Footprint Efficiency vs. I\/O Access<\/h4>\n<p data-path-to-node=\"10\">The SFG363 package is roughly 60% smaller by area than the FFG668 variant. However, this comes at the cost of &#8220;bonded-out&#8221; I\/O. With 240 pins available, ensure your pin-assignment (.ucf) does not exceed the physical constraints of this package. If you are migrating a design from a larger Virtex-4 device, you will likely need to re-evaluate your I\/O bank assignments.<\/p>\n<h4 data-path-to-node=\"11\">2. Configuration &amp; Bitstream<\/h4>\n<p data-path-to-node=\"12\">This device supports standard configuration modes including Slave Serial, Master Serial, SelectMAP, and JTAG. Given the 24k logic cell density, bitstream sizes are manageable for standard PROM or Flash configurations. Note that the Virtex-4 requires a <b data-path-to-node=\"12\" data-index-in-node=\"252\">1.2V <span class=\"math-inline\" data-math=\"V_{CCINT}\" data-index-in-node=\"257\">$V_{CCINT}$<\/span><\/b> rail; ensure your power delivery network (PDN) is characterized for the specific switching transients of the LX fabric.<\/p>\n<h4 data-path-to-node=\"13\">3. Legacy Tooling (ISE 14.7)<\/h4>\n<p data-path-to-node=\"14\">As a reminder for teams maintaining older platforms, the XC4VLX25 is <b data-path-to-node=\"14\" data-index-in-node=\"69\">not supported by Xilinx Vivado<\/b>. You must use the <b data-path-to-node=\"14\" data-index-in-node=\"118\">ISE Design Suite<\/b>. We recommend using the final 14.7 release to ensure all timing models and silicon-specific errata are correctly addressed during synthesis and place-and-route.<\/p>\n<hr data-path-to-node=\"15\" \/>\n<p data-path-to-node=\"16\"><strong><span style=\"color: #003366;\">Comparison: XC4VLX25 SFG363 vs. FFG668<\/span><\/strong><\/p>\n<table data-path-to-node=\"17\">\n<thead>\n<tr>\n<td><strong>T\u00ednh n\u0103ng<\/strong><\/td>\n<td><strong>XC4VLX25-10SFG363C<\/strong><\/td>\n<td><strong>XC4VLX25-10FFG668C<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"17,1,0,0\"><b data-path-to-node=\"17,1,0,0\" data-index-in-node=\"0\">Physical Dimensions<\/b><\/span><\/td>\n<td><span data-path-to-node=\"17,1,1,0\"><b data-path-to-node=\"17,1,1,0\" data-index-in-node=\"0\">17mm x 17mm<\/b><\/span><\/td>\n<td><span data-path-to-node=\"17,1,2,0\">27mm x 27mm<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"17,2,0,0\"><b data-path-to-node=\"17,2,0,0\" data-index-in-node=\"0\">Ball Pitch<\/b><\/span><\/td>\n<td><span data-path-to-node=\"17,2,1,0\"><b data-path-to-node=\"17,2,1,0\" data-index-in-node=\"0\">0.8mm<\/b><\/span><\/td>\n<td><span data-path-to-node=\"17,2,2,0\">1.0mm<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"17,3,0,0\"><b data-path-to-node=\"17,3,0,0\" data-index-in-node=\"0\">Available User I\/O<\/b><\/span><\/td>\n<td><span data-path-to-node=\"17,3,1,0\">240<\/span><\/td>\n<td><span data-path-to-node=\"17,3,2,0\">448<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"17,4,0,0\"><b data-path-to-node=\"17,4,0,0\" data-index-in-node=\"0\">Logic\/BRAM\/DSP<\/b><\/span><\/td>\n<td><span data-path-to-node=\"17,4,1,0\">Identical<\/span><\/td>\n<td><span data-path-to-node=\"17,4,2,0\">Identical<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<hr data-path-to-node=\"18\" \/>\n<p data-path-to-node=\"19\"><strong><span style=\"color: #003366;\">Engineering FAQ<\/span><\/strong><\/p>\n<p data-path-to-node=\"20\"><b data-path-to-node=\"20\" data-index-in-node=\"0\">Is the SFG363 package lead-free?<\/b><\/p>\n<p data-path-to-node=\"20\">Yes, the &#8220;G&#8221; in the SFG363 suffix indicates a Lead-Free (RoHS compliant) package.
