Compact, low power, NB-IoT industrial modules have GNSS geo-location capability

Fri, Feb 24, 2023

Programmable, certified LTE Cat NB2 NB-IoT industrial modules, the SR87M01 series announced by STMicroelectronics, cover worldwide cellular frequency bands and integrate advanced security features.

The low power modules combine reliable and robust NB-IoT data communication with accurate and resilient GNSS geo-location capability for IoT devices and assets.

According to ST, the ST87M01 is one of the first IoT cellular products worldwide offered in accordance with the latest 3GPP Release 15. It provides extended multi-regional LTE coverage. The integrated native GNSS receiver with multi-constellation access delivers localisation with power saving features while operating during NB-IoT sleep time slots.

The module has dimensions of just 10.6 x 12.8mm and is in an LGA package.

It is qualified over the industrial temperature range (-40 to +85 degrees C), with low power consumption of less than 2.0 microA in low power mode. Output power is up to +23dBm. The ST87M01 targets wide-ranging IoT applications that require reliable low power wide area network (LPWAN) connectivity, such as smart metering, smart grid, smart building, smart city and smart infrastructure applications, as well as industrial condition monitoring and factory automation, smart agriculture and environmental monitoring. It is also suited to tracking applications such as locating pets, children, and elders, safety monitoring for remote workers, asset tracking for equipment such as power tools, and general intelligent logistics.

The STM8701’s programmable IoT platform lets users embed their own code directly in the module for simple applications. Alternatively, the module can be combined with a separate host microcontroller, for more sophisticated use cases. A variety of protocol stacks is available to handle popular IoT use cases, including IPv6, TCP/UDP, CoAP/LWM2M, MQTT, HTTP/HTTPS and TLS/DTLS. The ST87M01 is designed to support both standardised 3GPP AT commands and ST enhanced AT commands.

An ST4SIM embedded SIM (eSIM) is integrated in the module. This is certified according to the latest industry standards, including GSMA eSA (Security Assurance) certification and includes an embedded secure element (eSE).

The ST87M01 is sampling now to major customers worldwide.

NXP integrates NFC in lock for Matter devices

Thu, Feb 23, 2023

The EdgeLock SE051H is a secure element designed for the Matter protocol by NXP Semiconductor. It integrates NFC (near field communication) functionality to simplify secure onboarding of Matter devices in the smart home, said the company.

The latest addition to NXP’s portfolio of Matter devices, the EdgeLock SE051H is a single chip with integrated NFC, designed to simplify the secure and seamless onboarding of Matter devices. It can also enable new smart home user experiences, such as suggested automations, installation videos and other content with just the tap of an NFC-enabled phone.

The Matter standard, designed by the Connectivity Standards Alliance (CSA), is designed to ease device interoperability challenges within the smart home network. It raises smart home security with features such as cryptographic keypairs, digital certificates, and other security-related hardware and firmware requirements to protect smart home devices. The EdgeLock SE051H is optimised to support these requirements.

“The single-chip EdgeLock SE051H makes it easy for developers to secure their Matter-certified smart home devices, while integrated NFC improves the end user Matter experience and allows device makers to differentiate based on that user experience,” observed Philippe Dubois, senior vice president and general manager, secure transactions & identification, NXP.

The EdgeLock SE051H is Common Criteria EAL 6+ certified and supports the cryptographic operations needed for a Matter-certified smart device. This includes Matter device attestation and certificate-based authentication with ECC cryptography and NIST P-256 curve, as well as the SPAKE2+ algorithm for password authenticated key exchange. It also includes key security functions such as ECDSA, ECDH, and True Random Number Generator to protect the Matter protocol. In addition, the EdgeLock SE051H has an integrated NFC interface and Type-4 Tag capability.

Matter’s security requirements include a device attestation certificate, which confirms device authenticity, demonstrates trustworthiness and establishes an authenticated connection with the larger Matter network. NXP is one of the first semiconductor manufacturers to have been granted trusted Product Attestation Authority status by the CSA, with its EdgeLock 2GO service for securely provisioning IoT devices. EdgeLock 2GO, combined with EdgeLock SE051H, can pre-inject credentials directly into silicon at silicon manufacturing or can deliver the credentials securely over-the-air (OTA) with end-to-end security to simplify supply chain management and in compliance with the Matter standard.

Network emulator for RF and RedCap is released by Keysight

Thu, Feb 23, 2023

Designed specifically for all cellular IoT (CIoT) technologies, including the 5G RedCap specification, the E7515R is Keysight Technologies’ wireless test platform for chipset, device and module makers. The network emulation platform supports the development workflow from early design and development to deployment, said Keysight.
The E7515R is based on the company’s 5G Network Emulation Solutions platform, a streamlined network emulator specifically designed for protocol, radio frequency (RF), and functional testing of all CIoT technologies.
The E7515R features streamlined capabilities for RedCap without the additional features needed to test a full-spec 5G device. The integrated platform combines RF, protocol, functional, and performance testing in a compact footprint.
The 5G RedCap specification introduces support for wireless devices with reduced 5G capabilities. These devices are less complex, and consume less power, allowing them to address new CIoT use cases such as industrial sensors and wearables such as smartwatches. Like other cellular devices, RedCap devices require time-consuming and expensive certification from accredited labs before they can be released to the market. By performing lab validation early, to identify and correct design issues, device and module manufacturers can shorten the certification process for RedCap and other CIoT devices, said Keysight.
The E7515R supports 5G Release 17 RedCap and legacy CIoT technologies, including Narrowband IoT (NB-IoT), LTE Category M, and LTE Cat-1bis.
The E7515R is built on the same architecture as Keysight’s 5G Network Emulation Solutions platform. The E7515R also uses the same software, providing workflow consistency and reduced learning curves.
The E7515R is shipping now and Keysight will demonstrate the solution’s 5G RedCap network emulation capabilities at MWC 2023 in Barcelona (27 February to 02 March): Hall 5 Stand 5E12.
Keysight delivers design and validation products across the development lifecycle, in design simulation, prototype validation, automated software testing, manufacturing analysis, and network performance optimisation and visibility in enterprise, service provider and cloud environments. Customers span the worldwide communications and industrial ecosystems, aerospace and defence, automotive, energy, semiconductor and general electronics markets.

The class II insulation parts are rated for harsh over-voltage category III (OVC III) and pollution degree 3 (PD3) environments up to 5000m altitude. Safety certifications include audio/video, IT, test equipment, industrial, household, and MOPP medical, with 4kVAC/1 min, rated isolation. The RACM30-K/277’s no-load / standby dissipation meets eco-design requirements with near-flat efficiency curves down to light loads, reported Recom. All parts meet Class B EMC standards with a wide margin without external components, even with grounded outputs.

The RACM30-K/277 series uses silicon-free encapsulation and is offered as a board-mount module with an industry-standard pinout. Optionally, the parts are available with flying leads or as panel-mounted with clip accessories to enable DIN-rail mounting.
