This year, 2022, has been a year chocked full of new technology, from RISC-V chips to new oscilloscopes. As the new year approaches, it’s always important to see where you’ve been before looking to where you’re heading.
In this article, let’s take a look back at some of our (and maybe some of your) favorite new tech and news to come out of 2022.
When 5G Threatened Thousands of Flights
As bright, shiny, new tech starts to make its way as a common technology, often there are hiccups (usually unexpected) along the way.
One instance happened early on in January 2022, with AT&T and Verizon delaying a mass 5G rollout near airports because the 5G C-band could mess with plane altimeters.

RISC-V Took a Shot at Easing the Continuous Chip Shortage
As you’re well aware, the chip shortage has been an ongoing issue in everyone’s newsfeeds since 2020. Tons of solutions have been proposed, from funding for semiconductor fabs to companies switching to in-house chips, each hoping to ease the burden the industry has been struggling with.
One potential solution that has its merits is the use of RISC-V. RISC-V is an open-source chip architecture that has grown in use and popularity over the years. Hoping to leverage its benefits, namely how easy it makes custom chip designs, many companies have started exploring and creating chips using this open-source technology.

Tektronix Shrunk Bench Quality Oscilloscopes Down to Size
The shrinking of technology is nothing new. We’ve gone from brick-sized mobile phones in the 80s to tiny supercomputers (which also function as phones) that can easily fit into a pocket. As chips get more efficient and smaller, so does the technology those chips go into (plus the ones that help with the design and testing processes of said chips).

Bench oscilloscopes tend to have more bells and whistles than their handheld or portable counterparts. However, they can be a bit bulkier. After a 3-year effort, Tektronix released a thin version that can fit into a basic laptop case. To learn more about this innovation, check out the original article on the 2 Series MSO:

For 6 Dollars, Wi-Fi Came to IoT Designs With Raspberry Pi Pico W
Introduced back in January 2021, Raspberry Pi released its first MCU-based product. After a year and a half on the market, this breakout board, the RP2040, had a major upheaval by adding wireless connectivity.

This board added two new ways of wireless communication: 1) using a wireless system-on-a-chip (SoC), like the CC3100 Wi-Fi network processor from TI, and 2) using a wireless module. Not only did this board add new features for makers, but it also came in at a great price point of just $6 USD.
Check out the original article to learn more about this board when it was released back in July:
At Just $6, Raspberry Pi Pico W Brings Wi-Fi to IoT Designs
Getting an Education in PCB Design Got Easier Thanks to Altium
The need for PCB designers is always lucrative and in high demand. One solution for bolstering new PCB design recruits is called “Altium Education.” This program provides a variety of open-source or free online educational modules to teach students and those new to PCB design.

Altium Education lays out PCB education both through text- and video-based units. Overall, this program hopes to spark interest and create a foundation for future PCB designers. If you want to learn a bit more about this program, take a look at the article here:

Texas Instruments Zeroed in on Safer EVs With Solid-state Relays
As electric vehicles (EVs) start to become more commonplace, it’s important for them to, of course, be safe. Aiming to do just that, Texas Instruments created two solid-state relay chips designed to replace traditional automotive mechanical relays.

Hoping to get the inside scoop on these new solid-state relays, All About Circuits’ editor-in-chief, Jeff Child, had the opportunity to interview Priya Thanigai, the Manager of Power Switches at TI. Check out Jeff’s article on these new relays, how they aim to create safer EVs, and the technology being incorporated, namely the on-chip isolation barrier:

IoT Virtual Hardware Got a Boost From Arm’s M85 Core
The Internet-of-Things (IoT) was once a new technology but has since skyrocketed into being a key technology for many companies to create technology for, from chips to Wi-Fi protocols. Jumping into the foray to keep this technology advancing comes Arm’s latest core processor, the M85.

AMD Pushes Past Custom Robotic Designs With SOM Kit
In the past, we’ve covered Kria SOMs (system-on-module). AMD, leveraging Xilinx’s technology (which was acquired this year), created a Kria KR260 Robotics Starter Kit. Announced during this year’s 2022 Embedded Vision Summit, this new kit hopes to accelerate industrial robotic designs. To do so, it uses adaptive system-on-chip (SoC) technology, a robot operating system 2 (ROS 2), and an approach to pre-built robotics interfaces similar to an “app store.”

Siemens Tried to Break Down Barriers for DFM Design With PCBflow
EDA tools are constantly evolving and fighting to become a staple in a design engineer’s workflow. One tool that stood out this year was Siemens’ PCBflow. Announced at 2022’s Electronica trade fair, this tool seeks to provide PCB design-for-manufacturing (DFM) for small organizations and individual engineers.

Thanks to an interview with Susan Kayesar, PCBflow Technical Product Manager at Siemens, we learned more details about this new tool and all of its bells and whistles, namely how it helps clear up the lag in communication between the PCB designer and the PCB manufacturer. To see what other ways EEs could benefit from PCBflow, take a look at the article down below:

Not Technically ‘New’ News—Hedy Lamarr, the Mother of Wi-Fi
Though not technically “news,” we sometimes like to create articles looking back on history and recognizing those that made waves in the world of technology. One of our favorite historical engineer articles of 2022 was on how actress, Hedy Lamarr, was considered the “mother of Wi-Fi” and helped create the foundation for modern radio frequency (RF) technology.
