1. For reference purposes, the 2x10 connector on the HW7265-DL2 or HW7265-DL2A is equivalent to Tyco 102387-1. This will interface to
standard 100-mil spacing 2x5 headers, or a 2x5 keyed, recessed male connector such as the 3M N2510-5002RB.
Programming Software
ispVM System is the preferred programming management software tool for all Lattice devices and download
cables. The latest version of ispVM System is always available for download from the Lattice web site at
