- For devices that have a VCCJ pin, the VCCJ must be connected to the cable’s VCC, and a 0.1µF decoupling capacitor is required on VCCJ close to the device. Please refer to the device data sheet to determine if the device has a VCCJ pin.
- For older Lattice ISP devices, a 0.01µF decoupling capacitor is required on ispEN/ENABLE of the target board.
- 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 l ispVM/Diamond Programmer whether the TRST/DONE cable is used as a TRST or a DONE signal.
- A 4.7K pull-down resister is recommended on TCK of the target board.
Table lists the recommend pin connections. Please contact Lattice technical support for information on unlisted device families. (: techsupport@latticesemi.com, phone: 1-800-LATTICE).
