I/O Tile Overview - I/O Tile Overview - UG861

The AMD Spartan™ UltraScale+™ devices provide high-performance (HP), high-density (HD), and XP5IO offerings. Although HP I/O and HD I/O resources are similar to other UltraScale+ device resources, the Spartan UltraScale+ family has subtle differences. These differences, along with the unique XP5IO warrant this unique SelectIO™ user guide specific to the Spartan UltraScale+ family .

• The HP I/O banks are designed to meet the performance requirements of high-speed memory and other chip-to-chip interfaces with voltages between 1.0V and 1.8V.
• The HD I/O banks are designed to support low-speed interfaces with voltages between 1.2V and 3.3V.
• The XP5IO banks are designed to enhance I/O support for LPDDR5 interfaces as well as improving performance on high-speed interfaces like MIPI D-PHY. XP5IO are powered with a voltage between 1.0V and 1.5V but can be used to interface with lower voltage LVSTL interfaces.

Spartan UltraScale+ devices contain different combinations of HP, HD, and XP5IO I/O banks, though not all types of banks or pins within a bank are supported in all devices. The UltraScale Architecture and Product Data Sheet: Overview (DS890) documents the available number of each type of bank for all devices.

The Spartan UltraScale+ family has high-performance I/O banks (HP and XP5IO) with MIPI D-PHY capabilities and the corresponding logic resources. They also have high-density I/Os (HD I/Os) with corresponding logic resources.
