Introduction
-
IEEE 1149.1-compatible boundary scan logic
support
XC4000 Series high-performance, high-capacity Field Pro-
grammable Gate Arrays (FPGAs) provide the benefits of
custom CMOS VLSI, while avoiding the initial cost, long
development cycle, and inherent risk of a conventional
masked gate array.
-
-
-
Individually programmable output slew rate
Programmable input pull-up or pull-down resistors
12 mA sink current per XC4000E output
•
•
Configured by Loading Binary File
Unlimited re-programmability
Read Back Capability
-
The result of thirteen years of FPGA design experience and
feedback from thousands of customers, these FPGAs com-
bine architectural versatility, on-chip Select-RAM memory
with edge-triggered and dual-port modes, increased
speed, abundant routing resources, and new, sophisticated
software to achieve fully automated implementation of
complex, high-density, high-performance designs.
