2 Mb density F-RAM rad-hardened for extreme environments
Infineon Technologies LLC announced the availability of the space industry’s first radiation-hardened (rad-hard), serial interface Ferroelectric RAM (F-RAM) for extreme environments. The new devices deliver unsurpassed reliability and data retention and are more energy-efficient than non-volatile EEPROM and serial NOR Flash devices for space applications. The addition of a QML-V qualified F-RAM to Infineon’s memory […]
Practicalities of specifying 5G antennas for the IoT
Antennas can be an afterthought in many designs. With the deployment of 5G, the need to get the most out of the antenna will only become more important. Josh Mickolio, Digi-Key Electronics There are a lot of assumptions, confusion and questions about how 5G will impact the non-handset world. There are several high-level goals for […]
The evolution of woven fiber optic circuit boards and connectors
During the ’60s and ’70s, the early mainframe computers and Telcom switches used complex dense wire-wrap technology. High-circuit-count copper backplanes and midplanes often relied on wire-wrap point-to-point, or pin-to-pin layouts. This involved lots of hook-up wire and singular micro-coax for the clock circuits. The wire-wrap pin backplane connectors at that time typically had round-wired edge […]
Edge computing security: Challenges and techniques
By Rob Oshana, Vice President Software Engineering, Research and Development, Edge Processing at NXP Semiconductors In today’s connected world, a growing number of applications depend on embedded devices, collecting and acting upon data from a wide range of physical processes. As the computing power of the Systems-on-Chip (SoC) at the heart of these devices continues […]
Connector standard helps pave the way to the IIoT
A new universal connectivity standard will help bring Single-Pair Ethernet to the Industrial Internet of Things. Eric Leijtens, TE Connectivity The rise of the Industrial Internet of Things (IIoT) places new demands on industrial networks. With the increasing number of IIoT nodes, there’s a need for a simplified, economical communication infrastructure at the field level. […]
How to turn off a smart meter the hard way
Potential cyber attacks have a lot of people worried thanks to the recent conflict in Ukraine. So it might be appropriate to review what happened when cybersecurity firm FireEye’s Mandiant team demonstrated how to infiltrate the network of a North American utility. During this exercise, Mandiant hacked into the utility’s industrial control systems and switched […]
On the drawing boards: Next-gen IoT power control electronics may sit on a PCB smaller than a U.S. quarter
Here’s the rub when it comes to modernizing the outlets, switches and circuit breakers that characterize ac electrical systems: Any innovations must interoperate with an installed base of equipment that may have been in place for decades. Manufacturers say issues surrounding compatibility with installed equipment have slowed the rate of introduction for technologies such as […]
