The XPIO are grouped into 54-pin banks with supporting resources for both high-performance and low-speed interfaces. Each XPIO can use the XPHY to align, serialize, and de-serialize a data stream. Each XPIO has I/O interconnect logic (IOL) resources to support low-speed SDR and DDR interfaces and coarse data alignment resources. The XPIO input and output buffers support a wide range of single-ended and differential I/O standards along with resources to support a high level of signal quality.
- 1.0V, 1.2V, 1.35V, and 1.5V bank voltage standards
