Serial Interconnection between PSoC 5LP and PSoC 64 MCU
In addition to the use as an onboard programmer, the PSoC 5LP device functions as an interface for
the USB-UART and USB-I2C bridges, as shown in
. The USB-Serial pins of the PSoC 5LP
device are hard-wired to the I2C/UART pins of the PSoC 64 MCU. These pins are also available on
the Arduino-compatible I/O headers.
