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.
After you complete your logic design and create a pro-
gramming file with the ispLEVER® development tools,
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.
