(4 Gbits), roughly equivalent to a daisy-chain with 720
XC3S1600E FPGAs. This is a limit only for serial
daisy-chains where configuration data is passed via the
FPGA’s DOUT pin. There is no such limit for JTAG chains.
Configuration Sequence
The Spartan-3E configuration process is three-stage pro-
cess that begins after the FPGA powers on (a POR event)
or after the PROG_B input is asserted. Power-On Reset
(POR) occurs after the V
2 supplies reach their respective input threshold levels.
After either a POR or PROG_B event, the three-stage con-
figuration process begins.
1. The FPGA clears (initializes) the internal configuration
2. Configuration data is loaded into the internal memory.
3. The user-application is activated by a start-up process.

Initialization
Configuration automatically begins after power-on or after
asserting the FPGA PROG_B pin, unless delayed using the
FPGA’s INIT_B pin. The FPGA holds the open-drain INIT_B
signal Low while it clears its internal configuration memory.
Externally holding the INIT_B pin Low forces the configura-
tion sequencer to wait until INIT_B again goes High.
The FPGA signals when the memory-clearing phase is
complete by releasing the open-drain INIT_B pin, allowing
the pin to go High via the external pull-up resistor to
VCCO_2.
Loading Configuration Data
After initialization, configuration data is written to the
FPGA’s internal memory. The FPGA holds the Global
Set/Reset (GSR) signal active throughout configuration,
holding all FPGA flip-flops in a reset state. The FPGA sig-
nals when the entire configuration process completes by
releasing the DONE pin, allowing it to go High.
The FPGA configuration sequence can also be initiated by
asserting PROG_B. Once released, the FPGA begins
clearing its internal configuration memory, and progresses
through the remainder of the configuration process.
