Reference circuitry

To ensure good RF performance when designing PCBs, it is highly recommended to use the PCB layouts and component values provided by Nordic Semiconductor.

Documentation for the package reference circuits, including Altium Designer files, PCB layout files, and PCB production files can be downloaded from www.nordicsemi.com.

In this section, there are reference circuits for all product variants, showing the components and component values to support on-chip features in a design.

PCB layout example

The PCB layout in the following figure is a reference layout for Circuit configuration 1 for QFN48 (QFAA).

Note: Pay attention to how the capacitor C7 is grounded. It is not directly connected to the ground plane, but grounded via pin 33 and to the VSS die pad. This is done to create additional filtering of harmonic components.
For all available reference layouts, see the product page for nRF54LC10A on www.nordicsemi.com.

PMIC support

The nRF54L Series is comprehensively supported by Nordic Semiconductor's own range of PMICs (Power Management Integrated Circuits). These PMICs are meticulously designed to enhance the performance and efficiency of the nRF54L Series devices. This integration ensures the longest battery life and the highest reliability for the end application. The synergy between the nRF54L Series and the Nordic PMICs highlights Nordic Semiconductor's commitment to providing a complete and cohesive solution for their customers' needs in wireless technology applications.
