Ordering Information
Spartan-3E FPGAs are available in both standard and
Pb-free packaging options for all device/package combina-
tions. All devices are available in Pb-free packages, which
adds a ‘G’ character to the ordering code. All devices are
available in either Commercial (C) or Industrial (I) tempera-
ture ranges. Both the standard –4 and faster –5 speed
grades are available for the Commercial temperature range.
However, only the –4 speed grade is available for the Indus-
trial temperature range. See Table 2 for valid device/pack-
age combinations.

Notes:
1. The –5 speed grade is exclusively available in the Commercial temperature range.
2. The XC3S500E VQG100 is available only in the -4 Speed Grade.
3. See DS635 for the XA Automotive Spartan-3E FPGAs.
Production Stepping
The Spartan-3E FPGA family uses production stepping to
indicate improved capabilities or enhanced features.
To specify only the later stepping for the -4C, append an S#
suffix to the standard ordering code, where # is the stepping
number, as indicated in Table 3.
Stepping 1 is, by definition, a functional superset of Step-
ping 0. Furthermore, configuration bitstreams generated for
any stepping are forward compatible. See Table 72 for addi-
tional details.

Status
Xilinx has shipped both Stepping 0 and Stepping 1. Designs
operating on the Stepping 0 devices perform similarly on a
Stepping 1 device. Stepping 1 devices have been shipping
since 2006. The faster speed grade (-5), Industrial (I grade),
Automotive devices, and -4C devices with date codes 0901
(2009) and later, are always Stepping 1 devices. Only -4C
devices have shipped as Stepping 0 devices.

The stepping level is optionally marked on the device using
a single number character, as shown in Figure 2, Figure 3,
and Figure 4.
