FG1156: 1156-lead Fine-pitch Ball Grid Array
Note: The FG(G)1156 package is discontinued. See
http://www.xilinx.com/support/documentation/spartan-3_customer_notices.htm.
The 1,156-lead fine-pitch ball grid array package, FG1156, supports two different Spartan-3 devices, namely the XC3S4000
and the XC3S5000. The XC3S4000, however, has fewer I/O pins, which consequently results in 73 unconnected pins on the
FG1156 package, labeled as “N.C.” In Table 110 and Figure 53, these unconnected pins are indicated with a black diamond
symbol ().
The XC3S5000 has a single unconnected package pin, ball AK31, which is also unconnected for the XC3S4000.
All the package pins appear in Table 110 and are sorted by bank number, then by pin name. Pairs of pins that form a
differential I/O pair appear together in the table. The table also shows the pin number for each pin and the pin type, as
defined earlier.
On ball L29 in I/O Bank 2, the unconnected pin on the XC3S4000 maps to a VREF-type pin on the XC3S5000. If the other
VREF_2 pins all connect to a voltage reference to support a special I/O standard, then also connect the N.C. pin on the
XC3S4000 to the same VREF_2 voltage.
