FAQ

What is the maximum supported transceiver line rate for XC5VLX85T-1FF1136C?

The XC5VLX85T-1FF1136C supports RocketIO GTP transceivers with a maximum line rate of 3.75 Gbps. This enables compliance with PCIe Gen1 (2.5 Gbps), SATA I/II (1.5/3.0 Gbps), and Serial RapidIO (1.25/2.5/3.125 Gbps) standards. The actual achievable rate depends on PCB layout quality, reference clock stability, and termination matching.

Does XC5VLX85T-1FF1136C support partial reconfiguration?

Yes, XC5VLX85T-1FF1136C supports partial reconfiguration through Xilinx ISE design tools and associated bitstream generation flow. This allows dynamic replacement of logic modules without resetting the entire device, enabling runtime adaptation in radar and protocol gateway applications where continuous operation is required.

What configuration modes are available for XC5VLX85T-1FF1136C?

XC5VLX85T-1FF1136C supports multiple configuration modes: Master SelectMAP (parallel), Slave SelectMAP (parallel), Serial (SPI PROM), and JTAG. Mode selection is controlled by the M0–M2 pins at power-up. JTAG is used for debugging and programming, while Master SelectMAP enables fast parallel loading from external memory.

What is the operating temperature range for XC5VLX85T-1FF1136C?

The XC5VLX85T-1FF1136C is rated for industrial temperature operation from –40°C to +100°C junction temperature. This range supports deployment in avionics, medical, and industrial environments where ambient temperatures exceed commercial limits. Thermal design must maintain junction temperature within specification using appropriate heatsinking and airflow.

How many I/O banks does XC5VLX85T-1FF1136C have, and what voltage standards do they support?

XC5VLX85T-1FF1136C features 16 independently powered I/O banks. Each bank supports selectable I/O standards including LVCMOS, LVTTL, SSTL, HSTL, and differential standards such as LVDS and RSDS. Voltage levels per bank range from 1.2 V to 3.3 V, enabling direct interfacing with mixed-voltage peripherals without level-shifting components.
