描述 Description

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.

Operating at USB Hi-Speed 480Mbps rate, this fast dual channel bridge chip features either a flexible serial interface or parallel FIFO interface, with data transfer speeds up to 40Mbytes/s. Using a serial EEPROM interface, this device can be configured for a wide variety of asynchronous and synchronous serial standards, such as JTAG, SPI, I2C and UART as well as synchronous and asynchronous parallel FIFO interfaces. In addition, this device features a synchronous, half-duplex FT1248 bus, which allows an engineer to trade off bandwidth for pin count using 1, 2, 4, or 8 data lines at up to 30Mbytes/s. 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 68 pin device is available in QFN packaging, and is ROHS compliant.
