16. Universal Serial Bus Controller (USB0)
C8051F34x devices include a complete Full/Low Speed USB function for USB peripheral implementa-
tions*. The USB Function Controller (USB0) consists of a Serial Interface Engine (SIE), USB Transceiver
(including matching resistors and configurable pull-up resistors), 1k FIFO block, and clock recovery mech-
anism for crystal-less operation. No external components are required. The USB Function Controller and
Transceiver is Universal Serial Bus Specification 2.0 compliant.
