5V tolerance for the MCU module I/O ports?
2011-05-17 03:08 AM
Hi,
I am considering to use uPSD3354DV-40U6 and was looking at the voltage tolerance of the I/O ports in the datasheet. On page 13, only the Port 3 & 4 are 5V tolerant. But on page 207, the Vih is 5.5V max. for Ports 0,1,2,3,4, XTAL1, RESET. I need to find out whether Port 1 is 5V tolerant, since there is some conflicting statements in the datasheet. Can anyone help confirm the actual ports which are 5V tolerant? Thanks in advance. Rgds, Nick2011-05-17 03:08 AM
Port 1 is NOT 5V tolerant. Page 207 in the data sheet needs to be updated appropriately.
