FIFO Availability for Interfacing with LPC MCU ?

Hi all,


I'm planning to use LPC 55S6X MCU's in one of my product and wanted to add USB3.0 connectivity for more data rate.

Now, if we employ FTDI 601Q/ Cypress EZ USB FX3  chips (USB 3.0 to FIFO Bridge IC), as a middle IC bw Host and main MCU (LPC 55X), they atleast need 16/32 bit wide FIFO bus on the MCU end to interface with.


In  LPC 55S6X Data sheet, FIFO mentioning is in the following:

* 2 exclusive HIgh speed SPI fifo with 8 entries

* Every Flexicom (0-7) has a FIFO for implementing USART, SPI, I2S.

* Two independent result FIFOs for ADC, each contains 16 entries.


I want to know, if I can use any of the above FIFO's (especially SPI/ADC FIFO's) without any difficulty to interface with my USB 3.0 to FIFO Bridge IC

Am I missing any technical difficulties in implementing this ?


Thanks in advance.
