Programming Cables

Lattice Programming Cable products are the hardware connection for in-system programming of all Lattice devices. After you complete your logic design and create a programming file with the Lattice Diamond®/ispLEVER® Classic development tools, you can use Diamond Programmer or ispVM™ System software to program devices on your board. The ispVM System/Diamond Programmer software automatically generates the appropriate programming commands, programming addresses and programming data based on information stored in the programming file and parameters you set in Diamond Programmer/ispVM System. Programming signals are then generated from the USB or parallel port of a PC and directed through the programming cable to the device. No additional components are required for programming.
Diamond Programmer/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/programmer.

Programming Cable Pin Definitions

The functions provided by the programming cables correspond with available functions on Lattice programmable devices. Since some devices contain different programming features, the specific functions provided by the programming cable may depend on the selected target device. ispVM System/Diamond Programmer software automatically generates the appropriate functions based on the selected device. See Table 3.1 for an overview of the programming cable functions.
Table 3.1. Programming Cable Pin Definitions.

Programming Cable Pin| Name| Programming Cable Pin Type| Description
---|---|---|---
VCC| Programming Voltage| Input| Connect to VCCIO or VCCJ plane of the target device. Typical ICC = 10 mA. The target board

provides the VCC supply/reference for the cable.

TDO/SO| Test Data Output| Input| Used to shift data out via the IEEE1149.1 (JTAG) programming standard.
TDI/SI| Test Data Input| Output| Used to shift data in via the IEEE1149.1 programming standard.

Figure 3.5. Programming Cable In-System Programming Interface for the PC (HW7265-DL2 or HW7265-DL2A)*

Note: For reference purposes, the 2 x 10 connector on the HW7265-DL2 or HW7265-DL2A is equivalent to Tyco 102387-1. This will interface to standard 100-mil spacing 2 x 5 headers, or a 2 x 5 keyed, recessed male connector such as the 3M N2510-5002RB.

Programming Software

Diamond Programmer and ispVM System for Classic devices is the preferred programming management software tool for all Lattice devices and download cables. The latest version of Lattice Diamond Programmer or ispVM System software is available for download from the Lattice web site at www.latticesemi.com/programmer.

Target Board Design Considerations

A 4.7 kΩ pull-down resistor is recommended on the TCK connection of the target board. This pull-down is recommended to avoid inadvertent clocking of the TAP controller induced by fast clock edges or as VCC ramps up. This pull-down is recommended for all Lattice programmable families.
The I2C signals SCL and SDA are open drain. A 2.2 kΩ pull-up resistor to VCC is required on the target board. Only VCC values of 3.3 V and 2.5 V for I2C are supported by the HW-USBN-2B cables.
For Lattice device families that feature low power, it is recommended to add a 500 Ω resistor between VCCJ and GND during the programming interval when a USB programming cable is connected to a very low power board design. A FAQ is available that discusses this in more depth at:
http://www.latticesemi.com/en/Support/AnswerDatabase/2/2/0/2205
The JTAG programming port speed may need to be governed when using the programming cables connected to customer PCBs. This is especially important when there is long PCB routing or with many daisy-chained devices. The Lattice programming software can adjust the timing of TCK applied to the JTAG programming port from the cable. This low-precision port setting of TCK depends on many factors, including the PC speed and the type of cable used (parallel port, USB or USB2). This software feature provides an option to slow the TCK for debug or noisy environments. A FAQ is available that discusses this in more depth at: http://www.latticesemi.com/en/Support/AnswerDatabase/9/7/974.aspx
The USB download cable can be used to program Power Manager or ispClock products with Lattice programming software. When using the USB cable with the Power Manager I devices, (POWR604, POWR1208, POWR1208P1), you must slow do TCK by a factor of 2. A FAQ is available that discusses this in more depth at:
http://www.latticesemi.com/en/Support/AnswerDatabase/3/0/306.aspx

Notes:

• For older Lattice ISP devices, a 0.01 μF decoupling capacitor is required on ispEN/ENABLE of the target board.
• For HW-USBN-2A/2B, the target board supplies the power – Typical ICC = 10 mA. For devices that have a VCCJ pin, the VCCJ must be connected devices, connect the appropriate bank VCCIO to the cable’s VCC. A 0.1 μF decoupling capacitor is required on VCCJ or VCCIO close to the device. sheet to determine if the device has a VCCJ pin or what VCCIO bank governs the target programming port (this may not be the same as a target 3. Open drain signals. Target board should have ~2.2 kΩ pull-up resistor connected to the same plane to which VCC is connected. HW-USBN-2B cables to VCC.
• When using PAC-Designer® software to program ispPAC or ispClock devices, do not connect TRST/DONE.
• If using a cable older than HW-USBN-2B, connect a +5 V external supply between iCEprogM1050 pin 4 (VCC) and pin 2 (GND).
• For HW-USBN-2B, only VCC values of 3.3 V thru 2.5 V are supported for I2C.

Connecting the Programming Cable

The target board must be unpowered when connecting, disconnecting, or reconnecting the programming cable. Always connect the programming 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.

Programming 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/Diamond Programmer to drive the TRST pin high.

To configure ispVM/Diamond Programmer to drive TRST pin high:

• Select the Options menu item.
• Select Cable and I/O Port Setup.
• Select the TRST/Reset Pin-Connected checkbox.
• Select the Set High radio button.

If the proper option is not selected, the TRST pin is driven low by ispVM/Diamond Programmer. Consequently, the BSCAN chain does not work because the chain is locked into a RESET state.

Programming 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.

However, you have the option of having the BSCAN and ENABLE pins driven by the ispEN pin from the cable. In this case, ispVM/Diamond Programmer must be configured to drive the ispEN pin low as follows:
To configure ispVM/Diamond Programmer to drive ispEN pin low:

1. Select the Options menu item.
2. Select Cable and I/O Port Setup.
3. Select the ispEN/BSCAN Pin Connected checkbox.
4. Select the Set Low radio button.

Each programming cable ships with two small connectors that help you keep the flywires organized. The following manufacturer and part number is one possible source for equivalent connectors:

• 1 x 8 Connector (for example, Samtec SSQ-108-02-T-S)
• 2 x 5 Connector (for example, Samtec SSQ-105-02-T-D)

The programming cable flywire or headers are intended to connect to standard 100-mil spacing headers (pins spaced 0.100 inch apart). Lattice recommends a header with length of 0.243 inches or 6.17 mm. Though, headers of other lengths may work equally well.

Appendix A. Troubleshooting the USB Driver Installation

It is essential that you install the drivers before connecting your PC to the USB cable. If the cable is connected before installing the drivers, Windows will try to install its own drivers that may not work.
If you have attempted to connect the PC to the USB cable without first installing the appropriate drivers, or have trouble communicating with the Lattice USB cable after installing the drivers, follow the steps below:

1. Plug in the Lattice USB cable. Choose Start > Settings > Control Panel > System.

2. In the System Properties dialog box, click the Hardware tab and Device Manager button. Under Universal Serial Bus controllers, you should see Lattice USB ISP Programmer. If you do not see this, look for the Unknown Device with the yellow flag. Double click on the Unknown Device icon.

3. In the Unknown device Properties dialog box, click Reinstall Driver.

4. Select Browse my computer for driver software.
   Browse to the isptools\ispvmsystem directory for the Lattice EzUSB driver.
   Browse to the isptools\ispvmsystem\Drivers\FTDIUSBDriver directory for the FTDI FTUSB driver.

5. For Diamond installations, browse to lscc/diamond/data/vmdata/drivers. Click Next.

6. Select Install this Driver software anyway. The system updates the driver.

7. Click Close and finish installing the USB driver.

8. Under Control Panel >System >Device Manager > Universal Serial Bus Controllers should include the following: For the Lattice EzUSB Driver: Lattice USB ISP Programmer device installed.

For the FTDI FTUSB Driver: USB Serial Converter A and Converter B devices installed
