Etron eSP268 Webcam Controllers

 

eSP268 is a highly integrated USB 2.0 High-Speed (HS) and Full-Speed (FS) compatible Web camera controller. It has 3 built-in LDOs to provide power for CIS module and USB controller. As a result, eSP258 can reduce total BOM cost significantly and meet system requirements in a smaller form factor.
