FAQ

What is the maximum supported I/O standard voltage for XC5VLX155-1FF1153C?

The XC5VLX155-1FF1153C supports I/O bank voltages from 1.2 V to 3.3 V per bank, enabling direct interfacing with LVCMOS, LVTTL, SSTL-18/25, HSTL-I/II, and differential standards including LVDS and RSDS. Each of the 24 I/O banks is independently configurable, allowing mixed-voltage operation on a single device. This flexibility is essential for bridging legacy and modern peripherals in systems like avionics data concentrators.

Does XC5VLX155-1FF1153C include hard IP for PCI Express?

Yes, XC5VLX155-1FF1153C integrates a hard PCIe Endpoint block compliant with PCI Express Base Specification v1.1, supporting Gen1 x1, x2, and x4 configurations. This dedicated block operates independently of FPGA fabric resources, preserving logic cells for application-specific functions. The PCIe interface is accessible through dedicated GT transceivers and configuration registers mapped into the device's address space.

What configuration modes does XC5VLX155-1FF1153C support?

XC5VLX155-1FF1153C supports Master SelectMAP, Slave SelectMAP, JTAG, and Serial Peripheral Interface (SPI) configuration modes. Master SelectMAP enables autonomous boot from external PROM, while JTAG is used for boundary-scan testing and in-system programming. Configuration bitstreams can be loaded via parallel or serial interfaces, with fallback mechanisms implemented in hardware for field reliability.

How many RocketIO GTP transceivers are available on XC5VLX155-1FF1153C?

XC5VLX155-1FF1153C includes 24 RocketIO GTP transceivers, each capable of serial data rates from 100 Mb/s to 3.75 Gb/s. These transceivers support protocols including SATA, Serial RapidIO, and custom high-speed links. All 24 lanes are fully operational in the FF1153 package, with dedicated reference clock inputs and programmable equalization settings per channel.

Is partial reconfiguration supported on XC5VLX155-1FF1153C?

Yes, XC5VLX155-1FF1153C supports partial reconfiguration through its ICAP (Internal Configuration Access Port) and dedicated frame-based bitstream loading mechanism. This allows dynamic swapping of functional modules-such as filter banks or protocol engines-without resetting the entire device. Partial reconfiguration requires specific toolflow support in Xilinx ISE Design Suite 13.x or later and compatible floorplanning constraints.
