SoM powers AI-enabled cameras

Thu, Nov 11, 2021

A system on module (SoM) by Smart Wireless Computing, the Inforce 6403, is based on Qualcomm’s QCS610. It enables advanced visual computing for AI-enabled surveillance camera and edge appliances, connected body cameras, smart displays, and other IoT wireless network edge devices, says the company.

Engineers can use the Inforce 6403 SoM to bring on-device AI and machine learning (ML) to cameras and displays, while enabling multiple connectivity options for critical data transfer.

It supports 4K UltraHD (HEVC) video capture and playback to enable video analytics applications integrated into smart cameras, such as face detection and object tracking. High-bandwidth connectivity options include Ethernet RGMIII, 802.11nac Wi-Fi, Bluetooth 5.x, USB-C, and LTE Cat 4 via a carrier board.

The compact LGA package measures just 43 x 32.5mm (1.69 x 1.28 inches), allowing it to integrate into camera housings and systems, particularly in applications where a soldered connection is required for a rugged end-product.

The module comes with a software package that includes integration with Google Firebase and a sample application to upload or stream videos in real time. Google Firebase is a unified backend-as-a-service (BaaS) platform for mobile and web developers that integrates with other Google services.

The Qualcomm QCS610 SoC integrates a Qualcomm Kryo 460 CPU with independent efficiency and power clusters. There are also dual 14-bit Qualcomm Spectra 230 image signal processors which support up to 24Mpixels for simultaneous concurrent cameras capturing sharp images.

The Qualcomm Adreno 612 GPU provides efficient rendering of advanced 3D graphics.

The SoC also leverages Qualcomm Hexagon Vector eXtensions (HVX) on Hexagon 685 DSP enable accelerated machine learning through deep neural network models and with advanced Qualcomm neural processing engine SDK support and TensorFlow Lite.

A secure processing unit enables secure boot, DRM and content protection for a secure environment for the camera system.

The Inforce 6403 SoM incorporates enhanced EMI shielding for RF noise protection, while also improving heat dissipation to improve performance.

A reference design based on the SoM is available.

NFC Type 2 tag IC has permanent write locks and configurable kill mode

Thu, Nov 11, 2021

Consumer engagement, production information and brand protection are offered with the ST25TN512 and ST25TN01K NFC Forum Type 2 tag ICs by STMicroelectronics. They can also be used for access control.

The ST25TN512 and ST25TN01K NFC tag ICs support multiple user-protection and privacy mechanisms including a 7-bit unique chip-identifier code, TruST25 digital signature, NFC Forum T2T permanent write locks at block level, and a configurable kill mode that permanently deactivates the tag.

The two ICs are certified to NFC Forum Type 2 specifications and leverage ISO 14443 standards. They can be used with NFC-compatible mobiles or a dedicated short-range reader. The embedded device memory includes up to 208 bytes (1664 bits) dedicated to user content.

There is also support for messages in NFC data exchange format (NDEF) which triggers native actions on a smartphone without needing a dedicated app, such as launching a web browser or starting Bluetooth pairing. Augmented NDEF (ANDEF) enables reading dynamic information such as custom messages and unique tap codes without explicitly updating the EEPROM.

The ST25TN512 and ST25TN01K are produced by a new in-house manufacturing process. Both NFC tag ICs contain an internal tuning capacitance of 50pF, which allows plug-and-play integration by inlay manufacturers. The tags harvest energy from the 13.56MHz RF transmitter field and require only an antenna to complete the design.

They also have a long data retention and operate over a wide temperature range of -40 to +85 degrees C. The ICs can be supplied in sawn and bumped wafer format or housed in a DFN5 package.

Both the ST25TN512 and ST25TN01K are available in volume production.

High inrush capability relay protects smart lighting controls

Wed, Nov 10, 2021

Smart building automation systems require a high inrush performance, which has prompted the design of the G5RL-EL latching relay by Omron Electronic Components Europe.

The low profile power relay controls capacitive loads and is suitable for controlling fluorescent and LED lamps. Its single contact structure makes it a competitive product proposition, says the company.

The 16A G5RL-K-EL latching type relay is approved to IEC60669-1 and has a high inrush current capability up to 255A. This equips it for demanding switching environments where loads vary enormously. The device is also compatible with the International Safety Standard for Electrical / Electronic Household Appliances (IEC60335-1). The latching design saves energy as there is no hold current to keep the relay open.

The device expands Omron’s G5RL relay family. Andries de Bruin, senior European product marketing manager at Omron, observed: “Smart building systems can reduce the need to touch shared surfaces – an important safety measure as we return to working life after COVID-19. So, facilities managers are increasingly turning to automated lighting to increase safety as well as save energy”. He adds that the highly variable loads typical of these systems demand specialist components and that the G5RL-K-EL “is a smart solution to this growing challenge”.
