Spartan and Spartan-XL FPGA Families Data Sheet
Pin Descriptions
There are three types of pins in the Spartan/XL devices:
•
•
•
Before and during configuration, all outputs not used for the
configuration process are 3-stated with the I/O pull-up resis-
tor network activated. After configuration, if an IOB is
unused it is configured as an input with the I/O pull-up resis-
tor network remaining activated.

Eight or more (depending on package) connections to the nominal +5V supply
voltage (+3.3V for Spartan-XL devices). All must be connected, and each must be
decoupled with a 0.01 –0.1 μF capacitor to Ground.
Eight or more (depending on package type) connections to Ground. All must be
connected.
During configuration, Configuration Clock (CCLK) is an output in Master mode and
is an input in Slave mode. After configuration, CCLK has a weak pull-up resistor
and can be selected as the Readback Clock. There is no CCLK High or Low time
restriction on Spartan/XL devices, except during Readback. See
Maximum High and Low Time Specification for the Readback Clock, page 39
for an explanation of this exception.
DONE is a bidirectional signal with an optional internal pull-up resistor. As an
open-drain output, it indicates the completion of the configuration process. As an
input, a Low level on DONE can be configured to delay the global logic initialization
and the enabling of outputs.
The optional pull-up resistor is selected as an option in the program that creates
the configuration bitstream. The resistor is included by default.
PROGRAM is an active Low input that forces the FPGA to clear its configuration
memory. It is used to initiate a configuration cycle. When PROGRAM goes High,
the FPGA finishes the current clear cycle and executes another complete clear
cycle, before it goes into a WAIT state and releases INIT.
The PROGRAM pin has a permanent weak pull-up, so it need not be externally
pulled up to VCC.
The Mode input(s) are sampled after INIT goes High to determine the
configuration mode to be used.
During configuration, these pins have a weak pull-up resistor. For the most popular
configuration mode, Slave Serial, the mode pins can be left unconnected. For
Master Serial mode, connect the Mode/M0 pin directly to system ground.

Any user I/O can be configured to drive the Global
Set/Reset net GSR or the global three-state net GTS. See

Some Spartan-XL devices are available in Pb-free package
options. The Pb-free package options have the same
pinouts as the standard package options.
