This is the primary Versal ACAP PS-side UART interface. The VCK190 USB Type-C connector J207 only supports USB2.0.
MIO42 (RX_IN) and MIO43 (TX_OUT) are connected to FTDI FT4232HL U20 USB-to-Quad-UART bridge port BD through TI SN74AVC4T245 level-shifters U18 and U21. The FT4232HL U20 port assignments are listed in the following table.
| FT4232HL U20 | Versal ACAP U1 |
|---|---|
| Port AD JTAG | VCK190 JTAG chain |
| Port BD UART0 | PS_UART0 (MIO 42-43) |
| Port CD UART1 | PL_UART1 bank 306 |
| Port DD UART2 | U20 system controller UART |
The FT4232HL UART interface connections are shown in the following figure.
