The latest addition to Infineon Technologies’ AIROC portfolio is the Airoc CYW5551x. This single device combines Wi-Fi 6 / 6E performance and advanced Bluetooth connectivity, making it suitable for a host of IoT applications.

The AIROC CYW5551x Wi-Fi 6/6E and Bluetooth 5.4 family delivers secured, reliable 1×1 Wi-Fi 6 / 6E (802.11ax) connectivity that goes beyond the standard, said Infineon. This is combined with advanced low power Bluetooth connectivity. The optimised CYW55512 is a dual-band Wi-Fi 6 solution and the CYW55513 is a tri-band Wi-Fi 6 / 6E device. Both feature power-efficient designs that are suitable for use in smart homes, industrial applications, wearable devices and equipment and other small factor IoT applications, said the company.

“Infineon’s new CYW5551x family brings the range, reliability, and network robustness from our 2×2 Wi-Fi 6/6E CYW5557x family of devices to an IoT optimised family,” said Sivaram Trikutam, vice president of Wi-Fi Products of Infineon. “As part of the company’s digitalisation and decarbonisation strategy, this family is optimised for very low power consumption, making it ideal for battery-operated devices like wearables and IP cameras,” he said. They are also tuned for best performance across a wide temperature range, enabling them to serve industrial and infrastructure applications such as electric vehicle charging and solar panel controls, logistics.

The AIROC CYW551x family offers support for the 6GHz band for Wi-Fi 6E, delivering lower latency and reduced interference. Bluetooth 5.4 low energy (LE) with Audio is range and power optimised with up to 20dBm transmit power.

Other features include improved multi-layer security (PSA Level 1-certifiable) and design versatility supported by a wide ecosystem of module and platform partners.

The devices feature Linux, RTOS and Android support, and have a fully validated Bluetooth stack and sample code to accelerate development time.

Infineon’s AIROC CYW55512 and CYW55513 are sampling now. The CYW5512 will be commercially available in March 2024, and the CYW55513 will be commercially available in June 2024.

It can be used with USB-C compatible chargers for lithium-ion, lithium polymer, and lithium iron phosphate batteries up to 1000mAh. The nPM1300 has four individually controllable power rails including two high performance buck regulators with a 200mA current limit and two 100mA load switches or 50mA LDOs. The PMIC has an operating temperature range of -40 degrees C to +85 degrees C.

The battery charger complies with JEITA and has a termination range of 3.5 to 4.45V and charge current from 32 to 800mA. The input regulator has an input range of 4.0 to 5.5V and output from 4.0 to 5.5V unregulated. USB current limit is 1500mA and the design includes overvoltage protection at 22V transient.

Other features include an input regulator with USB support, an 800mA charger, ship- and hibernate modes and five general purpose I/Os and three LED drivers.

The nPM1300 PMIC can be used in a choice of applications for wearable devices, handheld entertainment devices, personal health and medical devices and rechargeable smart home sensors.

Integrated, low power, single-chip LCOS panel fits into AR/XR/MR glasses

Fri, Jun 02, 2023

The OP03011 liquid crystal on silicon (LCoS) panel integrates the array and frame buffer into an ultra-compact single-chip solution that is lightweight and low-power for smart glasses

The OP03011 is a single chip, 648p LCoS panel for next generation augmented reality (AR), extended reality (XR) and mixed reality (MR) glasses and head-mounted displays. The LCOS panel features 3.8 micron pixels in what is claimed to be one of the world’s smallest 0.14-inch optical formats. The low power, lightweight design is intended for next-generation glasses that can be worn 24/7, said Omnivision.

The growing interest in AR glasses has led OEMs to design more functionality into slim, fashionable designs that consume very little power and are lightweight, allowing them to be worn for long periods. The OP03011 is designed in a compact format for applications requiring a smaller field of view and lower resolution, making it well suited for some of the sleekest, most innovatively designed AR glasses, said Devang Patel, marketing director for the IoT and emerging segment, Omnivision. “The OP03011 supports applications of next-generation smart glasses, like displaying notifications in the user’s field of view and access to GPS for maps and directions directly from the glasses, so the user never needs to pull out their smartphone,” he said.

The OP03011 features 648 x 648 resolution at 120Hz and comes in a small FPCA package. It supports a single-lane MIPI-DSI interface.

Samples are available now, and the OP03011 will be in mass production in Q4 of 2023.

Omnivision is a fabless semiconductor company that develops advanced digital imaging, analogue and touch and display solutions for multiple applications and industries, including mobile phones, security and surveillance, automotive, computing, medical, and emerging applications.

Battery-operated video camera systems add AI for cloud IoT devices

Thu, May 25, 2023

InnoPhase IoT adds AI and solar panel augmentation to battery-operated video camera system via the Talaria TWO ULP (ultra low power) Wi-fi-optimised reference kit for cloud-connected IP video IoT devices.

In addition to applications such as battery-operated video cameras, smart video doorbells, wearables, smart appliances, home security cameras and in-vehicle dashboard monitoring devices, OEMs and ODMs are introducing new categories of video devices with designs that use solar technology and AI, said InnoPhase IoT.

Based on the Talaria TWO ULP Wi-Fi and Bluetooth Low Energy (BLE) platform, the reference kit consists of dual stack, power optimised software combined with an advanced digital polar radio design to address the challenges involved with yesterday’s power-hungry processing of video IoT designs with a multi-protocol, cloud connected camera system, said the company.

The InnoPhase IoT Talaria TWO wireless platform for video supports up to 2K camera resolution and has an integrated microcontroller which enables off-loading of TCP-IP networking and cloud connectivity stack when ISP (image signal processing) is powered down. An always on, always connected enables low latency and mitigates image loss issues and the low power Wi-Fi at BLE power levels enables a two to four times improvement in battery life.

Until now, untethered wireless cloud connectivity and a long battery life were major design barriers for video IoT. Approximately 10 per cent of video cameras are currently battery-operated primarily because of battery life limitations, reported InnoPhase IoT. Moving to a wireless format wasn’t possible since ubiquitous Wi-Fi is inherently power hungry, rapidly draining video camera’s batteries. The possibility of adding even more features such as AI would mean an even shorter battery life.

The new InnoPhase IoT video reference kit address all of these challenges and provides 40 per cent lower power consumption and a battery life in excess of one year. The company also said it offers device developers a variety of market ready solutions from OEMs and ODMs.

“Using InnoPhase IoT Talaria TWO and an Ingenic T31 integrated reference design, we have been able to build an AI-enabled smart video camera with battery life two to three times longer than today’s solutions. We’re also achieving multi-year battery life when augmented with a solar panel”, said Larry Yang, product manager of smart product line at CE-Link, a wireless video camera OEM. The reference design can be customised, enabling customers to quickly bring branded wireless camera systems to market, he added.

According to Jason Lim, CEO at Kenxen, Taiwan, a smart video camera ODM, the Talaria TWO Wi-Fi / BLE module enables low power, direct-to-cloud connectivity for battery operated cameras. “This allows us to offer quick time to market video products for our end customers,” he added.

InnoPhase IoT president and COO, Wiren Perera, said: “InnoPhase IoT’s Talaria TWO untethers cameras from all wired power and network connections, resulting in more accurate data for cloud processing. It supports the addition of enhanced features such as artificial intelligence and unleashes design creativity only possible with the low-power, long battery-life model.”

The reference kits are currently available for evaluation. Each includes hardware and software integration with an image signal processor, cloud connectivity software and access to ODMs.
