The latest version of ispVM System is always available for download from the Lattice web site at www.latticesemi.com/software. PAC-Designer is the design tool for Lattice ispPAC and ispCLOCK devices. PAC-Designer can also be used to pro- gram these devices. If using PAC-Designer for programming, pay special attention to the notes in this document, and the PAC-Designer system help. 2 Lattice Semiconductor ispDOWNLOAD Cables Refer to the following table when connecting a ţy-wire 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 ispDOWN- LOAD 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 conŢguration. Table 2.

For devices that have a V pin, the V must be connected to the cable's V and a 0.1µF decoupling capacitor is required on V CCJ CCJ CC, CCJ close to the device. Please refer to the device data sheet to determine if the device has a V pin. CCJ 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 ţy-wire TRST/DONE wire to TRST. If the device DONE signal is available on the board (or if both TRST and DONE are available), connect the USB ţy-wire TRST/DONE wire to DONE. Please make sure the correct setting is selected in ispVM (Options, Cable and I/O Port Setup). This will tell ispVM whether the TRST/DONE cable is used as a TRST or a DONE signal. 4. For newer FPGA devices (i.e. LatticeECP/EC), 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). 3 Lattice Semiconductor ispDOWNLOAD Cables Table 3.

Please refer to the ispDOWNLOAD Cable ispEN Pin section below for detailed information on connecting the ispEN/ENABLE pin. 2. Please refer to the ispDOWNLOAD Cable TRST Pin section below for detailed information on connecting the TRST pin. 3. The DONE and INITN signals are only available on the ispDOWNLOAD USB cable. These signals are inputs to the cable and can be used to help verify device conŢguration. 4. Please refer to the device data sheet. Not all packages have the ENABLE or TRST pin. 5. When using PAC-Designer software to program ispPAC devices, do not connect this pin. 6. When using these connections, be sure to select the correct settings in the Cable and I/O Port Setup dialog in the ispVM System software. Connecting the ispDOWNLOAD Cable The target board must be un-powered when connecting, disconnecting, or reconnecting the ispDOWNLOAD Cable. Always connect the ispDOWNLOAD Cable’s GND pin (black wire), before connecting any other JTAG pins. Failure to follow these procedures can result in damage to the target programmable device. ispDOWNLOAD Cable TRST Pin Connecting the board TRST pin to the cable TRST pin is not recommended. Instead, connect the board TRST pin to Vcc. If the board TRST pin is connected to the cable TRST pin, instruct ispVM to drive the TRST pin high as fol- lows: 1. Select the Options menu item 2. Select Cable and I/O Port Setup 3. Check the TRST/Reset Pin Connected check box 4. Select the Set High radio button If the proper option is not selected, the TRST pin will be driven low by ispVM. Consequently, the BSCAN chain will not work because the chain will be locked into RESET state. ispDOWNLOAD Cable ispEN Pin The following pins should be grounded: • BSCAN pin of the 2000VE devices • ENABLE pin of MACH4A3/5-128/64, MACH4A3/5-64/64 and MACH4A3/5-256/128 devices. 4 Lattice Semiconductor ispDOWNLOAD Cables However, the user has the option of having the BSCAN and ENABLE pins driven by the ispEN pin from the cable. In this case, ispVM must be conŢgured to drive the ispEN pin low as follows: 1. Select the Options menu item 2. Select Cable and I/O Port Setup 3. Check the ispEN/BSCAN Pin Connected check box 4. Select the Set Low radio button Table 4. ispDOWNLOAD Cable Feature Summary HW7265-DL3, HW7265-DL3A, HW-DL-3B, Feature HW-USBN-2A HW-USB-2A HW-USB-1A HW-DLN-3C HW-DL-3C HW7265-DL2 HW7265-DL2A PDS4102-DL2 PDS4102-DL2A USB X X X PC-Parallel X X X X X X 1.2V Support X X 1.8V Support X X X X X X X 2.5-5.0V Support X X X X X X X X X 2x5 Connector X X X X X X X 1x8 Connector X X X X X X X Flywire X X X X X Lead-free XX Construction Available for order X X Each ispDOWNLOAD Cable ships with two small connectors that help you keep the ţywires organized.
