Category: I/O
Tool: ispLEVER Classic
Device: ispMACH 4000ZE, ispMACH 4000V/Z

It is possible to implement a 5V interface, but with the following limitations:

For input:
① The number of inputs should not exceed 64 per device
② Set the input buffer to "LVTTL" or "LVCMOS33_5V" (can be set with ispLEVER Classic)
(3) Set the Vcco of the I/O bank where the input signal is placed to 3.3V. This makes it impossible, for example, to place a pin that wants to output 1.8V and a pin that wants to input 5V in the same I/O bank.
④When inputting/outputting a 5V signal, 3.3V must be applied to Vcco (it does not support hot swapping).

For output:
①5V output is not possible. Must be set to open drain and have a 5V pull-up on the board outside the device (open drain can be set in ispLEVER Classic)
(2) It is necessary to observe the above conditions (1) to (4) as well as when entering
