FAQ

What is the maximum supported transceiver data rate for XC7K355T-1FFG901I?

The XC7K355T-1FFG901I supports GTPE2 transceivers with a maximum data rate of 13.1 Gb/s per lane. This enables compliance with 10GBASE-R, CPRI Option 3, and Interlaken standards. The actual achievable rate depends on PCB layout quality, reference clock jitter, and termination matching per UG476 v1.12.

Does XC7K355T-1FFG901I support partial reconfiguration?

Yes, XC7K355T-1FFG901I fully supports partial reconfiguration through Vivado Design Suite. This allows runtime swapping of logic modules without resetting the entire device, enabling dynamic function updates in radar and test equipment applications where continuous operation is required.

What configuration modes are available for XC7K355T-1FFG901I?

XC7K355T-1FFG901I supports Master SPI, Slave SelectMAP, JTAG, and BPI configuration modes. Mode selection is controlled by M0–M2 pins at power-up. SPI mode is most common for compact, low-pin-count boot solutions, while SelectMAP suits high-speed parallel programming.

Is XC7K355T-1FFG901I qualified for industrial temperature operation?

Yes, the "I" suffix in XC7K355T-1FFG901I denotes industrial temperature grade, guaranteeing reliable operation from –40°C to +100°C junction temperature. Thermal design must maintain case temperature within this range using appropriate heatsinking and airflow per Xilinx DS182 v2.7.

What security features does XC7K355T-1FFG901I provide for bitstream protection?

XC7K355T-1FFG901I includes AES-256 bitstream encryption and HMAC-SHA256 authentication. These features prevent unauthorized access to FPGA configuration data and ensure only validated bitstreams execute, meeting DO-254 and IEC 62443 requirements for secure embedded systems.
