Spartan-7 FPGAs Data Sheet: DC and AC Switching Characteristics DS189 (v1.9) March 13, 2019 Product Specification Introduction Spartan®-7 FPGAs are available in -2, -1, and -1L speed grades, with -2 having the highest performance. The Spartan-7 FPGAs predominantly operate at a 1.0V core voltage. The -1L devices are screened for lower maximum static power and can operate at lower core voltages for lower dynamic power than the -1 devices. The -1L devices operate only at VCCINT = VCCBRAM = 0.95V and have the same speed specifications as the -1 speed grade. Spartan-7 FPGA DC and AC characteristics are specified in commercial (C), industrial (I), and expanded (Q) temperature ranges. Except the operating temperature range or unless otherwise noted, all the DC and AC electrical parameters are the same for a particular speed grade (that is, the timing characteristics of a -1Q expanded speed grade device are the same as for a -1C commercial speed grade device). However, only selected speed grades and/or devices are available in each temperature range. For example, the -1L speed grade is only available in the industrial (I) temperature range. All supply voltage and junction temperature specifications are representative of worst-case conditions. The parameters included are common to popular designs and typical applications. Available device and package combinations can be found in: • 7 Series FPGAs Overview (DS180) [Ref 1] • XA Spartan-7 Automotive FPGA Data Sheet: Overview (DS171) [Ref 2] This Spartan-7 FPGA data sheet, part of an overall set of documentation on the 7 series FPGAs, is available on the Xilinx website at www.xilinx.com/documentation.

Typical values are specified at nominal voltage, 85°C junction temperature (Tj) with single-ended SelectIO™ resources. Typical values are for blank configured devices with no output current loads, no active input pull-up resistors, all I/O pins are 3-state and floating. Use the Xilinx Power Estimator spreadsheet tool [Ref 6] to estimate static power consumption for conditions other than those specified. Power-On/Off Power Supply Sequencing The recommended power-on sequence is VCCINT, V CCBRAM, VCCAUX, and VCCO to achieve minimum current draw and ensure that the I/Os are 3-stated at power-on. The recommended power-off sequence is the reverse of the power-on sequence. If VCCINT and VCCBRAM have the same recommended voltage levels then both can be powered by the same supply and ramped simultaneously. If V CCAUX and VCCO have the same recommended voltage levels then both can be powered by the same supply and ramped simultaneously. For V CCO voltages of 3.3V in HR I/O banks and configuration bank 0 the following conditions apply. • The voltage difference between VCCO and V CCAUX must not exceed 2.625V for longer than TVCCO2VCCAUX for each power-on/off cycle to maintain device reliability levels. • The T VCCO2VCCAUX time can be allocated in any percentage between the power-on and power-off ramps. There is no recommended sequence for supplies not discussed in this section.

If the current minimums shown in Table 6 are met, the device powers on after all four supplies have passed through their power-on reset threshold voltages. The FPGA must not be configured until after VCCINT is applied. Once initialized and configured, use the Xilinx Power Estimator spreadsheet tool [Ref 6] to estimate current drain on these supplies.

DS189 (v1.9) March 13, 2019 Product Specification www.xilinx.com Send Feedback 11 Spartan-7 FPGAs Data Sheet: DC and AC Switching Characteristics AC Switching Characteristics All values represented in this data sheet are based on the speed specifications from the Vivado® Design Suite as outlined in Table 12. Table 12: Speed Specification Version By Device 2018.2.1 Device 1.23 XC7S6, XC7S15, XC7S25, XC7S50, XC7S75, XC7S100 1.16 XA7S6, XA7S15, XA7S25, XA7S50, XA7S75, XA7S100 Switching characteristics are specified on a per-speed-grade basis and can be designated as Advance, Preliminary, or Production. Each designation is defined as follows. Advance Product Specification These specifications are based on simulations only and are typically available soon after device design specifications are frozen. Although speed grades with this designation are considered relatively stable and conservative, some under-reporting might still occur. Preliminary Product Specification These specifications are based on complete ES (engineering sample) silicon characterization. Devices and speed grades with this designation are intended to give a better indication of the expected performance of production silicon. The probability of under-reporting delays is greatly reduced as compared to Advance data. Production Product Specification These specifications are released once enough production silicon of a particular device family member has been characterized to provide full correlation between specifications and devices over numerous production lots. There is no under-reporting of delays, and customers receive formal notification of any subsequent changes. Typically, the slowest speed grades transition to Production before faster speed grades. Testing of AC Switching Characteristics Internal timing parameters are derived from measuring internal test patterns. All AC switching characteristics are representative of worst-case supply voltage and junction temperature conditions. For more specific, more precise, and worst-case guaranteed data, use the values reported by the static timing analyzer and back-annotate to the simulation net list. Unless otherwise noted, values apply to all Spartan-7 FPGAs.

Production Silicon and Software Status In some cases, a particular family member (and speed grade) is released to production before a speed specification is released with the correct label (Advance, Preliminary, Production). Any labeling discrepancies are corrected in subsequent speed specification releases. Table 14 lists the production released Spartan-7 device, speed grade, and the minimum corresponding supported speed specification version and software revisions. The software and speed specifications listed are the minimum releases required for production. All subsequent releases of software and speed specifications are valid.

IOB Pad Input/Output/3-State Table 17 summarizes the values of standard-specific data input delay adjustments, output delays terminating at pads (based on standard) and 3-state delays. • TIOPI is described as the delay from IOB pad through the input buffer to the I-pin of an IOB pad. The delay varies depending on the capability of the SelectIO input buffer. • TIOOP is described as the delay from the O pin to the IOB pad through the output buffer of an IOB pad. The delay varies depending on the capability of the SelectIO output buffer. • TIOTP is described as the delay from the T pin to the IOB pad through the output buffer of an IOB pad, when 3-state is disabled. The delay varies depending on the SelectIO capability of the output buffer. In HR I/O banks, the IN_TERM termination turn-on time is always faster than TIOTP when the INTERMDISABLE pin is used.

The most accurate prediction of propagation delay in any given application can be obtained through IBIS simulation, using this method: 1. Simulate the output driver of choice into the generalized test setup using values from Table 20. 2. Record the time to V MEAS. 3. Simulate the output driver of choice into the actual PCB trace and load using the appropriate IBIS model or capacitance value to represent the load. 4. Record the time to V MEAS. 5. Compare the results of step 2 and step 4. The increase or decrease in delay yields the actual propagation delay of the PCB trace.

These parameters represent the worst-case duty cycle distortion observable at the I/O flip flops. For all I/O standards, IBIS can be used to calculate any additional duty cycle distortion that might be caused by asymmetrical rise/fall times. The TCKSKEW value represents the worst-case clock-tree skew observable between sequential I/O elements. Significantly less clock-tree skew exists for I/O registers that are close to each other and fed by the same or adjacent clock-tree branches. Use the Xilinx timing analysis tools to evaluate clock skew specific to your application.

XC7S15-2CSGA225C
物料型号:Xilinx Spartan-7 FPGAs

器件简介: Spartan-7 FPGA系列提供-2、-1和-1L三种速度等级,其中-2性能最高。这些FPGA主要在1.0V的核心电压下运行。-1L设备针对较低的最大静态功率进行了筛选,可以在较低的核心电压下运行,与-1设备相比具有较低的动态功率。-1L设备仅在VCCINT = VCCBRAM = 0.95V下运行,并与-1速度等级设备具有相同的速度规格。

引脚分配:文档中未提供具体的引脚分配信息,通常这可以在FPGA的数据手册或用户指南中找到。

参数特性: - 供电电压:VCCINT(内部供电电压)、VCCAUX(辅助供电电压)、VCCBRAM(块RAM存储器供电电压)、VCCO(高阻抗I/O银行输出驱动器供电电压)、VREF(输入参考电压)等。 - 存储温度:TSTG(存储温度范围)。 - 最大焊接温度:TSOL(对于含铅/锡元件体的最大焊接温度)、对于无铅元件体的最大焊接温度。 - 最大结温:结温的最大值。

功能详解: Spartan-7 FPGA的直流和交流特性在商业(C)、工业(I)和扩展(Q)温度范围内被指定。除了操作温度范围外,所有直流和交流电气参数对于特定速度等级都是相同的。但是,只有选定的速度等级和/或设备在每个温度范围内可用。

应用信息: Spartan-7 FPGA适用于需要高性能和低功耗的应用。-1L设备特别适用于对静态功率有更低要求的应用。

封装信息: 可用的设备和封装组合可以在Xilinx网站上找到的7系列FPGA概述(DS180)和XA Spartan-7汽车FPGA数据表:概述(DS171)中找到。
