5. USB Function Controller and Transceiver
The Universal Serial Bus (USB) function controller in the CP2104 is a USB 2.0 compliant full-speed device with
integrated transceiver and on-chip matching and pullup resistors. The USB function controller manages all data
transfers between the USB and the UART as well as command requests generated by the USB host controller and
commands for controlling the function of the UART and GPIO pins.
The USB Suspend and Resume signals are supported for power management of both the CP2104 device as well
as external circuitry. The CP2104 will enter Suspend mode when Suspend signaling is detected on the bus. On
entering Suspend mode, the CP2104 asserts the SUSPEND and SUSPEND signals. SUSPEND and SUSPEND
are also asserted after a CP2104 reset until device configuration during USB Enumeration is complete.
The CP2104 exits the Suspend mode when any of the following occur: Resume signaling is detected or generated,
a USB Reset signal is detected, or a device reset occurs. On exit of Suspend mode, the SUSPEND and SUSPEND
signals are de-asserted.
Both SUSPEND and SUSPEND temporarily float high during a CP2104 reset. If this behavior is undesirable, a
strong pulldown (10 k
) can be used to ensure SUSPEND remains low during reset.
The logic level and output mode (push-pull or open-drain) of various pins during USB Suspend is configurable in
the PROM. See Section 8 for more information.
6. Asynchronous Serial Data Bus (UART) Interface
The CP2104 UART interface consists of the TX (transmit) and RX (receive) data signals as well as the RTS, CTS,
DSR, DTR, DCD, and RI control signals. The UART supports RTS/CTS, DSR/DTR, and X-On/X-Off handshaking.
The UART is programmable to support a variety of data formats and baud rates. If the Virtual COM Port drivers are
used, the data format and baud rate are set during COM port configuration on the PC. If the USBXpress drivers are
used, the CP2104 is configured through the USBXpress API. The data formats and baud rates available are listed
in Table 10.
