BLE Audio Device Firmware

Dual-core Bluetooth 5.4 SoC with dedicated application and network processors. 1MB Flash + 512KB RAM on the application core, with hardware security via ARM TrustZone.

Next-generation ultra-low-power Bluetooth 5.4 SoC with RISC-V and ARM Cortex-M33 cores. Designed for ultra-constrained battery-powered devices.

The flagship nRF54L series SoC built on a 22nm process, featuring a 128 MHz ARM Cortex-M33 + RISC-V co-processor with 2MB Flash and 512KB RAM — the largest memory in the nRF54L family. Supports Bluetooth LE, Matter, Thread, Zigbee, and 2.4 GHz proprietary protocols up to 4 Mbps. The nRF54LM20A variant adds 66 GPIOs and high-speed USB; the nRF54LM20B adds an integrated Axon NPU for hardware-accelerated Edge AI inference. Security includes TrustZone, CRACEN cryptographic engine with side-channel protection, and tamper detection.

High-performance multicore SoC with dual Cortex-M33 (application + radio) plus a RISC-V VPR core. 2MB Flash and 1MB RAM, designed for complex multiprotocol BLE + 802.15.4 applications.
