FT4232HL USB UART Interface (MIO 18-21)
[Figure 2-1, callout 7]
The FT4232HL U151 quad USB-UART on the ZCU104 board provides three level-shifted
UART connections through the single micro-AB USB connector J164.
• Channel A is configured to support the JTAG chain.
• Channel B implements UART0 MIO18/19 connections.
• Channel C implements UART1 MIO20/21 connections.
• Channel D implements UART2 PL-side bank 28 4-wire interface.
The USB UART interface circuit is shown in Figure 3-13. The FTDI FT4232HL data sheet is
available on the Silicon Labs website [Ref 15].
