Software evaluation for nRF54L15

[Tom.Fu]

Hi Support Team

Our project needs to support the following features:
 1 BLE central role, 1 BLE peripheral role
 1 PWM, 1 UART, 1 ADC
 OTA  and BLE bonding

Can the nRF54L15 meet these requirements? what is the minimum Flash and RAM size required?

Many thanks

Hi Tom,

All the features mentioned above is supported in the nRF54L05 as well.. 512 KB Flash and 96 KB RAM may be sufficient for your use case, but if your application is complex, you may approach the memory limits. If you need more headroom, I would still recommend you to consider nRF54L10 or nRF54L15, which offer more memory.

If your application is too large, you will run out of memory and cannot use OTA DFU without external flash or a larger device.

Regards,

Swathy

Hi SwRa 

I enable OTA in the peripheral_uart sample. But the flash is overflowed by 6300bytes after I built this sample for nRF54L05. Is there any approach to optimize the memory usage for nRF54L05? Many thanks.
