C8051F38x USB MCU Slide 11
The USB controller integrated into the C8051F38x family is the same controller that has been used in previous designs and has been proven through numerous USB product certifications. The Silicon Labs USB MCUs provide device side functionality for communication with a USB host. The USB module includes the serial interface engine (SIE) that provides all of the low level functionality required to communicate with the host. The SIE controls the low level packet checking and acknowledgment without firmware overhead. This simplifies the implementation of USB firmware development. All transfer types are supported using the USB controller including control, bulk, interrupt and isochronous.
