ispDOWNLOAD下载电缆适用于所有的Lattice器件进行在系统编程的硬件连接产品。用户通过 ispLEVER或 PAC-Designer 软件完成逻辑设计并生成编程文件后，Lattice的 ispVMTM System Software 软件即可直接在 PC电路板上对器件进行编程。除下载电缆外，不需要其他的元器件即可完成对器件的编程。
该电缆支持对所有1.2 伏、1.8 伏、2.5 伏、 3.3 伏及 5.0伏核心电压器件的编程。
为了获得最大的灵活性，Lattice的编程电缆连接至USB口，使用飞线连接器至目标系统电路板。
一般下载只需连接JTAG接口的TCK、TMS、TDI、TDO和VCC、GND这6个引脚即可，其余针脚为针对不同芯片的可选信号。
Lattice's ispDOWNLOAD® Cable products are the hardware connection for in-system programming of all Lattice devices. After completion of the logic design and creation of a programming file with the ispLEVERTM or PAC-DesignerTM software, Lattice's ispVMTM System Software is used to control the programming of devices directly on the PC board. No additional components are required to program a device.
Lattice's programming cables connect to either USB or PC Parallel ports, and use fly-wire connectors to the target system board for maximum flexibility. The cables also include adapters for easy interface to widely used 1x8 and 2x5 header configurations. The cables support programming of all Lattice devices with 1.2V, 1.8V, 2.5V, 3.3V, 5.0V core voltages. Both cables are also RoHS Compliant.
Cable Options:
USB PC connection - Flywire - RoHS Compliant
Parallel PC connection - Flywire - RoHS Compliant
