provide ...

Editor’s note: I (Steve Taranovich) was a pure analog engineer with Burr-Brown Corp. until the year 2000 when Texas Instruments integrated Burr-Brown into its organization. At that point, I knew that ...

Arithmetic logic unit (ALU), which performs computation. Registers needed for the basic operation of the CPU, such as the program counter (PC), stack pointer (SP), and status register (SR). Further ...

This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors (see the figure). The circuit can find applications in light-tracking systems ...

Slimmed-down version of Python, rebuilt from the ground up, is designed to run fast and lean on microcontroller hardware The Python programming language’s flexibility and ease-of-use have made 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 ...

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...
