ispDOWNLOAD Cables for the PC
• CABLE AND PARALLEL PORT ADAPTER FACILITATE IN-SYSTEM PROGRAMMING OF ISP™ DEVICE FAMILIES — Simplifies In-System Programming — Ideal for Design Prototyping and Debugging
The ispDOWNLOAD Cables for the PC are designed to facilitate in-system programming of all Lattice Semiconductor ISP devices on a printed circuit board directly from the parallel port of a PC. With in-system programmability, hardware functions can be programmed and modified in real-time on the system board to give additional product features, shorten system design and debug cycle time, enhance product manufacturability and simplify field upgrades. After completion of the logic design and

creation of a JEDEC file by the ispDesignEXPERT™ Systems or ispGDX Development System, Lattice’s ispVM™ System software programs devices on the endproduct board. Programming signals are generated from the parallel port of a PC and directed through the ispDOWNLOAD Cable to the device. With one of these cables and a connector on a board, no additional components are required for programming. The ispVM System software automatically generates the appropriate ISP command, programming address and data from the JEDEC fuse map information. ispVM System software is included with all Lattice design tool products.
