CP2102N-A01-GQFN28 Silicon Labs, USB Bridge, USB to UART USB 2.0 UART Interface 28-QFN (5x5)

응용 프로그램 / 파라미터의 범위


The Universal Serial Bus function controller in the CP2102N is a USB 2.0 compliant full-speed device with integrated transceiver and on-chip matching and pull-up 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. The USB Suspend and Resume signals are supported for power management of both the CP2102N device as well as external circuitry. The CP2102N will enter Suspend mode when Suspend signaling is detected on the bus. On entering Suspend mode, the CP2102N asserts the SUSPEND and SUSPENDb signals. SUSPEND and SUSPENDb are also asserted after a CP2102N reset until device configuration during USB Enumeration is complete. 

The CP2102N exits Suspend mode when any of the following occur:

1. Resume signaling is detected or generated.
2. A USB Reset signal is detected.
3. A device reset occurs.
4. USB Remote Wakeup functionality is enabled and the WAKEUP pin is grounded.

On exit of Suspend mode, the SUSPEND and SUSPENDb signals are de-asserted. Both SUSPEND and SUSPENDb temporarily float high during a CP2102N reset. If this behavior is undesirable, a strong pull-down (10 kΩ) can be used to ensure SUSPENDb remains low during reset.
