Graphics LCD based on Microcontroller

The LCD reference design is developed using the Kinetis KL28Z through the standalone peripheral module FlexIO. The polling method is used to copy data from SRAM or flash to FlexIO's shifter buffer. Image Kinetis board is powered by an ARM® Cortex-M0, providing up to 96 MHz CPU performance besides supporting ultra-low power. KL28Z's FlexIO emulates…

The Quadro IoT Wi-Fi Kit

The addition of internet connectivity has become a key ingredient of a new generation of “smart products,” i.e., devices that combine sensing, processing, and communications capabilities with internet-based services and applications. The world’s leading businesses are rushing to offer these smart IoT products to gain an edge over the competition. Because of this, the total…

Low Power and Turns Count Sensing with the Angle Sensor IC

This article discusses the uses of the A1337 in battery-powered automotive and non-automotive applications with the need of the sensor to function in multiple mission modes. Automotive Systems Requiring Sensor Operation Even in Key-Off Conditions Certain automotive angle sensing applications require the ability to track angular position even in key-off conditions. In the key-off state,…

ARM Whitepaper

ARM Cortex®-M Processors are the most popular processor series in the electronics industry. With over 300 licenses, the Cortex-M processors are available in over 3500 microcontroller parts from most of the microcontroller vendors, and are also used in wide range of embedded applications including sensors, wireless communication ASICs, power management ICs and as companion processors…

Voltage Isolation in Variable Frequency Drives

Introduction In this application note, a VFD is used as an example system that must meet isolation standards through the use of insulation layers. Many of these same isolation concepts will apply to almost any system that has high voltage control components and a user interface. The basic assumption is that all equipment should be…

FFT Terminology in the Oscilloscope Environment

The ability to analyze the frequency domain with the Fast Fourier Transform (FFT) has opened up a whole new set of opportunities in digital oscilloscopes. However, the user needs to understand the capabilities and constraints of both the measurement techniques and the instruments that perform them. With the aid of practical examples, this paper helps…

Two-Phase Digital Power Factor Correction

Project Summary This High Power Two-Phase Digital Power Factor Correction reference design builds upon Digital Power Control technology and extends it to high power levels in the area of Power Factor Correction (PFC). It introduces fast switching, high current, high voltage X2-class MOSFETs and incorporates Digital Inrush Current Control concepts. Functional control is based upon…
