Nordic Semiconductor expands the nRF54L Series with nRF54LM20A, a high-memory wireless SoC for advanced Bluetooth LE and Matter applications
Nordic Semiconductor, a global leader in low power wireless connectivity solutions, today announced the launch of the nRF54LM20A, the latest addition to its next-generation nRF54L Series of ultra-low power wireless SoCs. Built on Nordic’s innovative 22nm technology platform, the nRF54L Series simplifies design challenges while enabling reliable communication, extended battery life, and compact product designs.
Comments
“The nRF54LM20A opens up more opportunities for developers to build innovative connected products demanding more memory, interfaces, and performance,” says Oyvind Strom, EVP Short-Range at Nordic Semiconductor. “This product launch signifies the next step in delivering a comprehensive nRF54L Series portfolio to cover a broad range of applications – marking the nRF54L Series as the front-runner in the industry.”
Expanding the nRF54L Series as adoption accelerates
The nRF54LM20A expands the nRF54L Series with a high-memory option, featuring 2 MB NVM and 512 KB RAM, while maintaining the same MCU functionality with a 128 MHz Arm Cortex-M33 processor, RISC-V coprocessor, and enhancing the comprehensive peripheral set with high-speed USB and up to 66 GPIOs. It also integrates Nordic’s fourth-generation ultra-low-power 2.4 GHz radio, supporting Bluetooth® LE, Channel Sounding, Matter over Thread, and more. 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 industry reference – the nRF52 Series.
Designed for demanding applications
The nRF54LM20A is designed for advanced wireless products across markets, including consumer, smart home, commercial, and industrial. It is particularly well-suited for Human Interface Devices (HID), including gaming peripherals that require low-latency wireless connectivity and high-speed USB. With 2 MB of non-volatile memory and 512 KB of RAM, it’s ideal for smart home devices – such as a Matter implementation – offering ample overhead for the application without requiring external memory.
Developer-friendly software support
The nRF54LM20A is supported by Nordic’s nRF Connect SDK, offering an easy-to-use framework for developing low-power and secure IoT applications that can scale from simple use cases to feature-rich and innovative implementations. The nRF Connect SDK is based on the Zephyr project combined with Nordic software, bringing together the best of open source and ultra-optimized software with Nordic’s proprietary features and technology. This powerful package offers a no-compromise solution for developers to extract the most out of devices such as the nRF54LM20A.
Seamless PMIC integration
For developers with demanding wireless designs that require maximum energy efficiency and extended battery life, Nordic’s family of Power Management ICs (PMICs) is designed to work seamlessly with the nRF54L Series SoCs. In addition to power efficiency gains, integrating a Nordic PMIC can reduce system complexity, Bill-of-Materials (BOM), and board space.
Availability
The nRF54LM20A is ready for development. Development kits and samples can be requested through Nordic’s project-based early access program. Developers are encouraged to contact Nordic sales to initiate projects and begin development with the nRF54LM20A. Production is expected to start in Q1 2026.
