,
Table 13
, and
Table 26
. Updated TMDS DC characteristics
in
Table 13
. Updated I/O Test Method values in
Table 26
. Added Simultaneously Switching Output limits in
Table 28
. Updated DSP48A timing symbols, descriptions, and values in
Table 34
. Added power-on timing in
Table 45
. Added CCLK specifications for Commercial in
Table 46
through
Table 48
. Updated Slave Parallel
timing in
Table 51

07/16/07
2.0
Added Low-power options and updated typical values for quiescent current in
Table 9
. Updated DSP48A
timing in
Table 34
and
Table 35
.

2.1
Improved V
CCAUXT
and V
CCO2T
POR minimum in
Table 4
and updated V
CCO
POR levels in
Figure 10
. Added
V
IN
to Recommended Operating Conditions in
Table 7
and added reference to
XAPP459
, “Eliminating I/O
Coupling Effects when Interfacing Large-Swing Single-Ended Signals to User I/O Pins.” Reduced typical
I
CCINTQ
and I
CCAUXQ
quiescent current values by 20%-44% in
Table 9
. Increased V
IL
max to 0.4V for
LVCMOS12/15/18 and improved V
IH
min to 0.7V for LVCMOS12 in
Table 10
. Changed V
OL
max to 0.4V and
V
OH
min to V
CCO
–0.4V for LVCMOS15/18 in
Table 11
. Added reference to V
CCAUX
in
Simultaneously
Switching Output Guidelines
. Removed DNA_RETENTION limit of 10 years in
Table 14
since number of
Read cycles is the only unique limit. Updated speed files to v1.31 in
Table 16
and elsewhere. Updated IOB
Setup and Hold times with device-specific values in
Table 19
. Added reference to Sample Window in
Table 20
. Updated IOB Propagation times with device-specific values in
Table 21
. Improved SSTL_18_II
SSO value in
Table 28
. Improved F
BUFG
for -4 to 334 MHz in
Table 32
. Added references to 375 MHz
performance via SCD 4103 in
Table 32
,
Table 37
,
Table 38
, and
Table 39
. Added explanatory footnotes to
DSP48A Timing
tables. Simplified DSP48A F
MAX
to value with all registers used in
Table 35
. Improved
FBUFG in
Table 32
for -4 speed grade. Updated CCLK output maximum period in
Table 46
to match
minimum frequency in
Table 47.
Replaced BPI with SPI specification descriptions in
Table 52
. Corrected BPI
Figure 14
and
Table 54
from falling edge to rising edge. Added references to Spartan-3 Generation User
Guides. Updated links.
03/11/09
2.2
Changed typical quiescent current temperature from ambient to quiescent. Updated selected I/O standard
DC characteristics. Removed PCIX IOSTANDARD due to limited PCIX interface support. Added T
IOPI
and
T
IOPID
to
Table 21
. Updated BPI configuration waveforms in
Figure 14
and updated
Table 55
. Removed
references to SCD 4103.

IN
in
Table 7
including adding note 4. Also, added note 2 to I
L
in
Table 8
to note potential leakage between pins of a differential pair. Added note 6 to
Table 10
. Updated
notes 5 and 6 in
Table 12
. Corrected symbols for T
SUSPEND_GTS
and T
SUSPEND_GWE
in
Table 44
.
