Notes:
1. All voltages are relative to ground.
2. For the design of the power distribution system consult the 7 Series FPGAs PCB Design Guide (UG483) [Ref 4].
3. If V
CCINT
and V
CCBRAM
are operating at the same voltage, V
CCINT
and V
CCBRAM
should be connected to the same supply.
4. Configuration data is retained even if V
CCO
drops to 0V.
5. Includes V
CCO
of 1.2V, 1.35V, 1.5V, 1.8V, 2.5V, and 3.3V at ±5%.
6. The lower absolute voltage specification always applies.
7. See Table 9 for TMDS_33 specifications.
8. A total of 200 mA per bank should not be exceeded.
9. V
CCBATT
is required only when using bitstream encryption. If battery is not used, connect V
CCBATT
to either ground or V
CCAUX
