Solution
the USB-8452 does not support xSPI (Extended SPI) or OSPI (Octal SPI). The primary reasons for this are:
- Single Data Lane Limitation: The USB-8452 only supports a single data lane, which is insufficient for Octal SPI.
- Lack of DDR Support: The USB-8452 does not support Double Data Rate (DDR), a requirement for xSPI.
- Increased Data Rates: The significantly higher data rates specified by xSPI exceed the capabilities of the USB-8452.
- Technical Constraints: Other inherent technical limitations of the USB-8452 architecture prevent it from supporting these advanced SPI protocols.
These factors collectively restrict the USB-8452 from accommodating the requirements of both xSPI and OSPI.
