nRF54LS05A

Entry-level, ultra-low-power Bluetooth LE SoC

The nRF54L Series offers SoCs that combine an efficient MCU with ultra-low-power wireless connectivity.

 

The nRF54LS05A and the larger-RAM option nRF54LS05B feature a Bluetooth LE radio and an entry-level peripheral set making them suitable as a main MCU for simple products such as, sensors, tags, beacons, remotes, and PC peripherals, as well as a Bluetooth companion device in larger systems alongside a larger MCU.

 

nRF54LS05A supports Bluetooth LE and 2.4 GHz proprietary protocols with data rates up to 4 Mbps for low-latency applications.
