CP2110-EK
5.2. Universal Serial Bus (USB) Interface (P2)
A Universal Serial Bus (USB) connector (P2) is provided to facilitate connections to the USB interface on the
CP2110. See Table 2 for the USB pin definitions.
5.3. UART Signals (P1, J1)
An RS-232 transceiver circuit and DB9 connector (P1) are provided on the evaluation board to connect the CP2110
virtual serial port to external serial devices. See Table 3 for the RS-232 P2 pin descriptions. The J1 connector is
provided to facilitate direct access to the CP2110’s UART signals. Shorting blocks on J1 are required to connect
the UART signals to P2. See Table 4 for J1 pin descriptions.
