This is FT4232HQ – Hi-Speed USB 2.0 Slave to Quad Channel UART / Serial Converter – IC. The FT4232H is FTDI’s 5th generation of USB devices. The FT4232H is a USB 2.0 High Speed (480Mb/s) to UART/MPSSE ICs. The device features 4 UARTs. Two of these have an option to independently configure an MPSSE engine. This allows the FT4232H to operate as two UART/Bit-Bang ports plus two MPSSE engines used to emulate JTAG, SPI, I

2C, Bit-bang or other synchronous serial modes.

Note:

1. The product may vary in shape, color, and markings as compared to the image shown depending upon availability.
2. Refer to datasheet in the ATTACHMENTS section for more info. regd. the product.

Features:

1. Single chip USB to quad serial ports with a variety of configurations.
2. Entire USB protocol handled on the chip. No USB specific firmware programming required.
3. USB 2.0 High Speed (480Mbits/Second) and Full Speed (12Mbits/Second) compatible.
4. Two Multi-Protocol Synchronous Serial Engine (MPSSE) on channel A and channel B, to simplify synchronous serial protocol (USB to JTAG, I2C, SPI or bit-bang) design.
5. Independent Baud rate generators.
6. RS232/RS422/RS485 UART Transfer Data Rate up to 12Mbaud. (RS232 Data Rate limited by
7. external level shifter).
8. FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.
9. Optional traffic TX/RX indicators can be added with LEDs and an external 74HC595 shift
10. register.
11. Adjustable receive buffer timeout.
12. Support for USB suspend and resume conditions via PWREN#, SUSPEND# and RI# pins.
