一、Xilinx芯片规则

型号： xc7k160t-2ffg676

型号命名规则：

1. xc7k代表Xilinx的Kintex®-7系列
2. 160t代表system gates或logic cells的数目，即160,000个logic cells
3. -2代表速度等级
4. Ffg     FFG是封装方式（Pb-free flip-chip BGA）
5. 676是引脚数目，但用户的I/O即可用管教约为400个，如下图所示：

6）Kintex®-7系列芯片的速度等级和性能区别：

Kintex®-7 FPGAs are available in -3, -2, -1, -1L, and -2L speed grades, with -3 having the highest performance. The -2L devices are screened for lower maximum static power and can operate at lower core voltages for lower dynamic power than the -2 devices. The -2L industrial (I) temperature devices operate only at VCCINT = 0.95V. The -2L extended (E) temperature devices can operate at either VCCINT = 0.9V or 1.0V. The -2LE devices when operated at VCCINT = 1.0V, and the -2LI devices when operated at VCCINT = 0.95V, have the same speed specifications as the -2 speed grade, except where noted. When the -2LE devices are operated at VCCINT = 0.9V, the speed specifications, static power, and dynamic power are reduced. The -1L military (M) temperature devices have the same speed specifications as the -1 military temperature devices and are screened for lower maximum static power.

Sample Ordering Code and Available Options for Cyclone V SX Devices

The SEU internal scrubbing feature is available for Cyclone V E, GX, SE, and SX devices with the "SC" suffix in the part number. For device availability and ordering, contact your local Intel sales representatives. Cyclone V SE and SX low-power devices (L power option) offer 30% static power reduction for devices with 25K LE and 40K LE, and 20% static power reduction for devices with 85K LE and 110K LE.
