Authentication IC ties up with IoT SaaS for in-field provisioning
An off-the-shelf secure authentication IC combined with cloud-based security software-as-a-service (SaaS) claims to manage and update embedded security credentials in the field instead of being limited to a static certificate chain implemented…
LoRa module aims to simplify wireless design
The integrated Type 2GT multiband LoRa radio module from Murata reduces IoT device complexity and streamlines the certification process. It provides LoRa and Long Range-Frequency Hopping Spread Spectrum (LR-FHSS) communication over sub-GHz and…
Smart gate driver controls automotive motors
Toshiba’s SmartMCD series of gate drivers with embedded MCUs offers sensorless control of three-phase BLDC motors in automotive applications. The first entry in the series, the TB9M003FG combines a 32-bit Arm Cortex-M0 core, 64 kbytes of flash…
Reference designs offer LoRa gateway solutions
LoRa Corecell full-duplex gateway reference designs from Semtech are tailored to address applications operating in the U.S. 915-MHz and China 490-MHz ISM bands. Both the SX1302CFD915W1-H (915-MHz) and SX1302CFD490GW1 (490-MHz) reference designs…
Instrument improves oscilloscope calibration
A multichannel oscilloscope calibration system, the Fluke 9500C automates time-consuming testing to maintain scope accuracy and reliability. The 9500C provides simultaneous output on all channels and can be fully automated with MET/CAL software…
Security IC teams with key-management SaaS
Microchip has added its ECC608 TrustMANAGER with Kudelski IoT’s keySTREAM software as a service (SaaS) to its Trust Platform of devices, services, and tools. The cloud-based key-management SaaS integrates with the ECC608 secure authentication…
The ML-enabled edge MCUs available in three design tiers
A new family of microcontrollers optimized for machine learning (ML) applications at the edge claims to enable real-time command and response, eliminating the need for cloud connections while substituting high-performance microprocessors.
Infineon…
Solar-mains hybrid lamp
Introduction
Solar day lamps (SDL) are simple and cost-effective. A few examples of SDLs have been described in [1], [2] and [3]. An SDL without any energy storage element suffers from frequent changes in the light intensity. Also, a backup…
No floating nodes, Part 2
Some of the commentary in response to Part 1 on this topic suggested that the two 1 pF capacitors, C4 and C5, had to be put in series for lack of availability of 0.5 pF parts.
A simulation of that presented circuit is seen as follows:
Figure…
A groovy apparatus for calibrating miniature high sensitivity anemometers
Anemometers are an important category of environmental sensor. Articles about their design, data capture, and linearization have comprised topics featured in EDN Design Ideas, several quite recently.
Less well covered, however, has been the…
The LED-based BR40: A bulb begging for placement that’s drafty
When I did my first teardown of a LED-based light bulb nearly eight years ago, I figured it’d be a one-and-done. In coming to that premature conclusion, however, I didn’t consider the added functionality (such as network connectivity) enabled…
Are ghiplets the next evolution stage in GPU designs?
When GPUs are implemented in a chiplet arrangement, can they be called ghiplets? Semiconductor industry professional Chetan Arvind Patil thinks so. In his blog “The Rise of Semiconductor Ghiplet,” Patil outlines the benefits of GPUs in chiplet…
