nRF54LS05A and nRF54LS05B are 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. nRF54LS05A and nRF54LS05B support Bluetooth® LE and proprietary 2.4 GHz protocols.
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 devices integrate the peripherals expected in a wireless microcontroller, enabling a variety of products to be implemented with a single chip.
nRF54LS05A and nRF54LS05B are available in a range of pin-to-pin compatible QFN package options, enabling cost-optimized and flexible design across different application requirements.
