FAQ

What is the operating temperature range for XC7K325T-L2FFG676E?

The XC7K325T-L2FFG676E is specified for commercial temperature operation from 0°C to +85°C ambient. Its thermal design supports junction temperatures up to +100°C under typical airflow and PCB copper pour conditions. The device includes an integrated XADC for real-time die temperature monitoring, and thermal shutdown triggers at 125°C junction temperature. This rating aligns with standard commercial-grade FPGA deployment environments.

Does XC7K325T-L2FFG676E support partial reconfiguration?

Yes, XC7K325T-L2FFG676E fully supports partial reconfiguration through Vivado Design Suite tools. This capability allows runtime swapping of logic modules without resetting the entire device or halting system operation. The feature relies on dedicated configuration logic and frame-based bitstream addressing, enabling dynamic adaptation in radar waveform generation or protocol stack updates. Partial reconfiguration requires specific HDL partitioning and checkpointing workflows validated in the XC7K325T-L2FFG676E silicon.

What transceiver protocols are natively supported by XC7K325T-L2FFG676E?

XC7K325T-L2FFG676E transceivers natively support PCIe Gen2 (5.0 GT/s), SATA 3Gbps, CPRI (up to Option 10), SRIO 2.1, and 10GBASE-R. Protocol compliance is implemented via hard IP blocks and verified reference designs provided by AMD. Each transceiver quad includes dedicated TX/RX phase alignment circuitry and PRBS pattern generators for link integrity testing. No external retimers or protocol converters are needed for these standards.

Can XC7K325T-L2FFG676E be configured via JTAG only, without external flash?

Yes, XC7K325T-L2FFG676E supports JTAG-only configuration for prototyping and debugging. In this mode, the bitstream is loaded directly from a host PC or debugger without requiring external SPI flash memory. However, JTAG configuration is volatile and does not persist after power loss. For production systems requiring autonomous startup, Master SPI mode with external flash remains the standard method. Both methods use identical bitstream files generated by Vivado.

What is the maximum DDR3 memory interface speed supported by XC7K325T-L2FFG676E?

XC7K325T-L2FFG676E supports DDR3 SDRAM interfaces up to 800 MHz data rate (1600 MT/s), corresponding to CL=6 timing at 1.5 V VDDQ. This is achieved using the device's dedicated memory interface logic with calibrated delay elements and write-leveling support. The controller supports x8/x16/x32 data widths and includes built-in ECC for single-bit error correction. Verified reference designs confirm stable operation with Micron MT41J256M16HA-125 and similar JEDEC-compliant components.
