nRF54LM20A System-on-Chip

Ultra-low-power wireless SoC for Bluetooth LE, Matter, Thread, and Zigbee

The nRF54L Series offers SoCs that combine an efficient MCU with ultra-low-power wireless connectivity. The nRF54LM20A provides the largest memory option in the series, with 2 MB NVM and 512 KB RAM. It features an extended set of peripherals, high-speed USB, and is available with up to 66 GPIOs.

nRF54LM20A supports Bluetooth LE, Matter, Thread, Zigbee, and 2.4 GHz proprietary protocols with data rates up to 4 Mbps for low-latency applications. It also supports Bluetooth Channel Sounding, Bluetooth Mesh, Aliro, and Wi-Fi with nRF70 Series companion ICs.

Performance highlights

  • Processing efficiency and performance: 193 CoreMark/mA @ 3 V, 503 CoreMark®
  • Radio power consumption: 3.3 mA for RX and 5.0 mA for TX @ 0 dBm (@ 3 V)
  • Sleep modes power consumption: from 0.7 μA to 4.3 μA (@ 3 V)
  • Maximum TX power: +8 dBm (CSP) / +7 dBm (QFN) 
  • Sensitivity: -96 dBm (1M Bluetooth LE), -101 dBm (802.15.4)
  • Optimized for the lowest total average current


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
  • nRF Cloud support for device management, FOTA and more
