Features...
I
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
EPROM or intelligent controller
–
Fully compliant with the peripheral component interconnect
(PCI) standard
–
Built-in Joint-Test Action Group (JTAG) boundary-scan test (BST)
circuitry compliant with IEEE Std. 1149.1-1990 on selected devices
–
MultiVolt
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 less than 0.5 mA
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
Peripheral register for fast setup and clock-to-output delay
