ContributorHi kh12,
Since this question is idling for more than two weeks, it was closed. Sorry if it brings you troubles.
Regarding your questions, I have some more comments.
1- The 5M240ZT144I5N you mentioned has two I/O banks, and there are multiple voltages you can choose to supply to each Bank. Also, the total current of I/O banks is dependent on the User's usage of the I/O Pins, including I/O standards, Current Strength settings, the number of I/O used and so on. Therefore, no specific supply current for VCCIO.
2- In the "DC and Switching Characteristics for MAX® V Devices - MAX V Device Handbook, Section I, Chapter 3" documentation, "Table 3–1. Absolute Maximum Ratings for MAX V Devices" mentioned the Iout limitation for each I/O pins. Is this helpful for you to estimate the total I/O current?
3- Also, have you tried using EPE (Early Power Estimation) tool? You can download the EPE tool and tool UG of MAX V device from this page below. Enter the resource usage estimated and you can get an estimation of the Power consumption.
Best Regards,
Xiaoyan
