Recently I am considering to design a macro USB dongle for Android (as HID/CDC device). Due to its limited space, I am trying to find a USB micro which can operate without external crystal. I know Microchip/Cypress can do, but STM claims that USB has to work with external crystal.


Can I use IRC(4MHz) of KL24/25Z as clock source for USB OTG?
