Pinout Differences Between Virtex and Virtex-E Families
The same device in the same package for the Virtex-E and
Virtex families are pin-compatible with some minor excep-
tions, listed in Table 1 .
XCV200E Device, FG456 Package
The Virtex-E XCV200E has two I/O pins swapped with the
Virtex XCV200 to accommodate differential clock pairing.
XCV300E Device, BG432 Package
The Virtex-E XCV300E has eight pins (B26, C7, F1, F30, S
AE29, AF1, AH8, and AH24) connected to VCCINT that are
not connected in the Virtex XCV300.
XCV400E Device, FG676 Package
The Virtex-E XCV400E has two I/O pins swapped with the
Virtex XCV400 to accommodate differential clock pairing.
All Devices, PQ240 and HQ240 Packages
The Virtex devices in PQ240 and HQ240 packages do not
have VCCO banking, but Virtex-E devices do. To achieve
this, eight Virtex I/O pins (P232, P207, P176, P146, P116,
P85, P55, and P25) are now VCCO pins in the Virtex-E fam-
ily. This change also requires one Virtex I/O or VREF pin to
be swapped with a standard I/O pin.
Additionally, accommodating differential clock input pairs in
Virtex-E caused some IO_VREF differences in the XCV400E
and XCV600E devices only. Virtex IO_VREF pins P215 and
P87 are Virtex-E IO_VREF pins P216 and P86, respectively.
Virtex-E pins P215 and P87 are IO_DLL.
