With nearly 60,000 logic cells, this FPGA was designed as a logic-optimized workhorse, providing a massive amount of fabric for complex state machines, high-speed bus arbitration, and data-path management without the added cost or power overhead of the embedded PowerPC cores found in the FX series.<\/p>\n<p data-path-to-node=\"4\">Utilizing the <b data-path-to-node=\"4\" data-index-in-node=\"14\">FFG668 package<\/b> (a 1.0mm pitch Flip-Chip BGA), the LX60 offers a high I\/O-to-logic ratio, making it an ideal component for medical imaging, telecommunications infrastructure, and high-end industrial control units.<\/p>\n<p data-path-to-node=\"5\"><span style=\"color: #003366;\">Core Technical Parameters<\/span><\/p>\n<ul data-path-to-node=\"6\">\n<li>\n<p data-path-to-node=\"6,0,0\"><b data-path-to-node=\"6,0,0\" data-index-in-node=\"0\">Logische Zellen:<\/b> 59,904<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"6,1,0\"><b data-path-to-node=\"6,1,0\" data-index-in-node=\"0\">CLB Array:<\/b> 64 x 96<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"6,2,0\"><b data-path-to-node=\"6,2,0\" data-index-in-node=\"0\">Total Block RAM:<\/b> 2,880 Kb (160 blocks)<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"6,3,0\"><b data-path-to-node=\"6,3,0\" data-index-in-node=\"0\">DSP48 Slices:<\/b> 64<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"6,4,0\"><b data-path-to-node=\"6,4,0\" data-index-in-node=\"0\">Maximale Benutzer-E\/A:<\/b> 448<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"6,5,0\"><b data-path-to-node=\"6,5,0\" data-index-in-node=\"0\">Paket:<\/b> FFG668 (27mm x 27mm, 1.0mm pitch, Lead-Free\/RoHS)<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"6,6,0\"><b data-path-to-node=\"6,6,0\" data-index-in-node=\"0\">Geschwindigkeitsstufe:<\/b> -10<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"6,7,0\"><b data-path-to-node=\"6,7,0\" data-index-in-node=\"0\">Betriebstemp:<\/b> Handels\u00fcblich (0\u00b0C bis +85\u00b0C)<\/p>\n<\/li>\n<\/ul>\n<p data-path-to-node=\"7\"><strong><span style=\"color: #003366;\">Engineering Design &amp; Integration Notes<\/span><\/strong><\/p>\n<h4 data-path-to-node=\"8\">1. Power Supply and Thermal Profile<\/h4>\n<p data-path-to-node=\"9\">The 90nm process of the Virtex-4 LX60 requires a 1.2V <span class=\"math-inline\" data-math=\"V_{CCINT}\" data-index-in-node=\"54\">$V_{CCINT}$<\/span> core voltage. Because of the density (nearly 60k logic cells), static power consumption (leakage) can be higher than modern 7-series parts. Ensure your thermal solution\u2014whether passive heatsinking or forced air\u2014is characterized for your specific toggle rates. Even at the -10 speed grade, localized &#8220;hot spots&#8221; on the die can occur during high-utilization logic switching.<\/p>\n<h4 data-path-to-node=\"10\">2. Signal Integrity and SelectIO<\/h4>\n<p data-path-to-node=\"11\">The 448 user I\/Os are organized into multiple banks supporting a wide array of standards (LVDS, SSTL, HSTL, etc.). When maintaining or repairing existing PCBs, ensure the <span class=\"math-inline\" data-math=\"V_{CCO}\" data-index-in-node=\"171\">$V_{CCO}$<\/span> rails match the banking rules in your original <code data-path-to-node=\"11\" data-index-in-node=\"226\">.ucf<\/code> oder <code data-path-to-node=\"11\" data-index-in-node=\"234\">.xdc<\/code> constraint files. The FFG668 flip-chip package is designed for low-inductance power delivery, but proper bypass capacitor placement near the BGA footprint remains critical for high-speed signal integrity.<\/p>\n<h4 data-path-to-node=\"12\">3. Software Environment (ISE vs. Vivado)<\/h4>\n<p data-path-to-node=\"13\">It is important to remember that the Virtex-4 family is <b data-path-to-node=\"13\" data-index-in-node=\"56\">not supported by Vivado<\/b>. You must use <b data-path-to-node=\"13\" data-index-in-node=\"94\">Xilinx ISE Design Suite (version 14.7)<\/b> for synthesis and bitstream generation. If you are retrieving an old project, ensure your timing constraints are updated to account for the -10 speed grade specific propagation delays (<span class=\"math-inline\" data-math=\"T_{ILO}\" data-index-in-node=\"318\">$T_{ILO}$<\/span>, <span class=\"math-inline\" data-math=\"T_{AS}\" data-index-in-node=\"327\">$T_{AS}$<\/span>, etc.).<\/p>\n<hr data-path-to-node=\"14\" \/>\n<p data-path-to-node=\"15\"><strong><span style=\"color: #003366;\">Comparison: Virtex-4 LX60 vs. LX40 (FFG668)<\/span><\/strong><\/p>\n<table data-path-to-node=\"16\">\n<thead>\n<tr>\n<td><strong>Merkmal<\/strong><\/td>\n<td><strong>XC4VLX60-10FFG668C<\/strong><\/td>\n<td><strong>XC4VLX40-10FFG668C<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"16,1,0,0\"><b data-path-to-node=\"16,1,0,0\" data-index-in-node=\"0\">Logische Zellen<\/b><\/span><\/td>\n<td><span data-path-to-node=\"16,1,1,0\"><b data-path-to-node=\"16,1,1,0\" data-index-in-node=\"0\">59,904<\/b><\/span><\/td>\n<td><span data-path-to-node=\"16,1,2,0\">41,472<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"16,2,0,0\"><b data-path-to-node=\"16,2,0,0\" data-index-in-node=\"0\">BRAM (Kb)<\/b><\/span><\/td>\n<td><span data-path-to-node=\"16,2,1,0\"><b data-path-to-node=\"16,2,1,0\" data-index-in-node=\"0\">2,880<\/b><\/span><\/td>\n<td><span data-path-to-node=\"16,2,2,0\">1,728<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"16,3,0,0\"><b data-path-to-node=\"16,3,0,0\" data-index-in-node=\"0\">Max User I\/O<\/b><\/span><\/td>\n<td><span data-path-to-node=\"16,3,1,0\">448<\/span><\/td>\n<td><span data-path-to-node=\"16,3,2,0\">448<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"16,4,0,0\"><b data-path-to-node=\"16,4,0,0\" data-index-in-node=\"0\">Footprint Compatibility<\/b><\/span><\/td>\n<td><span data-path-to-node=\"16,4,1,0\">Ja<\/span><\/td>\n<td><span data-path-to-node=\"16,4,2,0\">Ja<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<hr data-path-to-node=\"17\" \/>\n<p data-path-to-node=\"18\"><strong><span style=\"color: #003366;\">Hardware Engineer\u2019s FAQ<\/span><\/strong><\/p>\n<p data-path-to-node=\"19\"><b data-path-to-node=\"19\" data-index-in-node=\"0\">Can I use the XC4VLX60-10FFG668C as a replacement for the -10FF668 (Leaded) version?<\/b><\/p>\n<p data-path-to-node=\"19\">Yes, but with one caveat: the &#8220;G&#8221; in FFG668 indicates a Lead-Free package.
