HW-USBN-2A Overview

HW-USBN-2A is an ispDOWNLOAD cable product that provides hardware connectivity for in-system programming of all Lattice devices. It is primarily used to support the programming and configuration of Lattice FPGA (Field-Programmable Gate Array) and CPLD (Complex Programmable Logic Device) devices. After completing the logic design and creating programming files using Lattice Diamond, ispLEVER Classic, or PAC-Designer software, you can program the devices directly on the PC board using Lattice Diamond Programmer or Lattice's ispVM system software. No additional components are required for device programming.
