Free technical guide: getting the best from Reed Relays

If used correctly, a reed relay is a superbly reliable device. The switch contacts are hermetically sealed and do not suffer from oxidization in the same way as an open electro-mechanical relay. Although in reality, relays are often considered slightly mundane and little thought is given to them which sometimes leaves them vulnerable.

Software Architecture for Arm Cortex-M Microcontrollers: Doing it right first time to improve developer productivity

In this paper we will look at how we can develop a standard software architecture for small microcontrollers that makes best use of both the software standards developed by Arm and their partners and a small footprint Real Time Operating System (RTOS). The key aim of such an architecture will be to improve developer productivity via reuse, testing, early software development, improved workflow and improved design methodology.

Implementing Bluetooth LE data pumps

?This document describes a specific group of Bluetooth Low Energy(LE) use cases, referred to as data pump applications, in which an external microcontroller pushes and pulls data through a BLE-capable device.

How to Select the Correct Spring-Loaded Connector for Today's Interconnect Applications

Connectivity is more crucial than ever in modern electronics designs. The widespread availability of proven-reliable connector technologies that facilitate both miniaturization and problem-free, long-lasting connectivity has made a significant contribution to the growth of modern devices and other applications. Spring-loaded connectors are one such technology and have grown in popularly due to benefits including: tolerance forgiveness, compatibility with uneven mating surfaces and blind mating applications, and ease of use.

IoT security guide whitepaper

Everyone knows that security is critical for IoT (Internet of Things) devices but how much is needed for various types of devices? Obviously control systems in a nuclear reactor need a higher level of security than that in a home toaster. But how does an engineer decide?

Triac and quadrac design innovations can simplify LED lighting control

Triacs are at the heart of dimming controls for LED lighting. Triacs used in dimmers have normally been characterised and specified for incandescent lamp loads, which have high current ratings for both steady-state conditions and initial high in-rush currents, as well as very high end-of-life surge current when a filament ruptures.

Magnetic sensing in washing machines

Like many modern appliances, washing machines today use a variety of sensors to ensure proper, safe, and energy-efficient operation. Littelfuse's magnetic sensor products help make these appliances as reliable and efficient as ever.

How magnetic sensors are helping to drive changes in appliance designs

From measuring electricity usage to turning off lights via remote control, smart technology is part of many of today's consumer electronic devices. Within the home appliance industry, sensors are playing a significant role in how consumers interact with smart appliances like washing machines, dishwashers and refrigerators. Temperature sensing and control are among the most important and well-established sensor functions in modern home appliances.

Analysis to reduce time to find bugs by up to 50%

If you're spending more than 50% of your verification effort in debug, you're not alone. For many design, verification, and embedded software engineers as well as engineers verifying complex standard protocols, debug is the primary bottleneck in verification.

Automotive Circuit Protection

The designers of automotive electronics face many technical challenges during the system design process, including designing methods of protection against a variety of electrical hazards.

Safety standards in the ARM ecosystem

Safety is an increasingly important topic for system developers and there is an ever widening range of relevant safety standards that system developers need to be aware of. The increasing use of electronics in cars, medical equipment and the Internet of Things (IoT) has led to new safety standards and new demands on developers of hardware and software.

Virtualisation and the Internet of Things

Industrial control devices have been around for years. The initial devices were manufactured with a personality, a business logic that was already built in when they left the manufacturing plant to perform one fixed function (and nothing else). They were deployed for specific tasks such as controlling industrial equipment, electricity generation, power plants, trains, planes, or automobiles.

New life for embedded systems and the Internet of Things

The Internet of Things (IoT) is no longer a fanciful vision. It is very much with us, in everything from factory automation to on-demand entertainment. Yet by most accounts, the full potential of interconnected systems and intelligent devices for changing the way we work and live has barely been tapped.

Advantages of capless LDOs

Power management of battery powered electronic devices is becoming increasingly more important for the present and future microelectronics industry.

What is EMC testing?

Testing of products under EU guidelines to ensure they don't either pollute the air waves or are susceptible to them is known as EMC testing. If a toaster either emits a lot of electromagnetic noise and upsets other electronic devices, e.g. your mobile phone, or it is unduly susceptible to noise emitted from another device, e.g. a call on your mobile phone causes the toast to 'pop up' when the bread is still white, the toaster is likely to fail EMC testing.
