    Question: What is the maximum throughput on the P to U channel in FX3S™?



    FX3S uses a 16-bit data bus in the General Programmable Interface (GPIF), which can work up to 100 MHz. Here, the theoretical maximum is 200 MBps—that is, 100 MHz * 2 bytes. The practical testing shows a result of 187 MBps.


    Note: The GPIF data width of FX3S can be either 8 or 16 bits. For maximum throughput, it should be configured to 16 bits.
