LatticeECP2 Part Number Description
Ordering Information
Note:þLatticeECP2 devices are dual marked. For example, the commercial speed grade LFE2-50E-7F672C is also
marked with industrial grade -6I (LFE2-50E-6F672I). The commercial grade is one speed grade faster than the
associated dual mark industrial grade. The slowest commercial speed grade does not have industrial markings.
The markings appear as follows:
