Key Points:

Largest product offering, in one family, of any Programmable Logic supplier. (15 Devices, 3,000 - 125,000 logic Gates, 3,900 - 250,000 System gates).

XC4000E is backwards compatible to old XC4000 family.

Note:

XC4025E and XC4028EX array sizes are the same. Additional EX routing means utilization is higher, therefore useable gates are higher.
