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 ...

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 ...

Embedded-systems designers regularly need to store sensitive information, such as cryptographic keys, user data, proprietary algorithms, and other forms of intellectual property within firmware. To ...

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 ...
