nRF54L15, nRF54L10, and nRF54L05 are a part of the nRF54L Series. All wireless System-on-Chip
(SoC) options in the series integrate an ultra-low power, multiprotocol 2.4 GHz radio with MCU
(Microcontroller Unit) functionality featuring a 128 MHz Arm®
Cortex®-M33 processor. nRF54L15, nRF54L10, and nRF54L05 make up a flexible set of SoCs enabling multiple product categories with an extended peripheral set and scalable memory configurations.
Nordic Semiconductor’s proprietary technologies, such as low-leakage RAM and advanced
multiprotocol radio design, enable ultra-low power consumption, reducing battery size or
increasing lifetime.
Designed with versatility in mind, the nRF54L Series SoCs are suited to enable a broad range
of applications. The multiprotocol 2.4 GHz radio supports Bluetooth® LE with optional features including Channel Sounding,
introduced in Bluetooth Core 6.0, as well as
802.15.4-2020 for standards such as Thread®, Matter, and Zigbee®, and a proprietary 2.4 GHz mode supporting up to 4 Mbps for higher
throughput. The devices integrate peripherals expected in a wireless microcontroller, enabling
many products to be implemented with a single chip. An integrated RISC-V coprocessor further
reduces the need for external ICs.
nRF54L15, nRF54L10, and nRF54L05 are available in a range of memory and package
configurations, including pin-to-pin compatible QFN packages, enabling cost-optimized and flexible design across different application requirements.
