USB UART Interface
[Figure 2, callout 24]
The FT4232HL U8 mul-funcon USB-UART on the VCU128 board provides three level-shied
UART connecons through the single micro-AB USB connector J2.
• Channel A is congured in JTAG mode to support the JTAG chain
• Channel B implements 4-wire UART0 (level-shied) FPGA U1 bank 67 connecons
• Channel C implements 4-wire UART1 (level-shied) FPGA U1 bank 67 connecons
• Channel D implements 2-wire (level-shied) SYSCTLR U42 bank 501 connecons
The USB UART interface circuit is shown in the following gure. The FTDI FT4232HL data sheet
is available on the Future Technology Devices Internaonal Ltd. website.
