nRF54L15 wireless SoC integrates an ultra-low-power multiprotocol 2.4 GHz radio and MCU (Microcontroller Unit) functionality, featuring a 128 MHz Arm Cortex-M33 processor and comprehensive peripheral set. The series offers a selection of packages and memory size options with pin-to-pin compatible QFN packages.

nRF54L15 is suitable for products using Bluetooth Low Energy, Bluetooth Mesh, Zigbee, Thread, Matter, Amazon Sidewalk, and proprietary 2.4 GHz protocols. In addition, it can run a Wi-Fi stack for the nRF70 Series companion ICs.

nRF54L15 is the largest memory option in the nRF54L Series, with 1.5 MB NVM and 256 KB RAM, for more demanding applications, while still being cost-optimized for high-volume applications.

nRF54L15 supports Bluetooth Low Energy 6.0, including Channel Sounding (supported in nRF Connect SDK v3.0.1 and later). The standard and additional Bluetooth LE features are supported, including the networking capabilities of Bluetooth Mesh with accompanying Bluetooth NLC (Networked Lighting Control) profiles, and Bluetooth PAwR (Periodic Advertising with Responses) with the ESL profile. All nRF54L wireless SoCs are multiprotocol, supporting Matter and IEEE 802.15.4-2020 based protocols, including Thread and Zigbee, which can be used together with Bluetooth LE for use cases such as secure provisioning or DFU. Ecosystems such as Amazon Sidewalk, Google Find My Device, and Apple Find My are also supported and available with the nRF Connect SDK. In addition to standardized protocols, nRF54L Series supports the implementation of proprietary 2.4 GHz protocols with the new 4 Mbps mode. Additionally, the nRF54L15 can run a Wi-Fi stack for the companion ICs from the nRF70 Series.

The nRF54L15 is available in a WLCSP package for demanding and size-constrained products.
