FAQ

What is the maximum operating temperature for XC4VLX40-11FF1148I?

The XC4VLX40-11FF1148I is rated for industrial temperature range: –40°C to +100°C case temperature. This rating applies to the I-grade version indicated by the final 'I' in the part number. Thermal derating begins above 85°C ambient, and junction temperature must remain below 125°C under all operating conditions. The FF1148 package's θ_JA of 5.9°C/W defines the required board-level thermal design margin.

Does XC4VLX40-11FF1148I support JTAG boundary-scan testing?

Yes, XC4VLX40-11FF1148I fully complies with IEEE 1149.1 (JTAG) standard. It implements TAP controller, instruction register, and boundary-scan register supporting INTEST, SAMPLE/PRELOAD, and EXTEST instructions. All 720 user I/Os are accessible via boundary-scan cells, enabling PCB interconnect verification prior to configuration.

Can XC4VLX40-11FF1148I be configured via SPI flash memory?

Yes, XC4VLX40-11FF1148I supports master SPI configuration mode using industry-standard serial NOR flash devices. In this mode, the FPGA actively clocks the flash and reads the bitstream upon power-up or PROGRAM_B assertion. Supported densities range from 2 to 32 Mbits, and the device auto-detects flash manufacturer ID and command set.

What configuration modes does XC4VLX40-11FF1148I support?

XC4VLX40-11FF1148I supports six configuration modes: Master SelectMAP, Slave SelectMAP, Master Serial (SPI), Slave Serial, JTAG, and Boundary Scan. Mode selection is controlled by the MODE pins (M[2:0]) at power-up. Each mode defines distinct pin assignments for data, control, and clock signals during bitstream loading.

Is partial reconfiguration supported on XC4VLX40-11FF1148I?

Yes, XC4VLX40-11FF1148I supports hardware-accelerated partial reconfiguration through its ICAP (Internal Configuration Access Port) and frame-based bitstream addressing. This allows dynamic replacement of logic modules without resetting the entire device. Xilinx ISE 14.7 tools provide certified flow for partitioning, place-and-route, and bitstream generation targeting XC4VLX40-11FF1148I.
