Programmable I/O Lines Power Supplies and Drive Levels
The power supply pin VDDIOM1 accepts two voltage ranges. This allows the device to reach its
maximum speed either out of 1.8V or 3.3V external memories.
The maximum speed is 133 MHz on the SDCK pin and #SDCK signals loaded with 10 pF. The
load on data/address and control signals are 30 pF for power supply at 1.8V and 50 pF for power
supply at 3.3V. The data lines frequency reaches 133 MHz in DDR2 mode. The other signals
(control and address) do not go over 66 MHz.
The EBI I/Os accept two drive levels, HIGH and LOW. This allows to avoid overshoots and give
the best performance according to the bus load and external memories. Refer to the EBI Chip
Select Assignment Register for more details.
The voltage ranges and the drive level are determined by programming EBI_DRIVE field in the
Chip Configuration registers located in the Matrix User Interface.
At reset the selected default drive level is High.
At reset, the selected voltage defaults to 3.3V typical and power supply pins can accept either
1.8V or 3.3V. The user must make sure to program the EBI voltage range before getting the
device out of its Slow Clock Mode. The user must make sure to program the EBI voltage range
before getting the device out of its Slow Clock Mode.
