USB-I
2
C is implemented using the USB and I
2
C components of PSoC 5LP. The SCL (P12_0) and
SDA (P12_1) lines from the PSoC 5LP are connected to the SCL (P1_2) and SDA (P1_3) lines of
the PSoC 4 I
2
C. The USB-I
2
C bridge currently supports I
2
C speed of 50 kHz, 100 kHz, 400 kHz, and
1 MHz.

bridge functionality.
3.5 USB-UART Bridge
The onboard PSoC 5LP can also act as a USB-UART bridge to transfer and receive data from the
PSoC 4 device to the PC via the COM terminal software. When the USB Mini-B cable is connected
to J10 of the PSoC 4000 Pioneer Kit, a device named
KitProg USB-UART is available under Ports
(COM & LPT) in the Device Manager. For more information about the USB-UART functionality, see
Using PSoC 5LP as a USB-UART Bridge on page 118 .
