Quad Channel Hi-Speed USB Type-C to Multipurpose UART/JTAG/SPI/I2C with Dual PD Ports
FT4233HPQ
This Hi-Speed USB device with Type-C/PD 3.0 controller IC fully supports the latest USB Type-C and Power Delivery (PD) standards enabling support for power negotiation with the ability to sink or source current to a USB host device.
This has one Dual-role PD port (PD port 1) which also carries the USB data communication. This can switch between the roles of sinking power from the host to power the peripheral, and sourcing power to charge the host computer.
A second included PD port (PD port 2) is a power sink and can be used to connect an external power source/charger. This can provide power to the peripheral board as well as charging the host via PD port 1.
This is a USB 2.0 Hi-Speed (480Mb/s) to UART IC. It has the capability of being configured in a variety of industry standard serial or parallel interfaces.
This fast quad channel bridge chip features 4 UARTs. Two of these have an option to independently configure an MPSSE engine allowing to operate as two UART/Bit-Bang ports plus two MPSSE engines used to emulate JTAG, SPI, I2C, Bit-bang or other synchronous serial modes.
The I/O structure is 3.3V with built-in tolerance for 5V, allowing the designer maximum flexibility when interfacing with FPGAs. On-board voltage regulation provides 3.3V and 1.8V supplies from a 5V source, as well as a power-on-reset function.
FTDI provides royalty-free Virtual Com Port (VCP) and D2XX drivers for Microsoft Windows, Mac OS, and Linux. This 76 pin device is available in LQFP packaging, and is ROHS compliant.
