2.2. MAX® 10 I/O Elements

The MAX® 10 I/O elements (IOEs) contain a bidirectional I/O buffer and five registers for registering input, output, output-enable signals, and complete embedded bidirectional single data rate (SDR) and double data rate (DDR) transfer.

The I/O buffers are grouped into groups of four I/O modules per I/O bank:

  • The MAX® 10 devices share the user I/O pins with the VREF, RUP, RDN, CLKPIN, PLLCLKOUT, configuration, and test pins.
  • Schmitt Trigger input buffer is available in all I/O buffers.
  • When the MAX® 10 device is blank or erased, the I/Os are tri-stated.

Each IOE contains one input register, two output registers, and two output-enable (OE) registers:

  • The two output registers and two OE registers are used for DDR applications.
  • You can use the input registers for fast setup times and output registers for fast clock-to-output times.
  • You can use the OE registers for fast clock-to-output enable times.

You can use the IOEs for input, output, or bidirectional data paths. The I/O pins support various single-ended and differential I/O standards.
