TMS570LS3137： supply VCCAD before supplying VCC and VCCIO

Part Number:TMS570LS3137

Hi Wang-san,

Please let me ask one more question.

[quote user="QJ Wang"]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
