APEX 20K Programmable Logic Device Family Data Sheet
Figure 33. Relationship between VCCIO & VCCINT for 3.3-V PCI Compliance
Figure 34 shows the typical output drive characteristics of APEX 20K
devices with 3.3-V and 2.5-V VCCIO. The output driver is compatible with
the 3.3-V PCI Local Bus Specification, Revision 2.2 (when VCCIO pins are
connected to 3.3 V). 5-V tolerant APEX 20K devices in the -1 speed grade
are 5-V PCI compliant over all operating conditions.
