Version: **


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



FX3S uses a 16-bit data bus in the general-purpose parallel 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.
