Additional Fast Capture Input Latch (Spartan-XL Family
Only)
The Spartan-XL family OB has an additional optional latch
on the input. This latch is clocked by the clock used for the
output flip-flop rather than the input clock. Therefore, two
different clocks can be used to clock the two input storage
elements. This additional latch allows the fast capture of
input data, which is then synchronized to the internal clock
by the IOB flip-flop or latch.
To place the Fast Capture latch in a design, use one of the
special library symbols, ILFFX or ILFLX. ILFFX is a trans-
parent-Low Fast Capture latch followed by an active High
input flip-flop. ILFLX is a transparent Low Fast Capture latch
followed by a transparent High input latch. Any of the clock
inputs can be inverted before driving the library element,
and the inverter is absorbed into the IOB.
IOB Output Signal Path
Output signals can be optionally inverted within the IOB,
and can pass directly to the output buffer or be stored in an
edge-triggered flip-flop and then to the output buffer. The
functionality of this flip-flop is shown in

Spartan-XL Family V
Spartan-XL FPGAs have an optional clamping diode con-
nected from each I/O to V
ringing transients back to the 3.3V supply rail. This clamping
action is required in 3.3V PCI applications. V
a global option affecting all I/O pins.
Spartan-XL devices are fully 5V TTL I/O compatible if V
clamping is not enabled. With V
Spartan-XL devices will begin to clamp input voltages to
one diode voltage drop above V
patibility is maintained but full 5V I/O tolerance is sacrificed.
The user may select either 5V tolerance (default) or 3.3V
PCI compatibility. In both cases negative voltage is clamped
to one diode voltage drop below ground.
Spartan-XL devices are compatible with TTL, LVTTL, PCI
3V, PCI 5V and LVCMOS signalling. The various standards
are illustrated in
