The Lattice HW7265-DL3A ispDOWNLOAD Cable and Adapter enables in-system programming (ISP) of Lattice Semiconductor devices directly from a PC parallel port. This accessory supports real-time hardware modification on production boards, accelerating design cycles, streamlining manufacturing, and enabling field updates across multiple Lattice device families. The cable interfaces via a 25-pin parallel port adapter with RJ-45 connector and offers flexible target board connectivity through flywire, 1×8, 2×5, or 1×10 (.100″ center-spacing) connectors. Programming voltage range spans 1.8V to 5V, accommodating legacy and modern FPGA/CPLD architectures.

– Compatibility & Integration
Works with all Lattice programmable devices spanning FPGA and CPLD families. The 1×10 connector option integrates with the ispDOWNLOAD USB cable for configuration status feedback on newer architectures. Standard JTAG-compatible pin definitions (TDI/TDO, TMS, TCK) ensure predictable integration with established ISP workflows.
