哪位大侠用过 Cable III 配置Spartan3 呢?
下面是xilinx主页的说明:
The Parallel Cable III could be powered from 2.5V to 5V; however, it could only interface with 3.3V and 5V logic levels reliably. The 74HC125 buffers in the Parallel Cable III were designed to be powered with a wide VCC range, but were not designed to perform logic level translation. Do not use the Parallel Cable III to configure a part that interfaces at 2.5V levels. If this is required, you must provide your own level-shifter.
说不能进行 2.5V的配置,如果用Cable III,一定要配制成3.3V吗?
这几天在画板,麻烦各位多多指教 多谢
