Just 1-Wire to Operate I2C/SPI Endpoints

March 3, 2022

Marco A. Ramirez Castro  By: Marco A. Ramirez Castro

Can I2C and SPI endpoint devices be powered and controlled with just a single wire?

It is possible to deliver power and data to operate I2C and SPI endpoints, such as humidity or temperature sensors, with the use of a single wire connection and ground using Analog Devices' 1-Wire® technology. This technology offers a robust solution when working with IO constrained systems where there may be just one or a few pins available on the host. The DS28E18 is a great example of a bridge device that leverages 1-Wire to address a common set of system challenges like wiring limitations, communication distance, and protocol conversion

relieving supply chain issues of the 1-wire silicon serial number chip

Two of the most popular long running legacy devices for more than 30 years, the 1-Wire® Silicon Serial Number DS2401 and DS1990A, has suffered supply chain issues. To relieve this issue, Analog Devices has developed the alternatives DS2401A and DS1990AA. These alternatives use a different wafer process that has greatly reduced lead times.

Keep the Lights On When Someone is Home

Have you ever wished for your power to go out? That's not a likely scenario, but kids doing chores like vacuuming that require power, have probably long wished for this exact situation. Ultimately, no one truly wants the power to go out because we need to work or keep working, relax and watch TV, or ensure the kids finish all their chores.

Smart Wake-up with Aizip and Maxim Integrated

False triggering of camera systems that need to wake-up when a person is present is more than a nuisance, it unnecessarily consumes energy, digital storage space and communications bandwidth. Plus, capturing photos or video of things you don't care about and sending cell phone alerts for no reason not only wastes resources, it also wastes your time. A smart wake-up solution from Maxim Integrated and Aizip can drastically reduce false positives to ensure the system stays off until really needed.

Factory Automation

Factories are getting smarter with the adoption of Industry 4.0 and with the advancement in robotics. Modern factories have multitude of sensors deployed throughout the factory for monitoring and collecting data. This data gets processed through Programmable Logic Controllers which are used for automation, asset management, maintenance, and repairs. Similarly, buildings are also getting smarter, not only to save energy, but also to increase the life of the facilities and to improve the comfort of the occupants. Modern buildings have several electronics deployed to manage assets such as elevators, water pumps, air conditioners and IT infrastructure.

MAX32660 Arm Cortex M4 Microcontroller with Embedded Algorithms

Since 2017, I've had the pleasure to work with one of Maxim Integrated's most unique microcontrollers, the MAX32660. With 256kB of Flash, 96kB of SRAM, a high-speed Arm-Cortex M4 with FPU, ultra-low power consumption at 50µA/MHZ in active power and optional bootloaders, this MCU packs a ton of capability into a ridiculously small form factor. Its most popular packages are a 3mm x 3mm TQFN and an incredible 1.6mm x 1.6mm WLP…crazy, I know. This makes it the world's smallest cortex-M4F powered microcontroller able to go into applications that are pushing the envelope and bringing complex algorithms into space constrained environments like never before.

More nanoPower technology tools for your toolkit

March 17, 2021

By: David Andeen
Director, Reference Designs, Maxim Integrated

Image representing the importance of having the right tools

Thinking about tools reminds me of when Maxim first announced a nanoPower device back in 2017, the MAX1722x family of nanoPower boost converters, which consume just nanoamps of quiescent current. These nanoPower devices are unique tools, optimized to consume as little power as possible and limit overall system power consumption. These tools power amazing new devices and applications that run longer from smaller power sources.

Can We Find Common Ground on Common Mode Range?

January 21, 2021

Common mode voltage—it can be a scourge for serial communication systems such as RS-485 or even CAN communications in noisy industrial systems. High common mode voltage can be due to an electrically noisy environment or nearby equipment, such as an AC motor, transformers, or power cables. Or, it could stem from the voltage differences in ground planes; for example, two nodes or systems that operate from different transformers or ground levels. These voltage differences occur because cabling can be hundreds of feet long, especially in RS-485. For example, a 1000ft long 24 AWG cable (25.67 Ohms per 1000ft) carrying 450mA of current can cause a difference in ground potential of 11.6V. It's easy to see that in a large factory or building, such voltage differences can be quite common. So whether the high common mode voltage is due to noise or ground level voltage differences, it can hamper reliable communications. In an application area like an automated factory, such errors can mean lost uptime and productivity.

Reference design showing SIMO PMIC powering multiple noise sensitive sensors, micro-controller, and display

The word "classic", in terms of games, resonates to everyone. To Bob Willson, it was spending his paper-route money to buy MicroVision's Blockbuster. To me, it is the fond memories associated with fighting with my elder sister over who gets to play the next round of Jardinanins! in our Windows 98 PC. What Bob and I have in common is that we were both hooked on games derived from Atari breakout, where the objective is to hit the bricks using a ball that bounces off a paddle. I incorporated these memories when designing my summer project as an intern at Maxim Integrated. My project is a demo that is "on the go" gaming platform featuring Maxim's low power SIMO PMIC, an m5 FG and sensors. It is a platform where you can track your vitals or play a classic brick breaker game.

The Dawn of the Self-Aware Machine

As Factories and Buildings strive to become smarter, they will benefit by achieving a boost in productivity, a reduction in operational expenses, achieving a smaller carbon footprint, and provide better real-time decision making. To achieve these benefits, it will require a new way of thinking by semiconductor companies to enable intelligent sensors & actuators, provide software configurable analog & digital IOs, and improved on chip diagnostics. Maxim Integrated's new portfolio of IO solutions, IO-Link® reference designs, Go-IO demonstration platforms, and intelligent actuators are bringing these benefits to the automation industry by empowering intelligence at the edge. This new intelligence, coupled with embedded AI capabilities like the recent announcement of the MAX78000 low-power neural network accelerated microcontroller, will form the foundation that will drive the next chapter in the Industrial Evolution 5.0+; "The Dawn of the Self-Aware Machine".

A secure system architecture uses a symmetric key secure authenticator and coprocessor

Cryptography offers robust protection against security threats, yet not every embedded designer is a cryptography expert. To provide product development engineers a quick path toward an understanding of the basics on the topic, we've created a Cryptography Handbook consisting of a series of tutorials that take an engineering rather than theoretical approach. In this blog post, I'll share highlights from each chapter and also show how secure authenticators and coprocessors can help simplify the process of integrating cryptography into your embedded design.

Snapshot GPS Receiver

One of the biggest challenges in adding GPS capability to battery powered devices such as vehicle trackers, asset trackers or IoT sensors is the shortened battery life. Increasing the size of the battery for longer runtime is, in almost all cases, not an option as this would increase, the size, the weight, and the cost of the wearable.
