I/O Capabilities
The XA Spartan-3A FPGA SelectIO interface supports many popular single-ended and differential standards. Table 2 shows
the number of user I/Os as well as the number of differential I/O pairs available for each device/package combination. Some
of the user I/Os are unidirectional input-only pins as indicated in Table 2.
XA Spartan-3A FPGAs support the following single-ended standards:
3.3V low-voltage TTL (LVTTL)
Low-voltage CMOS (LVCMOS) at 3.3V, 2.5V, 1.8V, 1.5V, or 1.2V
3.3V PCI at 33 MHz
HSTL I, II, and III at 1.5V and 1.8V, commonly used in memory applications
SSTL I and II at 1.8V, 2.5V, and 3.3V, commonly used for memory applications
XA Spartan-3A FPGAs support the following differential standards:
LVDS, mini-LVDS, RSDS, and PPDS I/O at 2.5V or 3.3V
Bus LVDS I/O at 2.5V
TMDS I/O at 3.3V
Differential HSTL and SSTL I/O
LVPECL inputs at 2.5V or 3.3V
Production Status
Table 3 indicates the production status of each XA Spartan-3A FPGA by temperature range and speed grade. The table also
lists the earliest speed file version required for creating a production configuration bitstream. Later versions are also
supported.

Notes:
1.
The number shown in bold indicates the maximum number of I/O and input-only pins. The number shown in (italics) indicates the number
of input-only pins. The differential input-only pin count includes both differential pairs on input-only pins and differential pairs on I/O pins
within I/O banks that are restricted to differential inputs.
