Configuration
Spartan-3E FPGAs are programmed by loading configura-
tion data into robust, reprogrammable, static CMOS config-
uration latches (CCLs) that collectively control all functional
elements and routing resources. The FPGA’s configuration
data is stored externally in a PROM or some other non-vol-
atile medium, either on or off the board. After applying
power, the configuration data is written to the FPGA using
any of seven different modes:
•
•
•
•
•
•
Furthermore, Spartan-3E FPGAs support MultiBoot config-
uration, allowing two or more FPGA configuration bit-
streams to be stored in a single parallel NOR Flash. The
FPGA application controls which configuration to load next
and when to load it.

Package
Master Serial from a Xilinx Platform Flash PROM
Serial Peripheral Interface (SPI) from an
industry-standard SPI serial Flash
Byte Peripheral Interface (BPI) Up or Down from an
industry-standard x8 or x8/x16 parallel NOR Flash
Slave Serial, typically downloaded from a processor
Slave Parallel, typically downloaded from a processor
Boundary Scan (JTAG), typically downloaded from a
processor or system tester.
All Spartan-3E devices provided in the same package are pin-compatible as further described in Module 4:
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 XC3S500E is available in the VQG100 Pb-free package and not the standard VQ100. The VQG100 and VQ100 pin-outs are identical
and general references to the VQ100 will apply to the XC3S500E.
