FAQ
What is the maximum operating frequency of the XC4VSX25-10FF668C?
The XC4VSX25-10FF668C carries the -10 speed grade, guaranteeing timing closure for critical paths up to 500 MHz under industrial temperature conditions. This rating applies to internal logic paths and is validated using Xilinx ISE timing analysis tools with worst-case voltage and temperature corners.
Does the XC4VSX25-10FF668C support partial reconfiguration?
Yes, the XC4VSX25-10FF668C supports hardware-accelerated partial reconfiguration through Xilinx ISE design tools. This capability allows dynamic swapping of logic modules-such as filter banks or protocol engines-without resetting the entire device or interrupting active I/O channels.
What configuration modes does the XC4VSX25-10FF668C support?
The XC4VSX25-10FF668C supports Master Serial, Slave Serial, JTAG, and Boundary Scan configuration modes. Mode selection is controlled by M0–M2 pins at power-up, and configuration bitstreams can be loaded from SPI PROM, microprocessor, or JTAG debugger.
Is the XC4VSX25-10FF668C RoHS compliant?
Yes, the XC4VSX25-10FF668C is RoHS-6 compliant (lead-free, mercury-free, cadmium-free, hexavalent chromium-free, PBB-free, PBDE-free) and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements for surface-mount assembly.
