ispDOWNLOAD Cables

Lattice ispDOWNLOAD cables are designed to facilitate

in-system programming for all Lattice Semiconductor

ISP™ devices directly from a PC. With in-system pro-

grammability, 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.

ispDOWNLOAD Cables

After you complete your logic design and create a pro-

gramming file with the ispLEVER

you can use ispVM™ System software to program

devices on your board. The ispVM System software

automatically generates the appropriate ISP com-

mands, programming addresses and programming data

based on information stored in the programming file and

parameters you set in ispVM. Programming signals are

then generated from the USB or parallel port of a PC

and directed through the ispDOWNLOAD Cable to the

device. No additional components are required for pro-

gramming.

ispVM System software is included with all Lattice

design tool products and is available for download from

the Lattice web site at www.latticesemi.com.

ispDOWNLOAD Cable Pin Definitions

The functions provided by the ispDOWNLOAD cables

correspond with available functions on Lattice program-

mable devices. Since some devices contain different

programming features, the specific functions provided

by the ispDOWNLOAD cable may depend on the

selected target device. ispVM System software will

automatically generate the appropriate functions based

on the selected device. See Table 1 for an overview of

the ispDOWNLOAD cable functions.
