nRF54L05 System-on-Chip

Ultra-low-power wireless SoC

The nRF54L Series offers SoCs that combine an efficient MCU with ultra-low-power wireless connectivity. The nRF54L05 provides a smaller memory option in the series, with 0.5 MB NVM and 96 KB RAM. It features an extended set of peripherals, and is pin-to-pin compatible with nRF54L15 and nRF54L10, enabling seamless design flexibility.

nRF54L05 supports Bluetooth LE, Thread, Zigbee, and 2.4 GHz proprietary protocols with data rates up to 4 Mbps for low-latency applications, Bluetooth Channel Sounding, and Bluetooth Mesh.

Performance highlights

  • Processing efficiency and performance: 193 CoreMark/mA (@ 3 V), 503 CoreMark®
  • Radio power consumption: 3.4 mA for RX and 4.8 mA for TX @ 0 dBm (@ 3 V)
  • Sleep modes  power consumption : from 0.7 μA to 1.7 μA (@ 3 V)
  • Maximum TX power: +7 dBm (QFN) 
  • Sensitivity: -96 dBm (1M Bluetooth LE), -101 dBm (802.15.4)


Key benefits

  • Reduced design complexity, size, and cost
  • Reliable and robust wireless connectivity
  • Extended battery life enabled by lower power consumption
  • Built-in security features supporting compliance with regulations
  • Broad range of MCU feature sets across the series
