The 0- to 20-mA current loop isa reliable means of data communicationin industrial applications.These circuits use a precision shunt inthe receiver to convert the current signalinto a voltage signal.

The MCP120 is a microcontroller voltage supervisory circuit with open drain output. This voltage supervisory device is designed to hold a microcontroller in reset until the supply voltage has reached ...

Chris Gammell wants to know: What’s in your circuit toolbox? Personally, mine is somewhat understocked. I do know that in one of my journals, probably from back in the 1980s, I scribbled down a ...

Deep in the heart of your latest project lies a little silicon brain. Much like the brain inside your own bone-plated noggin, your microcontroller needs protection from the outside world from time to ...

Freescale Semiconductor added three new families to its Kinetis E microcontroller (MCU) series, which are built around the ARM Cortex-M0+ architecture. The KE02 (running up to 40 MHz), KE04 (up to 48 ...
