Memory requirements

This page provides information about the amount of flash memory and RAM that is required by the Samples, as well as stack memory requirements for main and zboss threads. Use it to check if your application has enough space for a given configuration. Values are provided for ZBOSS libraries.

Note

This is an experimental release of Zigbee support for the nRF54L Series.

Samples were built using the available ZBOSS Zigbee stack. Unless stated otherwise, the default prj.conf was used.

RAM and flash memory requirements

RAM and flash memory requirement values differ depending on the programmed sample.

The following tables list memory requirement values for Zigbee samples.

Values are provided in kilobytes (KB). n/a indicates that the sample with the given variant is not supported on the DK.

nRF54L15

The following table lists memory requirements for samples running on the nRF54L15 DK (nrf54l15dk).

Sample	ROM, ZBOSS stack + App	ROM, MCUboot bootloader	ROM, ZBOSS non-volatile memory	ROM, ZBOSS product config	Total ROM	RAM, ZBOSS stack + App	Total RAM
Network coordinator	394	0	32	4	430	124	124
Light bulb	418	0	32	4	454	69	69
Light switch	319	0	32	4	355	55	55
Light switch with Multiprotocol Bluetooth LE extension	446	0	32	4	482	72	72
Zigbee application template	392	0	32	4	428	100	100
Zigbee shell	472	0	32	4	508	117	117

Stack memory requirements

The following table lists stack memory requirement values for main and zboss threads. These measurements were carried out with Zephyr’s Thread analyzer, using the following Kconfig options for configuration:

• For the stack memory size of the main thread - CONFIG_MAIN_STACK_SIZE

• For the stack memory size of the zboss thread - CONFIG_ZBOSS_DEFAULT_THREAD_STACK_SIZE

Values are provided in bytes (B).

nRF54L15

The following table lists memory requirements for samples running on the nRF54L15 DK (nrf54l15dk).

Sample	main thread stack usage	main thread stack size	zboss thread stack usage	zboss thread stack size
Network coordinator	872	2048	2056	5120
Light bulb	872	2048	736	5120
Light switch	944	2048	736	5120
