原廠Lattice Semiconductor USB Flywire Cable下載線（HW-USBN-2B），可編程、USB to JTAG
Programmable Cable, Lattice Programmable Products, USB to JTAG, Flywires, 6ft Length
HW-USBN-2B is a 1.2V to 3.3V USB programming cable that provides hardware connection for in-system programming of all Lattice devices. 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 will automatically generate the appropriate functions based on the selected device. It features connections to multiple PC interfaces (USB (v.1.0, v.2.0) and PC parallel port). It is easy-to-use programming connectors and ideal for design prototyping and debugging.
- 是一款 1.2V 至 3.3V USB 編程電纜，為所有萊迪思裝置的系統內編程提供硬體連接。編程電纜提供的功能與萊迪思可編程裝置上的可用功能相對應。
- 由於某些設備包含不同的編程功能，因此編程電纜提供的特定功能可能取決於所選的目標設備。
- ispVM System/Diamond Programmer 軟體將根據所選設備自動產生對應的函數。
- 它具有與多個 PC 介面（USB（v.1.0、v.2.0）和 PC 並行連接埠）的連接。
- 它是易於使用的編程連接器，非常適合設計原型和調試。
- ［VCC］： programming voltage (Input) connect to VCC or VCCJ plane of the target device
