At 3.3-V operation, all EPC2 inputs are 5.0-V tolerant, except DATA, DCLK,
and nCASC. The DATA, DCLK, and nCEO pins are used only to interface
between the EPC2 configuration device and the APEX II, APEX 20K,
Mercury, ACEX 1K, or FLEX 10K device it is configuring. The voltage
tolerances of all EPC2 pins at 5.0 V and 3.3 V are listed in
For more information on APEX II, APEX 20K, Mercury, ACEX 1K,
FLEX 10K, or FLEX 6000 devices, see the following documents:
