For modern maintenance, this device requires the <b data-path-to-node=\"12\" data-index-in-node=\"101\">Xilinx ISE Design Suite (14.7)<\/b>. It is important to note that this part is not compatible with Vivado. If you are troubleshooting configuration issues, remember that the Virtex-4 utilizes a bitstream encryption (AES) and a unique configuration memory cells (CMVs) structure that differs from earlier Spartan or later 7-Series architectures.<\/p>\n<p data-path-to-node=\"12\"><a href=\"https:\/\/www.lxbchip.com\/ru\/contact-us\/\">\u0421\u0432\u044f\u0437\u0430\u0442\u044c\u0441\u044f \u0441 LXB Semicon<\/a>\u00a0for availability, pricing, and technical support.<\/p>","protected":false},"excerpt":{"rendered":"<p><strong>\u041f\u0440\u043e\u0438\u0437\u0432\u043e\u0434\u0438\u0442\u0435\u043b\u044c:<\/strong> AMD \/ Xilinx<br \/>\n<strong>\u041b\u043e\u0433\u0438\u0447\u0435\u0441\u043a\u0438\u0435 \u044f\u0447\u0435\u0439\u043a\u0438:<\/strong> 24,576<br \/>\n<strong>\u041b\u043e\u0433\u0438\u0447\u0435\u0441\u043a\u0438\u0435 \u0441\u0440\u0435\u0437\u044b:<\/strong> 2,400<br \/>\n<strong>\u0412\u0441\u0442\u0440\u043e\u0435\u043d\u043d\u0430\u044f \u043e\u043f\u0435\u0440\u0430\u0442\u0438\u0432\u043d\u0430\u044f \u043f\u0430\u043c\u044f\u0442\u044c (eRAM):<\/strong> 1 658 880 \u0431\u0438\u0442<br \/>\n<strong>\u0423\u043f\u0430\u043a\u043e\u0432\u043a\u0430:<\/strong> FFG668 (27\u00d727 \u043c\u043c)<br \/>\n<strong>\u0420\u0430\u0431\u043e\u0447\u0430\u044f \u0442\u0435\u043c\u043f\u0435\u0440\u0430\u0442\u0443\u0440\u0430:<\/strong> \u041e\u0442 40\u00b0C \u0434\u043e +100\u00b0C (\u043f\u0440\u043e\u043c\u044b\u0448\u043b\u0435\u043d\u043d\u044b\u0439)<\/p>","protected":false},"featured_media":96,"template":"","meta":{"_acf_changed":false,"jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"product_brand":[68],"product_cat":[21],"product_tag":[69],"class_list":{"0":"post-95","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-xilinx","7":"product_cat-xilinx","8":"product_tag-virtex-4-lx","10":"first","11":"instock","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"acf":[],"aioseo_notices":[],"jetpack_publicize_connections":[],"_links":{"self":[{"href":"https:\/\/www.lxbchip.com\/ru\/wp-json\/wp\/v2\/product\/95","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lxbchip.com\/ru\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.lxbchip.com\/ru\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lxbchip.com\/ru\/wp-json\/wp\/v2\/media\/96"}],"wp:attachment":[{"href":"https:\/\/www.lxbchip.com\/ru\/wp-json\/wp\/v2\/media?parent=95"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.lxbchip.com\/ru\/wp-json\/wp\/v2\/product_brand?post=95"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.lxbchip.com\/ru\/wp-json\/wp\/v2\/product_cat?post=95"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.lxbchip.com\/ru\/wp-json\/wp\/v2\/product_tag?post=95"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
