Monolithic radio supports Wi-Fi 6, Bluetooth 5.2 and 802.15.4

Believed to be the first secure tri-radio device, NXP has introduced the IW612 at CES 2022, in Las Vegas. It enables simultaneous transmit and supports Matter, the interoperable, secure connectivity standard for smart homes. 

It supports the Wi-Fi 6, Bluetooth 5.2 and 802.15.4 protocols for seamless, secure connectivity for smart home, automotive and industrial use cases, says the company. 

Consumers are therefore not restricted to single protocol ecosystems but can access different ecosystems and wireless network technologies. The three protocols can work together: Wi-Fi 6 reduces network congestion, extends range, improves robustness and lowers power; Bluetooth 5.2 is suitable for audio (A2DP, LE Audio), voice and network commissioning; and 802.15.4 is suitable for Matter with Thread mesh networking.

One of the primary challenges facing the IoT is limited interoperability, which can restrict the consumer’s ability to mix smart home products from different companies. Matter is a new standardised IoT connectivity protocol, designed by a consortium which includes NXP, which unifies how devices communicate, independent of the manufacturer or wireless technology. The protocol creates more connections between more objects, to simplify development for manufacturers and compatibility for consumers.

The IW612 overcomes hardware co-existence challenges that developers face today, while also enabling advanced security protocols to tackle security threats faced by the IoT, explains NXP.

It offers secure boot, debug and over-the-air firmware updates for ongoing protection, as well as WPA3 security and hardware encryption engines. 

“With the IW612, developers can leverage different wireless connectivity protocols on a single device to create an easy-to-use, secure product for smart home, industrial and automotive use cases,” said Larry Olivas, vice president and general manager for Wireless Connectivity Solutions, NXP Semiconductors. The tri-radio technology can operate across door locks and smart speakers to in-vehicle entertainment and telematics, he added.

“Interoperability has been a key challenge that has fragmented the smart home market for years, but Matter-enabled devices can change that,” confirms Jonathan Collins, research director at ABI Research.  

The IW612 can be used for border routers, bridges and gateways in the smart home that require connecting Thread or Bluetooth devices to the cloud using the integrated Wi-Fi 6 radio. Additionally, the IW612 enables communication between Matter devices regardless of whether the devices use Wi-Fi or Thread. This allows Matter-over-Wi-Fi products to control and monitor Matter-over-Thread devices, and vice versa. 

The IW612 is sampling now.

SoC can support the Bluetooth LE spectrum, says Infineon

The Airoc CYW20829 Bluetooth LE (low energy) SoC is a Bluetooth 5.3 core spec-compliant device for IoT, smart home and industrial applications, introduced by Infineon. It is designed to support Bluetooth LE use cases for home automation, sensors, lighting, Bluetooth Mesh, remote controls and any other Bluetooth LE-connected IoT application, says the company.

The SoC has efficient peripheral design, low leakage silicon with scalable and efficient MIPS, and a low power Bluetooth radio, said Sonal Chandrasekharan, vice president of the Bluetooth product line at Infineon. It is claimed to offer superior RF performance for reliable, robust connections, he added.

The Airoc CYW20829 integrates a power amplifier with 10dBm of transmit output power and has receive sensitivity of -98.5 dBm for LE and -106 dBm for LE-LR 125kbits per second, making it the best link budget in Infineon’s Airoc Bluetooth portfolio. The RF performance offers reliable, robust connectivity without compromising low power, says the company, making the SoC suitable for a range of applications in smart home, smart building, medical, industrial, mesh and human interface devices (e.g., keyboard, mouse, remote control).

The CYW20829 is the first Infineon Airoc Bluetooth SoC to use the Arm Cortex M33. The Bluetooth LE sub system includes an optimised radio and an Arm Cortex M33 core as the Bluetooth controller. A second Arm Cortex M33 with a floating point unit can be clocked up to 96MHz to provide high performance compute at low power.

The application sub system has configurable serial communication blocks that can be turned into UART, I2C or SPI as needed. It also has multiple timer / counter pulse-width modulators, I2S, PDM, CAN and LIN interfaces. For security, there is a ROM-based root of trust, a TRNG, eFuse for custom keys and cryptography acceleration. The SoC also supports XIP from external flash and encryption on the fly for content on the flash.

The AIROC CYW20829 is supported by ModusToolbox – a collection of software and tools for the development of Bluetooth-enabled IoT designs. 

The Airoc CYW20829 Bluetooth LE SoC is currently sampling to select customers.

High resolution radar sensor monitors vehicle’s blind spots

Using a Doppler division multiple access (DDMA)-based signal processing method, the AWR2944 radar sensor can help automotive makers implement systems that can detect vehicles further away than is possible today. The 77GHz sensor has been announced by Texas Instruments and is supplied in a small form factor which it claims is approximately 30 per cent smaller compared to radar sensors today. 

The AWR2944 sensor integrates a fourth transmitter to provide 33 per cent higher resolution than existing radar sensors, enabling vehicles to detect obstacles more clearly and avoid collisions. The DDMA signal processing improves the ability to sense oncoming vehicles at distances up to 40 per cent farther away than is currently possible. 

The high resolution radar sensor will enable driver assistance technology to more accurately monitor blind spots and efficiently navigate turns and corners to safely avoid collisions for improved advanced driver assistance systems (ADAS), says the company.

According to the Federal Highway Administration, more than half of fatal and injury crashes occur at or near intersections or junctions. Texas Instruments says that the AWR2944 radar sensor can help vehicle manufacturers meet new safety regulations, enabling vehicles to detect obstacles more clearly to avoid collisions.    

“Visibility around corners has historically been challenging for autonomous and semiautonomous vehicles,” concedes Curt Moore, manager for Jacinto processors at TI. “For automated parking and driving, being able to see farther with devices like the AWR2944 sensor – and then seamlessly process that data with our Jacinto processors – leads to improved awareness and safety,” he believes.

The AWR2944 and an AWR2944 evaluation module (AWR2944EVM) are available now. 

Texas Instruments (TI) designs, manufactures, tests and sells analogue and embedded processing chips for markets such as industrial, automotive, personal electronics, communications equipment and enterprise systems.

CES is a showcase for Gigabyte’s embedded design support

Edge servers, advanced driver assistance systems (ADAS) as well as motherboards for embedded systems available from Gigabyte, will be highlighted at this week’s CES in Las Vegas.

Its high-density edge servers are based on Arm architecture and Ampere’s 80 / 128- core CPU. They provide the performance, storage, network, and above all, the flexibility to be deployed at more challenging locations and limited spaces, says Gigabyte, which is increasing commonplace as processing work needs to be done on-site.

The speed of the 5G network will allow smart cities to use AI applications, for example transportation systems where edge computers can enhance the communications between devices to ensure traffic flows smoother. Gigabyte says its expertise for embedded computers allow it to have a clear vision of how to implement devices that can work in outdoor environments with stable functionality. These embedded computers come with GPU expandability to meet the needs of edge computing, and rich I/O interface designs to allow system developers to integrate multiple systems on a single platform, therefore developing applications such as licence plate recognition, real-time analytics, smart utility poles and smart traffic management.

Gigabyte also specialises in developing decision-making control units for different types of autonomous vehicles, as well as customised products such as ADAS engine control units (ECUs). The Gigabyte Pilot product series supports GPU and VPU acceleration modules, which combine various algorithms to provide precise object detection, decision-making and vehicle control capabilities. Products in the series are also equipped with high speed transmission interfaces which can be connected to a range of sensing devices to collect and transmit data in real time. 

Gigabyte and MyelinTek have developed a deep learning system called MLSteam, which includes optimised AI software stacking and comprehensive management tools such as resource, container and model management. MLSteam makes it easier for scientists to train and develop AI integration for autonomous vehicles and can make traffic management systems smarter, safer, and more collaborative, says Gigabyte.

The company’s latest embedded computing products feature a series of industrial motherboards and systems powered by Intel’s 11th generation processors. They are intended for factory automation, industry 4.0, smart retail, IoT and edge computing and are characterised by low power consumption. Examples of use are automated guided vehicles, which can be programmed to manoeuvre along designated routes, detect and avoid obstacles through navigation, and also industrial automation security systems. 

AI has also been integrated for visual recognition to upgrade digital signage to detect users’ gender, age to improve retail experiences. Restaurants and delivery services can use electronic control units for smart delivery services, using autonomous vehicles. AI and IoT can also be used to automate the operation and management of public spaces rentals for office, conference, dining and parties.

The Z690 and Aero motherboards will also be highlighted at CES.
