FAQ

What is the maximum supported I/O standard voltage for XC5VLX85-2FFG1153I?

The XC5VLX85-2FFG1153I supports I/O standards ranging from 1.2 V to 3.3 V across its 12 I/O banks, with each bank independently configurable for voltage levels including SSTL-18, HSTL-I, LVCMOS25, and LVDS. Bank-specific VCCO must match the selected standard's nominal voltage, and all banks share a common VCCAUX supply of 2.5 V.

Does XC5VLX85-2FFG1153I include built-in configuration memory?

No, the XC5VLX85-2FFG1153I does not include on-chip non-volatile configuration memory. It relies on external serial PROM (e.g., XCFxxP series) or microcontroller-driven parallel configuration. Configuration is loaded on power-up via Master SPI, Slave SelectMAP, or JTAG modes, and the bitstream is stored in SRAM-based CLBs.

Can XC5VLX85-2FFG1153I operate in a 0°C to +70°C environment?

Yes, the XC5VLX85-2FFG1153I is rated for industrial temperature range (-40°C to +100°C), so it fully supports operation at 0°C to +70°C. The -2 speed grade guarantees timing performance across this entire range without derating, making it suitable for commercial and industrial deployments where ambient conditions fall within that span.

What JTAG chain compatibility does XC5VLX85-2FFG1153I support?

The XC5VLX85-2FFG1153I complies with IEEE 1149.1 (JTAG) and supports daisy-chained JTAG configurations with other Xilinx devices. Its TCK, TMS, TDI, and TDO pins allow boundary-scan testing, in-system programming, and debug access using Xilinx iMPACT or Vivado Hardware Manager tools.

Is partial reconfiguration supported on XC5VLX85-2FFG1153I?

Yes, the XC5VLX85-2FFG1153I supports partial reconfiguration through the Platform Designer flow in Xilinx ISE Design Suite. This allows dynamic swapping of logic modules-such as filter coefficients or protocol engines-without resetting the entire device or halting system operation, provided the reconfigurable partitions are properly constrained and verified.
