TQ144: 144-lead Thin Quad Flat
Package
The XC3S50, the XC3S200, and the XC3S400 are avail-
able in the 144-lead thin quad flat package, TQ144. Conse-
quently, there is only one footprint for this package as shown
in Table 18 and Figure 9.
The TQ144 package only has four separate VCCO inputs,
unlike the other packages, which have eight separate
VCCO inputs. The TQ144 package has a separate VCCO
input for the top, bottom, left, and right. However, there are
still eight separate I/O banks, as shown in Table 18 and
Figure 9. Banks 0 and 1 share the VCCO_TOP input, Banks
2 and 3 share the VCCO_RIGHT input, Banks 4 and 5
share the VCCO_BOTTOM input, and Banks 6 and 7 share
the VCCO_LEFT input.
All the package pins appear in Table 18 and are sorted by
bank number, then by pin name. Pairs of pins that form a dif-
ferential 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.
