Hi. For a few proto PCBAs, we are sourcing CYUSB3014-BZXI devices but the datecode is '12xx'. Concerned about the 'ES' devices which had some erratas. Specifically, unable to soft-enumerate on the 'ES' version of the component.
Have some questions:
1) Will the engineering samples of the CYUSB3014-BZXI devices have the 'ES' laser markings ? This datecode does not but wish to understand the markings.
2) Which datecode of the CYUSB3014-BZXI is considered to be bug free silicon ? Saw some mention of Rev B and Rev C silicon but how can we determine if our device is one of these iterations with erratas ?
Please assist asap as so far, unable to locate any document with these details.
Thanks.
