Frequently asked questions
What is the brown-out reset trip voltage for 24V industrial sensor supply designs?
Brown-out Detect/Reset and Power-On Reset are listed as integrated peripherals, but the explicit BOR trip voltage is not present in the available spec entries. For 24V industrial sensor supply domains where supply sag on long cable runs is a concern, confirm the BOR threshold from the NXP datasheet before finalising the design without an external supervisor.
Does the 105°C rating hold under full peripheral load in a sealed panel enclosure?
The spec lists -40°C to 105°C as the ambient (TA) rating. In a sealed enclosure at high ambient, dissipation from the 2.4–3.6V supply and active peripherals reduces the available thermal headroom. The 105°C rating is the limit, not the recommended operating point — thermal design for the specific enclosure should be validated against the actual dissipation budget, not assumed to be a free 20°C margin.
