Pioneering SoCs for next-gen (I)IoT applications

The nRF54L SoC is a significant addition to the nRF54 series and the successor to the highly popular as well as in-demand nRF52 series. Higher performance, efficiency, and security make this recently launched product the optimal and future-proof choice for realising the next generation of wireless IoT products.

All SoCs in the nRF54L series offer MCU functionality with a 128MHz Arm Cortex-M33 processor, doubling the processing power and tripling the processing efficiency – compared to the nRF52840. This enables enhanced functionality in end products while consuming up to three times less power.

Security is one of the key challenges in the (I)IoT environment, which is why Nordic Semiconductor relies on advanced security features with physical protection for the nRF54L series: secure booting, secure firmware updates, secure storage, as well as a TrustZone-enabled trusted execution environment, a cryptographic accelerator with side-channel leakage protection and tamper detectors, already allow the development of applications that will meet future security regulations.

The hardware and software highlights of the nRF54L series compared to the predecessor flagship nRF52 (nRF52840):

Significantly better specifications in terms of:

• Arm Cortex-M33 (128MHz), instead of Arm Cortex-M4 (64MHz)
• 1.5MB NVM / 256KB RAM, instead of 1MB Flash/256KB RAM
• Bluetooth LE version 6.0 and higher, instead of Bluetooth LE version 5.4

Further benefits:

• Non-volatile memory: 1.5MB (nRF54L15) // 1.0MB (nRF54L10) // 0.5MB (nRF54L05)
• 256KB RAM (nRF54L15) // 192KB RAM (nRF54L10) // 96KB RAM (nRF54L05)
• Ultra-low power multiprotocol 2.4GHz radio: Bluetooth Low Energy, Bluetooth Mesh, Bluetooth Channel Sounding, Zigbee, Thread, Matter, proprietary 2.4GHz protocols, and support for ecosystems such as Amazon Sidewalk, Google Find My Device, and Apple Find My
• RISC-V co-processor and integrated peripherals: new real-time global clock, also available when the system is switched off, 14-bit analogue-to-digital converter and high-speed serial interfaces
• PSA Level 3 certified
• Design flexibility and pin-to-pin compatibility

Application examples:

• Smart home and Matter, smart wearables, VR/AR,
• PC peripherals, HID, remote control
• (Industrial) IoT, building automation, access control
• Medical / healthcare, fitness
