CP132: 132-ball Chip-scale Package
The XC3S100E, XC3S250E and the XC3S500E FPGAs
are available in the 132-ball chip-scale package, CP132.
The devices share a common footprint for this package as
shown in
Table 133
by bank number and then by pin name. 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.
Physically, the D14 and K2 balls on the XC3S100E and
XC3S250E FPGAs are not connected but should be con-

nected to VCCINT to maintain density migration compatibil-
ity.
Similarly, the A4, C1, and P10 balls on the XC3S100E
FPGA are not connected but should be connected to GND
to maintain density migration compatibility.
The XC3S100E FPGA has four fewer BPI address pins,
A[19:0], whereas the XC3S250E and XC3S500E support
A[23:0].
