FAQ

What is the maximum supported DDR3 data rate for XC7A25T-L2CSG325E?

The XC7A25T-L2CSG325E supports DDR3/DDR3L memory interfaces up to 800 MHz data rate (1600 MT/s) using its dual Memory Interface Generator (MIG) controllers. This capability is validated in Xilinx UG473 and applies directly to the XC7A25T-L2CSG325E with appropriate board layout and termination. The -2 speed grade ensures timing closure for this rate across industrial temperature ranges.

Does XC7A25T-L2CSG325E include a hard PCIe controller?

Yes, XC7A25T-L2CSG325E integrates a hardened PCI Express Gen2 x4 endpoint block compliant with the PCIe Base Specification v2.1. This dedicated IP eliminates the need for soft-core implementations, reduces logic utilization, and guarantees deterministic latency. The controller supports both root port and endpoint configurations and is accessible through Xilinx's PCIe IP core in Vivado.

What I/O standards are supported by XC7A25T-L2CSG325E?

XC7A25T-L2CSG325E supports LVDS, SSTL, HSTL, TMDS, and differential signaling standards up to 1.25 Gbps per differential pair via its SelectIO technology. Each of the 10 I/O banks can be independently configured for voltage levels from 1.2 V to 3.3 V. These capabilities are documented in Xilinx DS182 and apply specifically to the XC7A25T-L2CSG325E in CSG325 packaging.

Is partial reconfiguration supported on XC7A25T-L2CSG325E?

Yes, XC7A25T-L2CSG325E supports partial reconfiguration as defined in Xilinx UG909. This allows dynamic updating of specific logic regions without resetting the entire device or halting system operation. The feature requires Vivado Design Suite 2014.4 or later and is enabled by the underlying Kintex-7 architecture used in XC7A25T-L2CSG325E.

What is the operating temperature range for XC7A25T-L2CSG325E?

XC7A25T-L2CSG325E is rated for industrial temperature range: –40°C to +100°C junction temperature. This specification is confirmed in the official Xilinx (now AMD) DS182 datasheet for the Kintex-7 family and applies to the XC7A25T-L2CSG325E with -2 speed grade and CSG325 packaging. Thermal design must ensure proper heatsinking to maintain Tj within limits.
