ispDOWNLOAD Cables
Programming Flywire and Connection Reference
Refer to Table 2 when connecting a flywire download cable to systems that use the 1x8-position or 2x5-position
connectors. For newer Lattice FPGA families, a 1x10 connector used in conjunction with the ispDOWNLOAD USB
cable adds support for the DONE and INITN signals. Both of these signals are inputs to the cable, and can be used
to help verify device configuration.

1. For devices that have a V CCJ pin, the V CCJ must be connected to the cable’s V CC, and a 0.1μF decoupling capacitor is required on V CCJ
close to the device. Please refer to the device data sheet to determine if the device has a V CCJ pin.
2. For older Lattice ISP devices, a 0.01μF decoupling capacitor is required on ispEN/ENABLE of the target board.
3. The TRST and DONE pin is multiplexed on the ispDOWNLOAD USB cable. If the device TRST signal is available on the board, connect the
USB flywire TRST/DONE wire to TRST. If the device DONE signal is available on the board (or if both TRST and DONE are available), con-
nect the USB flywire TRST/DONE wire to DONE. Please make sure the correct setting is selected in ispVM/Diamond Programmer (Options,
Cable and I/O Port Setup). This will tell ispVM/Diamond Programmer whether the TRST/DONE cable is used as a TRST or a DONE signal.
4. A 4.7K pull-down resister is recommended on TCK of the target board.
Table 3 lists the recommend pin connections. Please contact Lattice technical support for information on unlisted
device families. (e-mail: techsupport@latticesemi.com, phone: 1-800-LATTICE).
