FT4232H QUAD HIGH SPEED USB TO MULTIPURPOSE UART/MPSSE IC
Datasheet Version 2.09
Clearance No.: FTDI#78
4.3 FT232 UART Interface Mode Description
The FT4232H can be configured in similar UART modes as the FTDI FT232 devices (an asynchronous
serial interface). The following examples illustrate how to configure the FT4232H with an RS232, RS422
or RS485 interfaces. The FT4232 can be configured as a mixture of these interfaces.
4.3.1 RS232 Configuration
Figure 4.1 illustrates how the FT4232H channel A can be configured with an RS232 UART interface. This
can be repeated for channels B, C and D to provide a quad RS232, but has been omitted for clarity.
