12. Universal Serial Bus Controller (USB0)
C8051F326/7 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 pullup resistors), 256 Byte FIFO block, and clock recovery
mechanism for crystal-less operation. No external components are required. The USB Function Controller
and Transceiver is Universal Serial Bus Specification 2.0 compliant.
*Note: The C8051F326/7 cannot be used as a USB Host device.
Note: This document assumes a comprehensive understanding of the USB Protocol. Terms and abbreviations used
