Is there an Apollo3 unique ID available through the Arduino Core?

Is there a unique ID (UUID or similar) available with the Apollo3 chip that is accessible through the Arduino Core?

It appears that there is a chipid0 and a chipid1 in Flash according to the Apollo datasheet https://cdn.sparkfun.com/assets/d/e/8/b … Z9Akgo.pdf that might be useful but I am not sure if it is possible to access them via the Arduino Core.

I’m going to guess you’d need to use the Ambiq SDK for that, but am not certain

Yes there is. See the HAL routine: ```
device_info_get(am_hal_mcuctrl_device_t *psDevice)


Or you can just read the relevant CPU registers directly:

uint32_t id0 = MCUCTRL->CHIPID0;
uint32_t id1 = MCUCTRL->CHIPID1;


I just checked the board on my bench and it returned 0x27883808 for CHIPID0 and 0x6b2abc82 for CHIPID1. They look like random numbers to me.

Thank you!
