Nordic Semiconductor has extended its nRF54L series of ultra-low-power wireless SoCs with the introduction of the nRF54LM20A. The new wireless SoC offers developers greater resources and flexibility, extending battery life for advanced connected products across consumer, industrial, and healthcare markets.
The nRF54LM20A is part of the nRF54L series, joining the nRF54L15, nRF54L10, and nRF54L05 devices. Based on Nordic’s 22-nm platform, the nRF54LM20A offers the largest memory option with 2-MB NVM and 512-KB RAM, while maintaining the same microcontroller with a 128-MHz Arm Cortex-M33 processor and RISC-V coprocessor. It also extends the peripheral set with high-speed USB and up to 66 GPIOs, and offers seven serial interfaces (including SPI, TWI, UART, and HS-SPI). Advanced security features include TrustZone isolation, tamper detection, and cryptographic engine with side-channel leakage protection.

The new wireless SoC integrates Nordic’s fourth-generation ultra-low-power 2.4-GHz radio, supporting a range of protocols such as Bluetooth LE (including Channel Sounding), Matter over Thread, and Zigbee. Like the other wireless SoCs in the nRF54L Series, the nRF54LM20A delivers twice the processing power, three times the processing efficiency, and up to 50 percent lower power consumption than the nRF52 Series, Nordic said.
The nRF54LM20A is designed for advanced wireless products in consumer, smart home, commercial, and industrial segments. It also can be used in human interface devices, including gaming peripherals that require low-latency wireless connectivity and high-speed USB. It is also particularly suited for smart home devices, such as a Matter implementation, providing the necessary overhead for the application without requiring external memory.
The nRF54LM20A, available in ultra-compact CSP and QFN packages, is ready for development. Samples and development kits can be requested through Nordic’s project-based early access program. The nRF54LM20A is supported by Nordic’s nRF Connect SDK for developing scalable, low-power, and secure IoT applications. Production is expected to start in the first quarter of 2026.
