BL54L15μ Series - Bluetooth LE + 802.15.4 + NFC

Experience a new pinnacle of performance, efficiency, and security with our new BL54L15µ 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 BL54L15µ is the ultimate choice for low power connectivity, in the smallest footprint (6.3 x 7.9 mm). 

Powered by Nordic's nRF54L15 (WLCSP 300um) SoC, our ultra compact BL54L15µ modules deliver secure and robust Bluetooth LE and 802.15.4 with flexible programming via the Nordic SDK, Zephyr RTOS and Canvas Software Suite.

Featuring a 128MHz ARM Cortex M33 and 128MHz RISC-V coprocessor, supported by 1.5 MB non-volatile memory and 256 KB RAM, the BL54L15µ modules offer double the processing power (vs prior BL654 – nRF52840). The BL54L15µ 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. It supports services such as Secure Boot, Secure Firmware Update, Secure Storage plus protection from physical attacks.
