CP2108 USB UART Interface
[Figure 2-1, callout 13]
The CP2108 quad USB-UART on the ZCU106 board provides four level-shifted UART
connections through single micro-B USB connector J83. Channel 0 and 1 are PS-side MIO
connections described in the UART0 (MIO 18-19) section. Channel 2 is a PL-side connection
and Channel 3 is connected to MSP430 system controller U41. The USB UART interface
circuit is shown in Figure 3-14. The Silicon Labs CP2108 data sheet is available on the Silicon
Labs website [Ref 19].
