FT4232HQ USB-UART Interface
[Figure 2-1, callout 7]
The FT4232HQ U27 Quad USB-UART on the VCU1525 board provides two UART connections
through the single Micro-AB USB connector J13.
• Channel AD is configured to support the JTAG chain.
• Channel AC implements a 2-wire TX/RX UART connection to the MSP432 BMC U19.
• Channel BD implements a 2-wire level-shifted TX/RX UART connection to the XVU9P
U13.
• Channel BC is not used.
The USB UART interface circuit is shown in Figure 3-4. For finer details see the VCU1525
schematic 0381795, page 31 [Ref 7].
