BLE SoCs add processing power for wireless IoT

Compact and ultra-low-power, the nRF54L series supports medical and smart home devices, industrial IoT, gaming controllers, and other IoT applications.

These SoCs feature an Arm Cortex-M33 processor running at 128 MHz. The nRF54L15, the first SoC in the nRF54L series, offers what is said to be a new best-in-class multiprotocol radio and advanced security features.

The processor delivers double the processing power of its predecessor while simultaneously lowering power consumption.

These new SoCs include a 2.4 GHz radio offering up to +8 dBm Tx power in 1 dB increments and -98 dBm Rx sensitivity for 1 Mbit/s Bluetooth LE.

The radio supports all Bluetooth 5.4 features, Bluetooth Mesh, Thread, and Matter, and is equipped for future Bluetooth specification updates.

The nRF54L series also offers hardware architecture built using TSMC's 22ULL process technology to reduce leakage and enhance performance for IoT applications.

The nRF54L series achieves the PSA Certified Level 3 IoT security standard with advanced features, including secure boot, secure firmware update, and secure storage.

Three variants are available: the nRF54L15 with 1,524 KB non-volatile memory (RRAM) and 256 KB RAM; the nRF54L10 with 1,022 KB RRAM and 192 KB RAM; and the nRF54L05 with 500 KB RRAM and 96 KB RAM. The nRF54L series devices are also available in two different packages: a 6 mm x 6 mm QFN or the ultra-compact 2.4 mm x 2.2 mm WLCSP for space-limited designs.

The Nordic Semiconductor nRF54L15 Development Kit is a pre-certified, single-board evaluation and prototyping platform based on the nRF54L. The development kit features a pre-mounted nRF54L15 and can also emulate the nRF54L10 and nRF54L05 wireless SoCs. The affordable single-board development kit makes all features of the wireless SoC series available to the developer.
