Hi there,
Quick question regarding CYPD312X parts.
Is there any difference in these parts on the silicon level other than the ID? Or is it entirely default firmware feature set/port role that governs these numbers? As far as I can tell, the 3120/3123/3125 look to all have the same pinout, and it's stated explicitly that the 3120 can be used as a replacement for the 3123, since the 3123 was not released when the SDK 3.0.2 documentation was last updated.
Am I correct in this?
Thanks!

Hi ,
The difference is entirely default firmware feature set/port role that governs these numbers and all of Cypress CCGx chip have pre-programmed bootloader when ship out from Cypress. So that CYPD3125 will be pre-programmed I2C bootloader and CYPD3123 will be pre-programmed usb bootloader.
You can use CYPD3125 firmware for CYPD3123, but the firmware bootloader will be change to CYPD3125 also.
Best Regards,
Lisa
