Table 54: Serial Peripheral Interface (SPI) Connections (Continued)
Voltage Compatibility
Available SPI Flash PROMs use a single 3.3V supply volt-
age. All of the FPGA’s SPI Flash interface signals are within
I/O Bank 2. Consequently, the FPGA’s VCCO_2 supply
voltage must also be 3.3V to match the SPI Flash PROM.
Power-On Precautions if 3.3V Supply is Last in
Sequence
Spartan-3E FPGAs have a built-in power-on reset (POR)
circuit, as shown in

Initialization Indicator. Active Low.
Goes Low at start of configuration during
Initialization memory clearing process.
Released at end of memory clearing,
when mode select pins are sampled. In
daisy-chain applications, this signal
requires an external 4.7 kΩ pull-up
resistor to VCCO_2.
FPGA Configuration Done. Low during
configuration. Goes High when FPGA
successfully completes configuration.
Requires external 330 Ω pull-up resistor
to 2.5V.
Program FPGA. Active Low. When
asserted Low for 300 ns or longer, forces
the FPGA to restart its configuration
process by clearing configuration
memory and resetting the DONE and
INIT_B pins once PROG_B returns
High. Requires external 4.7 kΩ pull-up
resistor to 2.5V. If driving externally with
a 3.3V output, use an open-drain or
open-collector driver or use a current
limiting series resistor.

Data Sheet Minimum Time from V

(VCCO_2)
before beginning the configuration process.
The SPI Flash PROM is powered by the same voltage sup-
ply feeding the FPGA's VCCO_2 voltage input, typically
3.3V. SPI Flash PROMs specify that they cannot be
accessed until their V
sheet voltage, followed by an additional delay. For some
devices, this additional delay is as little as 10 µs as shown in
Table

Active during configuration. If
SPI Flash PROM requires > 2
ms to awake after powering on,
hold INIT_B Low until PROM is
ready. If CRC error detected
during configuration, FPGA
drives INIT_B Low.
Low indicates that the FPGA is
not yet configured.
Must be High to allow
