Интерфейсные мосты , USB в UART, FIFO, 2.97 В, 3.63 В, QFN, 48 вывод(-ов), -40 °C

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.
