While surfing the web I wordered to find out that ChipworkX uses an ATMEL processor instead of NXP.
I further looked at the product page of the AT91SAM9261S and saw ATMEL is not recommending it for new designs, instead they recommend the use of the SAM9G.
SAM9G supports USB 2.0 at full speed, runs up to 400Mhz.
I had the impression the SAM9G was pin compatible to the SAM9261S - I did not check tough.
The SAM9M10 certainly is not pin compatible - but I’m not saying I don’t like t
I believe the ARM9 cores are either real-time oriented (Cortex Rx equivalent) or “application” (i.e. higher power, higher performance) oriented (Cortex Ax equivalent).
I mentioned the LPC17xx line (Cortex-M3) because NXP provides it as a drop-in replacement for the LPC23xx line that USBizi is currently built on.
ARM considers all the “ARMx” processors to be “legacy” or “classic” processors, and the “Cortex” line is the newer upgraded version.
This could all be wrong, I’m not an expert at all in processor architectures.
