The FT232HQ-REEL is a single channel USB to multipurpose UART/FIFO IC, operating at USB high-speed 480Mbps rate, this fast single channel bridge chip features either a flexible serial interface or parallel FIFO interface, with data transfer speeds up to 40Mbps. 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 the new 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 30Mbps. 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 3.3 and 1.8V supplies from a 5V source, as well as a power-on-reset function.
