Because the three supply inputs must be valid to release

mum rate is affected by the package inductance. Conse-
quently, the ball grid array and chip-scale packages
(CP132, FT256, FG456, FG676, and FG900) allow a faster
ramp rate than the quad-flat packages (VQ100, TQ144, and
PQ208).
Configuration Data Retention, Brown-Out
The FPGA’s configuration data is stored in robust CMOS
configuration latches. The data in these latches is retained
even when the voltages drop to the minimum levels neces-
sary to preserve RAM contents. This is specified in
Table 30, page
If, after configuration, the V
below its data retention voltage, clear the current device
configuration using one of the following methods:
•
•
The POR circuit does not monitor the VCCO_4 supply after
configuration. Consequently, dropping the VCCO_4 voltage
does not reset the device by triggering a Power-On Reset
(POR) event.
No Internal Charge Pumps or Free-Running
Oscillators
Some system applications are sensitive to sources of ana-
log noise. Spartan-3 FPGA circuitry is fully static and does
not employ internal charge pumps.
The CCLK configuration clock is active during the FPGA
configuration process. After configuration completes, the
CCLK oscillator is automatically disabled unless the Bit-
stream Generator (BitGen) option Persist=Yes. See Mod-
ule 4:
Spartan-3 FPGAs optionally support a featured called
tally Controlled Impedance
cation, the DCI logic uses an internal oscillator. The DCI
logic is only enabled if the FPGA application specifies an I/O
standard that requires DCI (LVDCI_33, LVDCI_25, etc.). If
DCI is not used, the associated internal oscillator is also dis-
abled.
In summary, unless an application uses the Persist=Yes
option or specifies a DCI I/O standard, an FPGA with no
external switching remains fully static.
