Frequently Asked Questions
What is the main difference between XC3064-100 and XC3064-70?
The speed grade determines maximum operating frequency and timing parameters. The -70 grade offers 70 MHz toggle rate with slower logic delays, while the -100 grade provides 100 MHz performance with faster switching characteristics.
Can I replace XC3064-100PQ160C with XC3064A?
The XC3000A family offers enhanced features and better performance. While bitstreams are upward compatible from XC3000 to XC3000A, Xilinx recommends using XC3000A for new designs. However, the XC3064-100PQ160C remains suitable for legacy design support.
How many logic gates can I implement?
While the nominal gate count ranges from 3,000 to 6,000 gates, actual utilization depends on design complexity, routing efficiency, and CLB usage patterns. Complex designs with intensive routing may achieve lower utilization than simple, regular structures.
What programming modes does this FPGA support?
The XC3064 supports Master Serial, Slave Serial, Peripheral, and Boundary Scan (JTAG) configuration modes, providing flexibility for various system architectures.
