PTR54LM20B is a wireless module designed for high-performance IoT terminals, low-power wireless systems and edge intelligence scenarios. Based on the Nordic nRF54LM20B, the module integrates one Arm Cortex-M33 main processor, one RISC-V coprocessor and one Axon Neural Processing Unit (NPU), with a maximum operating frequency of 128 MHz. As a highly efficient AI hardware accelerator, the Axon NPU can boost on-device AI inference speed and energy efficiency up to 15 times compared with using a CPU alone. The processors are optimized for specific workloads, balancing computing power, energy efficiency and edge intelligence processing capabilities. The module is equipped with large-capacity high-speed memory, which readily supports complex applications, machine learning and edge sensor fusion. Combined with the Axon NPU, it further unlocks the potential of edge intelligence. It features a built-in high-speed USB interface for high-speed data transmission, convenient debugging and firmware updates. Supporting up to 66 GPIOs, it delivers strong peripheral expansion capabilities and can flexibly adapt to hardware access requirements across diverse scenarios. In addition, the module incorporates a comprehensive security framework that effectively defends against various security threats, fully meeting the stringent performance, functional and scalability requirements of high-end BLE devices, smart home applications, industrial applications and edge intelligent terminals. The PTR54LM20B module simplifies design, reduces costs and accelerates time-to-market. Backed by professional design, strict quality control and relevant certifications, it enables customers to quickly launch edge AI-enabled products to the global market with complete peace of mind.
