XC7A25T集成电路（IC）的FPGA（现场可编程门阵列）规格书PDF中文资料

ntroduction

Artix®-7 FPGAs are available in -3, -2, -1, -1LI, and -2L

speed grades, with -3 having the highest performance. The

Artix-7 FPGAs predominantly operate at a 1.0V core voltage.

The -1LI and -2L devices are screened for lower maximum

static power and can operate at lower core voltages for

lower dynamic power than the -1 and -2 devices,

respectively. The -1LI devices operate only at

VCCINT = VCCBRAM = 0.95V and have the same speed

specifications as the -1 speed grade. The -2L devices can

operate at either of two VCCINT voltages, 0.9V and 1.0V and

are screened for lower maximum static power. When

operated at VCCINT = 1.0V, the speed specification of a -2L

device is the same as the -2 speed grade. When operated at

VCCINT = 0.9V, the -2L static and dynamic power is reduced.

Artix-7 FPGA DC and AC characteristics are specified in

commercial, extended, industrial, expanded (-1Q), and

military (-1M) 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 -1M

speed grade military device are the same as for a -1C speed

grade commercial device). However, only selected speed

grades and/or devices are available in each temperature

range. For example, -1M is only available in the

defense-grade Artix-7Q family and -1Q is only available in

XA Artix-7 FPGAs.

All supply voltage and junction temperature specifications

are representative of worst-case conditions. The parameters

included are common to popular designs and typical

applications.
