FAQ

What is the maximum operating frequency supported by XC4VLX80-10FF1148I?

The XC4VLX80-10FF1148I is rated for a -10 speed grade, guaranteeing a maximum system clock frequency of 500 MHz for critical timing paths. This rating applies to internal logic paths under worst-case voltage and temperature conditions, and assumes proper PCB layout, power delivery, and timing constraints during synthesis and place-and-route.

Does XC4VLX80-10FF1148I support JTAG boundary-scan testing?

Yes, XC4VLX80-10FF1148I includes IEEE 1149.1-compliant JTAG TAP controller for boundary-scan testing, configuration, and debug. The TDO, TDI, TCK, and TMS pins are dedicated and mapped to specific balls in the FF1148 package, enabling in-system verification of solder joints and interconnect integrity.

What configuration modes are supported by XC4VLX80-10FF1148I?

XC4VLX80-10FF1148I supports Master Serial, Slave Serial, Master SelectMAP, Slave SelectMAP, and JTAG configuration modes. Configuration bitstream can be loaded from PROM, processor, or boundary-scan chain depending on system architecture requirements and security policies.

Is XC4VLX80-10FF1148I qualified for extended temperature operation?

Yes, the "I" suffix in XC4VLX80-10FF1148I denotes Industrial temperature range (-40°C to +100°C case temperature). This qualification includes thermal cycling, high-temperature operating life, and parameter validation across the full range, making it suitable for deployed avionics and industrial control environments.

How many clock regions does XC4VLX80-10FF1148I contain?

XC4VLX80-10FF1148I contains eight clock regions, each served by one dedicated CMT with dual DCMs. These regions allow independent clock domain management, reducing skew and enabling localized clock gating for dynamic power optimization in large-scale designs.
