Omnivision debuts industry’s smallest-footprint sensor for presence detection

Tue, Nov 05, 2024

Omnivision has announced the new OV0TA1B monochrome (mono)/infrared (IR) CMOS image sensor, the first and only solution that fits 3mm module Y dimension and smaller notebook computers, webcams and IoT devices. The OV0TA1B is a low-power device that is ideal for artificial intelligence (AI)-based human presence detection (HPD), facial authentication and always-on (AON) technology.

“Stand-alone 940nm IR cameras are becoming more mainstream, especially in the latest generation of ultrathin-bezel design notebooks that feature personalised AI features and require HPD and facial authentication capabilities,” said Jason Chiang, staff marketing manager computing, Omnivision. “The OV0TA1B is the newest mono/IR sensor in our computing portfolio designed to be a cost-effective, ultra-small-footprint device; it is ideal for HPD and facial authentication in 3mm module Y bezel and smaller designs. The ultra-small size of the OV0TA1B sensor also makes it useful for webcams and IoT devices, like those used for people and traffic counting.”

The OV0TA1B comes in either IR or mono, depending on the customers’ design needs (in cases where the system has another stand-alone RGB camera). It features a 2-micron (µm) pixel based on PureCel pixel technology for high-performance sensitivity and MTF (modulation transfer function), allowing it to maintain the HPD and facial authentication.

The OV0TA1B delivers 440 x 360 resolution at 30 frames per second (fps). It is a low-power 220×180 (2.58mW@3fps) image sensor in a 1/15.8-inch optical format. https://www.ovt.com

Innodisk’s DDR5 6400 series integrates several advanced technologies to ensure stable, uninterrupted performance:

• Client Clock Driver (CKD): Enhances signal integrity by buffering clock signals, which is essential for minimising noise and ensuring accuracy during high-frequency data transfers.
• Transient Voltage Suppressor (TVS): Offers robust protection against voltage fluctuations, safeguarding sensitive components.
• eFuse Circuit Protection (RDIMM): Designed to interrupt the circuit in case of overvoltage, preventing damage to components in server systems with higher voltage requirements.
• Wide Industrial Temperature Range: The DDR5 6400 series is designed to operate in temperatures from 0°C to 95°C (Tc) and will soon support an extended range of -40°C to 95°C (Tc), making it ideal for challenging industrial environments.
• Anti-Sulfuration Protection: 30μ” gold plating protects against sulfurisation, ensuring long-term durability.

The DDR5 6400 series is fully compatible with the latest Intel and AMD processors and supports a range of options—CUDIMM, CSODIMM, ECC CUDIMM, ECC CSODIMM, and RDIMM—with capacities from 8GB to 64GB, giving users flexible configurations for varied use cases.

Beyond cloud-based AI, Innodisk’s DDR5 6400 memory modules are ideal for next-generation edge AI applications, where real-time responsiveness and enhanced security are crucial. For instance, smart factories can leverage LLMs to consolidate and manage complex production data instantly, supporting swift decision-making. In remote healthcare, high-resolution 3D imaging and real-time data analysis empower precise, remote surgical procedures for patients. In releasing the DDR5 6400 series, Innodisk reinforces its commitment to delivering innovative memory solutions that drive advancements in AI, telehealth, and industrial automation.

Renesas introduces new RX261/RX260 group of MCUs

Wed, Oct 23, 2024

Renesas has introduced the RX261 and RX260 microcontroller (MCU) Groups. The new 64 MHz MCUs deliver power efficiency of only 69μA/MHz during active operation and 1μA in standby mode. They also enable designers to easily implement water-resistant capacitive touch sensors and deliver robust security. This combination of performance and features position the RX261/RX260 Group MCUs for applications such as home appliances, building and factory automation, and many others including smart locks, e-bikes and mobile thermal printers.

The RX261/RX260 Group MCUs are based on Renesas’ RXv3 CPU core, enabling 355CoreMark at 64MHz. This score is 2.5 times higher than competing 64-MHz class MCUs. Compared to other 64-MHz class MCUs, the RX261/RX260 also delivers 25 percent lower active current and 87 percent lower standby current. This outstanding power efficiency minimises current consumption during intermittent operation. These low power features help customers meet strict energy regulations for home appliances and extend the operating time of battery-powered applications.

Renesas’ third-generation capacitive touch IP (CTSU2SL) delivers high noise immunity and water resistance, allowing users to implement touch sensors in kitchen appliances and outdoor equipment such as smart locks. The automatic judgement function reduces current consumption during intermittent operation by enabling touch detections even in standby state. The QE for Capacitive Touch tuning tool, design guides, and sample programs ease the implementation of touch sensors in multiple applications.

Today, many consumer and industrial systems offer wireless connectivity features such as Bluetooth and/or Wi-Fi to enable smartphone controls or to download new firmware from cloud servers. By implementing security features with the Renesas Secure IP (RSIP-E11A) and flash protection functions, users can protect their applications from unauthorised use such as data falsification and eavesdropping by attackers. Sample programs help users to implement secure boot and secure firmware update functions quickly and easily.

The RX261 Group MCUs provide a wide range of features, including a Full Speed USB function controller with a high-speed on-chip oscillator (HOCO) that eliminates the need for external crystals to generate an accurate USB clock. A CAN FD module is also included to enable fast and reliable communication. Unlike some other MCUs, the RX261/RX260 Group MCUs include 8 KB data flash enabling customers to eliminate the need for an external EEPROM.
