Lattice Semiconductor Corporation (NASDAQ: LSCC), the low power programmable leader, today announced major performance and design flow enhancements for its award- winning Lattice sensAI™ solutions stack. The Lattice sensAI stack provides a comprehensive hardware and software solution for implementing low power (1mW-1W), always-on artificial intelligence (AI) functionality in smart devices operating at the Edge.
IHS forecasts 40 billion devices will be operating at the network Edge by 2025. For reasons including latency, network bandwidth limitations, and data privacy, OEMs designing always-on Edge devices want to minimise sending data to the Cloud for analytics. Lattice sensAI enables such OEMs to seamlessly update their existing designs with low power AI inferencing optimised for their application requirements. Incorporating such local intelligence also lowers expenses related to Cloud-based analytics by only sending relevant data for further processing.
m New 30º beam angle SMD LEDs from OMC emit
light further for high-intensity applications Enables light transmission over greater distances; applications include signalling, indication, sensing and data-communication
OMC, the pioneer in optoelectronics design & manufacture, has introduced a new range of narrow angle, surface-mount LEDs in a variety of package styles and all popular LED wavelengths. The new SMD emitter series features integrated lenses moulded into the package which provides a 30 degree output beam. Applications for visible wavelengths include signalling and indication, in which the beam needs to be visible over greater distances, while the company’s infrared wavelength versions are used for sensing and data-communication over greater distances and with higher precision than using standard, wide-angle SMD components.
Traditional through-hole (non-surface-mount) LEDs are commonly produced with narrow output angles as the LED body is generally moulded around the leadframe using an optical epoxy or silicone. The LED body itself then acts as the lens, focusing the light into beam angles as narrow as 5 degrees, with 30 degrees being a common requirement for many indication and sensing applications. However, with the move to surface- mount components, some design versatility was lost as the LED body is generally injection moulded from non-optical material which is pre-manufactured before the LED die is mounted, and does not therefore form a lens in the same way. As a result, the majority of SMD packages do not incorporate any lensing, emitting light in a wide beam angle which generally exceeds 100°.
Using a proprietary post die-mount encapsulation process, OMC is able to cost-effectively integrate narrow angle lensing into a range of surface-mount emitters, and can now offer 30 degree beam angles for all standard LED wavelengths, including infrared.
The SCALE-iFlex gate-driver system enables easy paralleling of the industry’s latest dual power modules, providing reliable and highly flexible system scalability with minimum development effort. The MAG is placed adjacent to the modules’ control terminals to provide excellent switching performance, and the IMC performs all necessary communication between the MAGs and the user’s MCU handling functions such as PWM commands, short-circuit and under-voltage failure reporting, as well as NTC and DC-Link voltage measurement.
The IMC is available with either an electrical or a fiber-optic interface with reinforced isolation, in accordance with EN 50124-1, IEC 61800-5-1 and UL 61800-5-1 for 1700 V and 3300 V power modules. The fiber-optic IMC also meets basic isolation requirements for 4500 V semiconductors. Devices feature double-sided conformal coating; units undergo full In-Circuit Tests (ICT) and are 100% Hipot and partial-discharge tested to ensure unmatched reliability. The devices include a full set of protection features such as under-voltage lock- out, short-circuit protection with Advanced Soft Shut Down (ASSD) and NTC temperature sensing with reinforced isolation (up to 3300 V).

I/O connector series launched by Nicomatic Optimus is available custom-configured; waterproof and with EMI protection
Nicomatic, the leading manufacturer of high- performance interconnect solutions, is launching Optimus, an EN4165-compliant, modular, rectangular I/O connector series. This low-profile interconnect solution is user-configurable and is applicable either to provide an equipment interface connection to a harness or as a robust rack & panel solution.
Conforming to specifications set out in EN4165, Optimus connectors are highly versatile. Modular construction enables designers to specify the layout they need. Connectors can be configured with size 22 signal contacts rated at 5A or size 8 power contacts rated for 60A. 90° PCB mount versions are also available. Devices are waterproof and offer EMI protection.
Comments Alexis de Lassat, product manager at Nicomatic: “We have applied Nicomatic’s modular manufacturing philosophy to the industry-standard EN4165 hi-rel rectangular I/O connector, and we are able to design and deliver mechanical solutions adapted to the specific requirements of our customers on optimised lead times. With this new connector series we can now offer connectors for the whole equipment need – from the miniaturised inside the box connector to the robust Optimus I/O equipment interface.”
The new Optimus EN6145 connectors can withstand 500 mating and de-mating cycles as per EN2591- 406. Devices also meet the shock and vibration requirements of EN2591-402/403 and have an operating temperature range of -55 to +175°C. The connectors provide excellent protection against EMI and withstand 10 times lightning strikes of 10KA, 1600V.”
m Pickering Electronics announces miniature, cost-effective
relays used extensively in PXI switching matrixes Series 117 reed relays offer high performance and reliability at a competitive price point
Pickering Electronics, the reed relay company which has pioneered miniaturisation and high performance for over 50 years, has announced that its two-pole single-in-line (SIL) 117 series reed relay is being extensively used in large switching matrixes due to a combination of small size, performance and cost.
All models in the 117 series are rated at 100V and can a carry up to 0.5A signal current and switch 5W of signal power. Versions are available that support 3V coil drives for systems working at low supply voltages. The two pole version has a footprint of just 10.16mm x 3.81mm, while the single pole device occupies just 6.86mm x 3.81mm - just 38% and 26% respectively of the board area required for industry-standard SIL relays.
The 117 series reed relays are constructed using Pickering Electronics SoftCenter®
integral magnetic screen, ensuring that the relays exhibit excellent reliability and avoid magnetic interaction issues when closely packed together. Devices are also priced very competitively, and it is this combination of attributes – size, performance and price - that suit them so well for use in high volumes in PXI and other switching matrix solutions.
Pickering Interfaces is a provider of such test and measurement solutions and uses 117 series reed relays extensively in many of its products, including the BRIC™ high-density, fully scalable, integrated PXI large matrix modules with built-in high-performance analogue bus. Available in 2, 4, or 8 slot 3U versions, rated at up to 150V, 1A and 20W, these units rely on Series 117 high-reliability instrument- grade reed relays to deliver the performance required by demanding applications in defense, automotive and semiconductor manufacturing industries.
