Rutronik Elektronische Bauelemente has expanded its system-on-chip (SoC) portfolio with Nordic Semiconductor’s newest low power chip.
The nRF54LM20A, part of the company’s nRF54L series, aimed at energy-efficient applications, combines a 128 MHz Arm Cortex-M33 processor with a low-power 2.4 GHz radio and scalable memory options.
The nRF54LM20A is designed for a range of consumer and industrial applications, including wearables, gaming peripherals, smart locks, and smart home solutions. It features 2 MB of non-volatile memory, 512 KB of RAM, integrated high-speed USB, and modern security functions, including secure boot, firmware updates, and cryptographic acceleration with side-channel leakage protection.
The SoC also supports multiple protocols such as Bluetooth LE, Matter, Zigbee, Thread, and proprietary 2.4 GHz standards.
Rutronik said that proprietary technologies such as low-leakage RAM and a multi-protocol radio design reduce power consumption, a critical consideration for developers seeking smaller batteries or longer device lifetimes.
The SoC is available in various memory and package configurations, with up to 66 general-purpose input/output pins, including pin-to-pin options for design flexibility.
A corresponding development kit, the nRF54LM20-DK, provides a full functional overview and is supported by the nRF Connect SDK and associated tools, allowing developers to accelerate prototyping. Nordic Developer Academy offers free training to support adoption.
