5.7. I/O Element Structure in Cyclone® V Devices

The I/O elements (IOEs) in Cyclone® V devices contain a bidirectional I/O buffer and I/O registers to support a complete embedded bidirectional single data rate (SDR) or double data rate (DDR) transfer.

The IOEs are located in I/O blocks around the periphery of the Cyclone® V device.

The Cyclone® V SE, SX, and ST devices also have I/O elements for the HPS.
