Hello,
on your product info page, the operating temperature range for the nrf81522 is indicated as -40..+105C, while on the datasheet the same value is -25..+75. nrf81524's datasheet indicates -40..+105, in line with the product info page.
Two questions arise:
-
where is the cause of the difference in the nrf51822 data?
-
is the nrf81524 100% functionally compatible with the nrf51822?
Thank you for your support.
Mat.
