-1 speed grade devices are compliant with PCI Local Bus
...and More
Features
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, available
without consuming additional device logic.
–
–
Operate with a 2.5-V internal supply voltage
In-circuit reconfigurability (ICR) via external configuration
devices, intelligent controller, or JTAG port
ClockLockTM and ClockBoostTM options for reduced clock delay,
clock skew, and clock multiplication
–
–
–
Built-in, low-skew clock distribution trees
100% functional testing of all devices; test vectors or scan chains
are not required
–
Pull-up on I/ O pins before and during configuration
■
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 buses
Up to six global clock signals and four global clear signals
■
