Nordic Semi nRF54LM20B wireless SoC integrates 128 MHz Axon NPU for Edge AI workloads

nRF54LM20B

Nordic Semi nRF54ML20B Arm Cortex-M33 wireless SoC is the first nRF54L microcontroller to integrate the ultra-efficient Axon Neural Processing Unit (NPU) for edge AI workloads. The NPU is said to deliver up to 7 times faster performance and up to 8 times higher energy efficiency versus (unnamed) competing wireless solutions for tasks such as sound classification, keyword spotting, and image-based detection. The Axon NPU is also about 15x faster compared to using the Cortex-M33 CPU for the same task. Other than the NPU, the nRF54LM20B offers exactly the same features as the earlier nRF54LM20A wireless microcontroller, including up to 2 MB NVM, 512 KB RAM, a 128 MHz Arm Cortex-M33 plus RISC-V coprocessor, high-speed USB, up to 66 GPIOs, and an ultra-low-power 2.4 GHz radio supporting Bluetooth LE, Bluetooth Channel Sounding, Matter over Thread, and more as shown in the nRF54L comparison table below. Like other nRF54L wireless SoCs, the […]

Nordic nRF7002 EBII adds dual-band Wi-Fi 6 to nRF54L series development kits

nRF7002 EBII Wi Fi 6 Expansion Board

Nordic has introduced the nRF7002 EBII as an updated Wi-Fi 6 expansion board for its nRF54L series development kits. The earlier nRF7002 WiFi 6 board was a low-cost add-on for the Thingy:53, mainly for basic prototyping. The new EBII is designed for the newer nRF54L series of SoCs with dual-band Wi-Fi 6 support, power-profiling options, and more. Built around the nRF7002 Wi-Fi Companion IC, it supports Wi-Fi 6 features such as TWT, OFDMA, and BSS coloring for power efficiency and reduced interference. The EBII communicates with nRF54L15 and nRF54LM20 DKs through SPI/QSPI host interfaces, and includes headers for power profiling. Additionally, it features an onboard chip antenna, supports both STA and SoftAP modes, and maintains backward compatibility with 802.11a/b/g/n/ac. These features make it suitable for low-power multiprotocol IoT devices in smart homes, Matter, industrial sensing, wearables, and connected health applications. nRF7002 Expansion Board II specifications: Wi-Fi Companion IC – Nordic nRF7002 […]
