Security Keys

Safeguarding internet of things (IoT) applications from security threats involves device and server authentication, protection of sensitive data and intellectual property, and preservation of confidentiality and device and communications integrity. For example, consider an IoT node device. Such a device needs to have a secure bootloader and up-to-date secure firmware in order to safely send sensor data to a server over a TLS connection and to store sensitive data in flash memory. A key component in this equation is a security IC, used as a companion IC to application processors to ensure secure data exchange and to protect the data.

Protect medical devices with secure authenticators
The things around us—including medical devices—are getting smarter. There’s good and bad to this. On one hand, it’s hard to argue with the advantages of being able to be more proactive about healthcare. A patient with a smart, WiFi-enabled implanted pacemaker can, for example, send the wealth of useful data that the device continually collects directly to his or her doctor via a smartphone. Armed with this information, the doctor can more quickly (and remotely) evaluate the patient and potentially detect issues of concern. At the same time, however, connected pacemakers are vulnerable to hackers, who, with remote control over the devices, could create dangerous situations for the patients.

One Way to Replace Power Rail Clusters in Small Electronic Devices

December 10, 2018

Christine Young By: Christine Young

Smartwatches with SIMO power supplies


Today's consumer electronics landscape is dotted with tiny, battery-powered wearables, hearables, and other "ables." With a processor, speakers, microphones, multiple sensors, and radios, these devices struggle with opposing trends: there are more power rails at lower voltages and currents, yet conserving precious battery life is also essential for a good user experience. A wearable device, for example, might feature these rails: 3V at 20mA for RF, 1.8V at 20mA for digital functions, and 3.2V at 75mA for the motor drive. A smartphone could have rails ranging from 1.1V at 20mA to 1.8V at 300mA. Given the requisite tiny form factors of these battery-powered products, independent, point-of-load power rails are not feasible in these designs. Read More ›

Smart, secure devices

Do you have an internet of things (IoT) device at home? A smart TV, perhaps? Or a thermostat that senses when the heat needs to be turned on? More importantly, have you done your part to ensure its security? At a minimum, that means changing the device's default password. While users have a responsibility to protect their IoT applications from hacking, design engineers have an even greater obligation to defend their designs. That was the key takeaway from a keynote by a McAfee executive at this fall's Internet of Things Device Security Summit in Santa Clara, California. Read More ›

7 Key Steps to Empowering Innovation

November 13, 2018

Jeff DeAngelis By: Jeff DeAngelis
Managing Director, Industrial Communications, Maxim Integrated   

The excitement of launching an innovative new product is similar to the emotions felt when riding a rollercoaster.

Over the years I have found that delivering new technology into the market is a mixture of emotions similar to the excitement and anxiety as you ride a new roller coaster to the top of its first drop. The anticipation builds as you make your way to the peak, and then there’s the thrill of acceleration as you fly through the rest of the curves to the sudden de-acceleration as you come to a full stop at the end of the ride. Introducing a new product into the market for the first time pretty much feels the same way. You just never know if your product will have that "wow factor," that technical magic which elevates the industry to a new capability and helps define a new level of performance never before imagined. The process of innovation comes in many shapes and forms, yet there are some pivotal moments in the process that seem to define a method to stimulate innovation. While I wanted to share my insights on these seven pivotal steps that lead to innovation, this article is dedicated to my team who put in the effort and timeless dedication to bring our new products to market. These individuals often go unseen and they are rarely acknowledged. This peak behind the curtain, so to speak, provides insight on the magic of empowering innovation. Read More ›

Engineers Had Better Be Careful with AI

Muhammad ibn Musa al-KhwarizmiMuhammad ibn Musa al-Khwarizmi wrote of the 'calculus of resolution and Juxtaposition,' more briefly referred to as al-Jabr, or algebra.

Using algorithms and artificial intelligence (AI), anyone can produce a website which gathers news from other sites and then filters that information for any particular perspective. Or, if they have enough cash, they can buy an already famous website and then tune its content. Add a few vague references and a couple outright lies and you can have a powerful influencer—especially for people who prefer to read only brief bits of news and don't have the time to attempt to get the full story.

Designing a device that measures heart rate and blood-oxygen saturation level (SpO2) from the finger can be challenging. Through a principle called photoplethysmography (PPG), an optical biosensor measures heart rate by shining an LED light into the capillary in the wearer’s tissue at a depth that is sufficient to measure light that has traversed or scattered from the tissue. This movement of light reflects blood volume changes between systolic (when the heart expels blood) and diastolic (when the heart draws blood) heart beats. Read More ›

Robotic machinery

In industrial environments such as automated factories, high voltages are part of the landscape. Programmable logic controllers (PLCs), motor drives, certain power supplies, and even medical equipment and electric vehicles (EVs) all have circuits that must be protected from these voltages. Even more critically, people working in these environments must be guarded from electric shock. Digital isolation provides the means to do both, providing signal isolation and level-shifting to help ensure correct circuit operation and insulate users from electric shock. Read More ›
