XAPP457 - Powering and Configuring Spartan-3 Generation FPGAs in Compliant PCI Applications (PDF)
View Document Details
The PCI™ Local Bus Specification defines a number of power and reset requirements. When considered in an FPGA implementation, these create several challenges that must be addressed for long term reliability and broad interoperability. This application note applies to compliant PCI applications using Spartan™-3 Generation FPGAs, and is relevant to other Xilinx FPGA families, as well as related PCI applications.

XAPP389 - 为 CoolRunner-II CPLD 供电(中文版) (PDF)
View Document Details
通常,施加到板上的电源电压比 CoolRunner™-II CPLD 所需的 1.8V VCCINT 的额定电压要高(或低)。 这些情况下,电源 IC 一般用于执行电源电压所需的 DC/DC 转换。 给这些器件,即稳压器,输入一个未经稳压的电压,然后,器件会输出一个独立于输入电压变化或输出电流波动的稳定电压。 稳压器有很多种不同的类型。 本应用指南对稳压器的每种类型都进行了说明,并给出了一些典型电路来重点说明现有的商用稳压器。 Was this document helpful? Yes | No

WP298 - Power Consumption at 40 and 45 nm (PDF)
View Document Details
At 40 and 45 nm process nodes, power has become the primary factor for FPGA selection. Spartan®-6 and Virtex®-6 FPGAs offer lower power, simpler power systems and PCB complexity, better reliability, and lower system cost. This white paper details how Xilinx designed for this new reality in Spartan-6 (45 nm) and Virtex-6 (40 nm) FPGA families, achieving dramatic power reductions over previous generation devices.
