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.

nRF54L15nRF54L10nRF54L05

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	367	0	32	4	403	80	80
Light bulb	391	0	32	4	427	64	64
Light switch	292	0	32	4	328	54	54
Light switch with Multiprotocol Bluetooth LE extension	418	0	32	4	454	71	71
NCP	393	0	32	4	429	92	92
Zigbee application template	392	0	32	4	402	74	74
Zigbee shell	445	0	32	4	481	90	90

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).

nRF54L Series

The following table lists memory requirements for the nRF54L Series devices.

Sample	main thread stack usage	main thread stack size	zboss thread stack usage	zboss thread stack size
Network coordinator	872	2048	2192	5120
Light bulb	872	2048	4288	5120
Light switch	944	2048	2120	5120
