10 years agoPower On VCCIO before VCCINT
HI,
What will happen to IO pins voltage if the VCCIO supply is powered ON before VCCINT supply during initial board Power-UP? Take note that during initial power-UP the FPGA is in unknown state. Does it cause some voltage glitch of several milliseconds across I/O pins during initial power up? Regards,
