Discussion - Hardware / FT4222H QuadSPI Mode Max Throughput Question
« on: April 30, 2020, 09:22:45 AM »
In the datasheet of FT4222H, it is called Max Throughput 52.8Mbps when in SPI Master Mode.
  
I am wondering how to get Max Throughput value in QuadSPI Mode.

There is an attached file.

Question 1. As in Figure 2. does Max Throughput 52.8Mbps mean the transmission rate of 16bits (DATA0 & 1) DATA?


Question 2. I think Payload = 17.6 Mbps as shown in Figure 3. Are there any problems with the calculation of Max Throughput and Payload?



Thank you.
