Presented here is one ‘universal’ power supply unit for today’s microcontroller projects. The circuit is a compact power supply capable of providing +5 and +3.3V regulated outputs as VCCs (VCC1 and ...

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 ...

The audio component centers around the SS8550 PNP transistor (Q1) which serves as a driver for the passive buzzer (BZ1). This ...

Is it possible for a tiny microcontroller to run on a massive 48-V battery? This DIY electronics project makes it happen with ...

Like any measurement system, though, 4–20-mA loops need calibrating. There are many loop calibrators on the market (Figure 2 ), but they can cost up to $2000. As an alternative, we’ve designed and ...

Most of you know how an NFC tag works. The reader creates an RF field that has enough energy to power the electronics in the tag; when the tag wakes up, two-way communication ensues. We’re ...

Process migration and improved circuit design have resulted in major power savings over the years. However, this exposed leakage current as a major source of energy loss, particularly in systems that ...

By Zhao Qian, Bhaskarabhotla Leela Madhuri, Microcontroller Department Infineon Technologies Asia Pacific Pte Ltd, Singapore Abstract This paper discusses about a low cost, portable, reusable platform ...

A-PMD realizes low power consumption and advanced functions, while incorporating highly versatile peripheral circuits, such as UART, I 2 C, TSPI and timers, and supports high-end home appliances ...

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.

Shifting gears The operating frequency of a device has a direct (most of the time linear) impact on the power consumption. The slower the clock, the lower the power consumption. When selecting a ...
