Hi Wang-san,
Please let me ask one more question.
QJ Wang said:Hi Sasaki,
Normally for device with separate power supplies for core and IO, the core is powered first, then IO. Hercules MCUs have built-in VMON module which handles the power sequence for Core and IO, so there is no requirement of power sequence for Vcc and Vccio. The VMON doesn't monitor Vccad, I recommend Vcc and Vccio first, then Vccad.
If Vccad is supplied before Vcc and Vccio, will it cause a fault such as latch-up?
Best regards,
Sasaki
