Features...
■ Low-cost, high-density, register-rich CMOS programmable logic
device (PLD) family (see Table 1)
– 2,500 to 16,000 usable gates
– 282 to 1,500 registers
■ System-level features
– In-circuit reconfigurability (ICR) via external configuration
devices or intelligent controller
– Fully compliant with the peripheral component interconnect
Special Interest Group (PCI SIG) PCI Local Bus Specification,
Revision 2.2 for 5.0-V operation
– Built-in Joint Test Action Group (JTAG) boundary-scan test (BST)
circuitry compliant with IEEE Std. 1149.1-1990 on selected devices
–MultiVolt
TM
I/O interface enabling device core to run at 5.0 V,
while I/O pins are compatible with 5.0-V and 3.3-V logic levels
– Low power consumption (typical specification is 0.5 mA or less in
standby mode)
■ Flexible interconnect
–FastTrack
®
Interconnect continuous routing structure for fast,
predictable interconnect delays
– Dedicated carry chain that implements arithmetic functions such
as fast adders, counters, and comparators (automatically used by
software tools and megafunctions)
– Dedicated cascade chain that implements high-speed, high-fan-in
logic functions (automatically used by software tools and
megafunctions)
– Tri-state emulation that implements internal tri-state nets
■ Powerful I/O pins
■ Programmable output slew-rate control reduces switching noise
