Table 3 lists the relationship between the VCC and VPP voltage levels and the required
logic level for VCCSEL and VPPSEL pins. A high logic level means the pin should be
connected to VCC, while a low logic level means the pin should be connected to GND.
At a 3.3-V operation, all EPC2 inputs are 5.0-V tolerant, except for DATA, DCLK, and
nCASC
pins. The DATA and DCLK pins are used only to interface between the EPC2
device and the FPGA it is configuring. Table 4 lists the voltage tolerences of all EPC2
device pins.
If one EPC1, EPC2, or EPC1441 configuration device is powered at 3.3 V, the nSTATUS
and CONF_DONE pull-up resistors must be connected to 3.3 V. If these configuration
devices are powered at 5.0 V, the nSTATUS and CONF_DONE pull-up resistors can be
connected to either 3.3 V or 5.0 V.
