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

nRF54L15

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 […]

Bluetooth NLC (Networked Lighting Control) fully standardizes Bluetooth light bulbs

Bluetooth NLC

Bluetooth NLC (Networked Lighting Control) is a full-stack standard for wireless lighting control from the Bluetooth SIG that will enable multi-vendor interoperability, improve ease of deployment, and offer greater scalability. Bluetooth light bulbs have been around for many years, at first using Bluetooth LE (Radio Layer) and then adding Bluetooth Mesh (Network Layer) to the mix, but there were always some proprietary bits to the software stack, and Bluetooth NLC removes all those with a complete standard for lighting control that further adds Device Profiles specific to his use case. Bluetooth NLC still relies on Bluetooth Low Energy and Bluetooth Mesh, but adds the following NLC Device Profiles at the Device Layer defining the requirements for a range of devices/features: Ambient Light Sensor Basic Lightness Controller Basic Scene Selector Dimming Control Energy Monitor Occupancy Sensor You’ll find the specifications for each profile on the Bluetooth website. While the announcement was […]
