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 ...

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

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

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 ...

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 ...

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 ...

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 ...

We used to need SBCs for these projects; modern microcontrollers handle them more easily and inexpensively while being easier to maintain.
