First time using the ICE5LP4K and trying to verify that my power on sequence is sufficient. I attached the sequence stated in data sheet, and my design snippets for retaliative sections. I see a lot of public design references do not have much in controlling this power up voltage levels, is it not really important or is there something I am missing ? I did use a voltage supervisor ( MIC803-26D4VC3 ) to make the 1V2 come up before the 3V3 by 1ms, but there isn't really anything controlling SPI_VCCIO, VPP_2V5, in that order, after VCC and before VCCIO0. This is a small board, and if it is needed can it be done with just RC circuit or can I just ignore it ? Small board and I am running out of room.
