BL54L15 Series - Bluetooth LE + 802.15.4 + NFC

Overview

Experience a new pinnacle of performance, efficiency, and security with our new BL54L15 series, built on Nordic Semiconductor's powerful nRF54 silicon. Elevating what you know and love from the nRF52 series, this next generation redefines Bluetooth LE and 802.15.4 solutions. Unleashing enhanced processing power, expanded memory, and innovative peripherals, the BL54L15 is the ultimate choice for low power connectivity. Powered by the Nordic's nRF54L15 SoC, our compact BL54L15 modules deliver secure and robust Bluetooth LE and 802.15.4 with flexible programming via Canvas Software Suite, Nordic SDK or Zephyr RTOS. 

Featuring a 128MHz ARM Cortex M33 and 128MHz RISC-V coprocessor, supported by 1.5 MB non-volatile memory and 256 KB RAM, the BL54L15 modules offer double the processing power (vs prior BL654 – nRF52840). The BL54L15 series brings out all nRF54L15 hardware features and capabilities including up to +8 dBm transmit power, 1.7V – 3.6V supply considerations, and NFC A-Tag implementation It’s further enhanced with state-of-the-art security and is designed for PSA Certified level 3 and supports services such as Secure Boot, Secure Firmware Update, Secure Storage plus protection from physical attacks.

  • Nordic nRF54L15 – 6x6 QFN48 with 31 GPIOs utilized. 
  • Antenna choice – integrated pre-certified PCB Trace antenna or external antenna support via MHF4 connector
  • Ultra-small footprint (14 mm x 10 mm x 1.6 mm) 
  • Development choice: Canvas Software Suite, Zephyr RTOS or Nordic nRF Connect SDK 
  • Firmware Over the Air (FOTA) via MCUboot and Zephyr
  • Hostless operation – Multi Core MCU reduces BOM
  • Fully featured development kits to jump start Bluetooth LE development
  • Mechanically same form factor as BL652 Series
