Microchip adds 12 Products to its wireless portfolio that reduce barriers to Bluetooth integration

Fri, May 31, 2024

System designers face many barriers when adding Bluetooth functionality to their products, from skill and resource limitations to budget constraints to time-to-market pressures to challenging performance and integration requirements. Microchip has expanded its Bluetooth Low Energy portfolio with 12 new products, aimed at providing designers with an extensive array of choices to tackle their unique challenges, effectively lowering barriers across designs spanning from the simplest to the most advanced. These additions include the RF-ready WBZ350 module and the PIC32CX-BZ3 SoC that offers the lowest entry point available for integrating a Bluetooth Low Energy microcontroller (MCU) into product designs. For a list of all 12 products see Microchip’s Bluetooth Low Energy webpage.

In addition to its Bluetooth MCUs, Microchip introduced the RNBD350 plug-and-play module that reduces the cost and complexity barriers to adding Bluetooth Low Energy connectivity to product designs. These modules minimise the time, money and engineering resources required for RF design optimisation, regulatory certification and software development.

Sample applications for Microchip’s Bluetooth Low Energy parts include IoT smart home and building systems, Industrial IoT (IIoT) solutions and automotive designs.

Designers using the newly expanded Bluetooth Low Energy portfolio for entry-level applications benefit from an easy development process, including in-house support services and development tools, without compromising Bluetooth functionality.

Developers can also tap into Microchip’s expanding wireless portfolio for end-to-end solutions. The portfolio offers a range of products in popular wireless technologies like Wi-Fi, Zigbee, Thread and sub-GHz that are designed to work seamlessly with the Bluetooth portfolio.

IDS uEye XS weighs just 12 grams and fits into almost any application

Thu, May 30, 2024

The uEye XS from IDS weighs just 12 grams and fits into almost any application with its size of just 26.4 x 23 x 21.7 mm. Thanks to its autofocus and 5 MP CMOS sensor, it delivers consistently sharp images and videos from a distance of just 10 cm – for example in hand-held scanners, on robotic arms or in passport photo machines. The uEye XS starter set is ideal for testing the camera. In addition to the compact USB2 camera, it includes a cable, a tripod adapter and a tripod.

If the distance between the lens and the object is constantly changing, users benefit from industrial cameras with automatic focus. They eliminate the need for manual refocusing and ensure that objects or labels are always perfectly visible. When it comes to image quality, however, other factors are also decisive, such as natural colour reproduction and harmonious contrast.

IDS has therefore equipped the uEye XS with many other practical automatic features familiar from consumer technology. This includes white balance, exposure and gain. As a result, it delivers the best possible result in every situation. Anyone wishing to fine-tune even more precisely can adjust settings in the SDK (IDS Software Suite).
Thanks to its small size and the USB2 interface, the uEye XS camera is suitable as a component in embedded vision systems. It is used, for example, in medical or security applications, in transport and logistics or in kiosk systems.

New wireless-charging boards from ST for industrial, medical, and smart-home applications

Fri, May 24, 2024

ST has introduced a 50W, Qi-compatible transmitter and receiver combination to accelerate development of wireless charging for high-power applications such as medical and industrial equipment, home appliances, and computer peripherals.

Using ST’s new wireless-charging solution, innovators can leverage the convenience and speed of wireless charging in applications that demand a higher power and shorter charging interval. These applications include vacuum cleaners, cordless power tools, drones and other mobile robots, medical drug delivery devices, portable ultrasound systems, stage-lighting and mobile lighting, printers, and scanners. Free from cables, connectors, and complex docking arrangements, these products can become simpler, more affordable, and more robust.

The STEVAL-WBC2TX50 transmitter board is capable of delivering up to 50W of output power using the ST Super Charge (STSC) protocol. STSC is ST’s proprietary protocol for wireless charging at a faster rate than the standard protocols used with smartphones and similar devices, allowing quicker recharging of larger batteries. The board also supports the Qi 1.3 5W Baseline Power Profile (BPP) and 15W Extended Power Profile (EPP). The main component on-board is ST’s STWBC2-HP transmitter system-in-package, which combines an STM32G071 Arm Cortex-M0 microcontroller and an application-specific front end. The front end provides signal conditioning and frequency control, a high-resolution PWM generator to drive the transmitter, and operates with any DC voltage from 4.1V to 24V. It also contains MOSFET gate drivers and a D+/D- interface for USB Power Delivery. In addition, the STWBC2-HP SiP can work with ST’s STSAFE-A110 secure element to provide Qi authentication.

The STEVAL-WLC98RX receiver board is built to handle up to 50W charging power, to safely accommodate the full STSC capability as well as BPP and EPP charging. Features include support for Adaptive Rectifier Configuration (ARC), which extends charging distance by up to 50% to allow lower-cost coils and more flexible configurations. Accurate voltage and current measurement for Foreign Object Detection (FOD), thermal management, and system protection are also provided. This board uses ST’s STWLC98 wireless power receiver IC, which contains a Cortex-M3 core and an integrated high efficiency synchronous-rectifier power stage with programmable output voltage up to 20V.

Dedicated software tools, ST’s STSW-WPSTUDIO for the STEVAL-WLC98RX and STSW-WBC2STUDIO for the STEVAL-WBC2TX50 are available to modify the configuration parameters, tailoring the operation of the device to the needs of customised applications. A comprehensive set of design documents is also available to assist development.

Infineon launches new NFC tag for contactless authentication and secured configuration of IoT devices

Fri, May 24, 2024

The number of IoT devices is rapidly increasing, and they have already become a part of every industry. However, as the number of smart devices increases, so do the demands on the user experience in terms of simplicity of device configuration and pairing. To address this, Infineon has launched the OPTIGA Authenticate NBT, a high-performance NFC I2C bridge tag for single-tap authentication and secured configuration of IoT devices. It is the only asymmetric cryptography tag for sign and verify operations in the market certified as a Type 4 Tag by the NFC Forum. OPTIGA Authenticate NBT enables ultra-fast and seamless data exchange even with large data volumes. It enables contactless NFC (Near Field Communication) communication between IoT devices and contactless readers such as smartphones. It can be used for various applications, such as secured configuration of electronic devices without a display, activation of shared mobility vehicles, passive commissioning of unpowered smart light bulbs prior to installation, and data logging on patient health monitors.

OPTIGA Authenticate NBT offers superior security with Infineon’s Integrity Guard 32 security architecture, and the EAL6+ certification for both the hardware and the crypto libraries. The tag supports both symmetric and asymmetric cryptographic authentication as well as pass-through and asynchronous data transfer modes.

The device uses TEGRION hardware and enables a contactless interface speed of up to 848 Kbit/s and an I2C interface that supports up to 1 Mbits/s which results in the best performance values, particularly important for demanding applications. The NFC I2C bridge tag offers 8 KB of generous memory to store customer and application-specific configuration information. In addition, the high on-chip capacitance enables smaller antenna designs, optimising both BOM costs and space requirements.

Samples of OPTIGA Authenticate NBT are available now, and the devices will become available to the broader market in August 2024. The OPTIGA Authenticate NBT Development Shield and the OPTIGA Authenticate NBT development kit are also available to facilitate evaluation and design-in. In addition, developers can access technical documentation and extensive host-side integration support without having to sign a non-disclosure agreement (NDA).
