Pinout tables for XC4000-Series devices follow. Pinout data is offered in two forms, as device-specific and package-specific
tables. Device-specific tables include all packages for each XC4000-Series device. They follow the pad locations around
the die, and include boundary scan register locations. Package-specific tables include all XC4000-Series devices available
in a given package. These tables are especially useful in determining which pads should be avoided, in case of a future
transition to a different device in the same package.
All pinouts defined at the time of publication are included in these tables. Additional information may be available. Call your
local sales office or see the Xilinx W
EB
LINX at http://www.xilinx.com for the latest information.
Note:
This table includes standard user-programmable I/O. It also includes the TDI, TCK, and TMS pins, which can function as
user-programmable I/O if not used for boundary scan. In addition to the I/O listed in this table, the M0 and M2 pins can be
used as inputs only; the M1 and TDO pins can be used as outputs only. All of these pins must be called out using special
library symbols. The XACT software does not use them by default. (See
.)
