Hi,I will couple a led driver Cyclone IV DE2i150 but I need Cyclone IV DE2i150 GPIO output impedance. Could you help me? Thank you.
The output behavior is specified by guaranteed logic levels for a specific drive strength, which should suffice for most applications. A full specification including minimal, maximal and typical output I/V curves is given in the device Ibis files. Maximum current ratings for pins and pin groups must be observed additionally.
