Part Number:MSP430F5528
Hello,
With many MSP430F5528 we face some reset issue: the MCU correctly gets out of the reset when power supply is active while the USB automate stays in a state which do not permit any access.
The USB 5V is linked to the VUSB pin + used to supply the battery. The battery supplies a 3.0V regulator which supplies the MSP430F5528 DVCC and an external reset (MCP121T-240B).
If after a while I manually trig a reset, everything is ok. The issue is that the customer can not access the reset pin inside the box.
Do you any idea?
Best regards
Mich
