Nordic nRF54L15 Cortex-M33 wireless MCU halves Rx power consumption over nRF52 chips

Nordic Semiconductor has recently unveiled the 128 MHz nRF54L15 Cortex-M33 multi-protocol wireless microcontroller, the first from the nRF54L Series, and the second from the wider nRF54 family after the more powerful 320 MHz nRF54H20 dual-core Cortex-M33 MCU was introduced last Spring. While the nRF54H20 was designed to enable new types of IoT devices with a leap in performance and lots of resources with up to 2 MB flash and 1MB SRAM, the new nRF54L15 aims to be an upgrade to the nRF52 series with twice the performance and much better power efficiency, with for instance, half the Rx power consumption over its predecessor. Nordic Semi nRF54L15 key features and specifications: CPU Arm Cortex-M33 @ up to 128 MHz with up to 1.5 MB Flash + 256 KB SRAM RISC-V coprocessor for “software-defined peripheral” Wireless Bluetooth 5.4 LE with direction-finding, Bluetooth mesh, etc… Ready for future Bluetooth releases 802.15.4 radio for […]

Nordic Semi nRF7001 is a 2.4GHz WiFi 6 companion IC for nRF52, nRF53, and nRF91 wireless chips

Nordic Semi nRF7001 is the second nRF70 Series WiFi 6 companion IC. It is designed to add 2.4 GHz WiFi 6 connectivity to Nordic Semi nRF52 and nRF53 wireless SoCs and nRF91 cellular IoT system-in-package and support both client and access point mode. The nRF7001 follows the introduction of the nRF7002 dual-band (2.4GHz/5GHz) WiFi 6 companion IC last year, and target power or cost-optimized use cases where 5 GHz WiFi 6 may not be required or even suitable. Nordic Semi nRF7001 key features specifications: Complies with 802.11a/b/g/n/ac/ax 2.4 GHz band Wi-Fi 6 Station (STA) 1x Spatial Stream (SS) 20 MHz channel bandwidth 64 QAM (MCS7), 86 Mbps PHY throughput OFDMA (Downlink and Uplink) BSS coloring Co-existence interfaces, including Bluetooth LE Low-power and secure Wi-Fi for the IoT Target Wake Time (TWT) Security – WPA3 Host interface – SPI / QSPI Package – 6×6 mm QFN Since the nRF7001 is based […]

zigpy-zboss library makes Nordic Semi nRF52840 Zigbee dongles compatible with Home Assistant

zigpy-zboss is a Python library that adds support for Nordic Semiconductor nRF52840 modules to zigpy open-source Python Zigbee stack project, as well as other Network Co-Processor radios that run firmware based on ZBOSS Open Initiative (ZOI). This enables integration with compatible Zigbee gateway implementations such as Home Assistant’s ZHA integration component and allows users to directly control Zigbee devices from a wide range of manufacturers such as IKEA, Philips Hue, SmartSung SmartThings, ITEAD SONOFF, Xiaomi Aqara, and others. Home Assistant’s ZHA integration already worked with Zigbee dongles based on Silicon Labs Mighty Gecko EFR32MG21 or Texas Instruments CC2652P microcontrollers, but now it’s possible to use nRF52840 dongles and development as Zigbee Coordinators thanks to the zigpy-zboss library. The zigpy-zboss ZBOSS radio library for zigpy source code and resources can be found on GitHub, but note that this is still an unofficial and experimental port, so testers need to manually […]

Embedded Open Source Summit 2023 schedule – Zephyr OS, Security, IoT, Embedded Linux, and more

The Linux Foundation has just announced the full schedule for the Embedded Open Source Summit, which will take place on June 27-30, 2023 in Prague, Czech Republic, as well as virtually starting on June 26. Over 175 sessions, birds of a feather (BoF) tracks, and workshops related to embedded and open-source innovation will be presented at the event itself comprised of six micro conferences: Automotive Linux Summit Europe, Embedded IoT Summit, Embedded Linux Conference, LF Energy Embedded Summit, Safety-Critical Software Summit, and Zephyr Project Developer Summit. Even though I’m not going to attend personally, I’ve gone through the schedule to create my own little virtual schedule with some sessions relevant that should be interesting to me and hopefully to CNX Software readers. Monday, June 26 (Virtual sessions) The first day of the event will have a Yocto Dev training in the morning, and a bunch of virtual sessions that are […]
