Product Features.
This high-speed, single-channel bridge chip operates at USB High Speed (480Mbps) and has a flexible serial or parallel FIFO interface. Using the serial EEPROM interface, the device can be configured for a variety of asynchronous and synchronous serial standards such as JTAG, SPII2C and UART as well as synchronous and asynchronous parallel FIFO interfaces. In addition, the device features the new synchronous, half-duplex FT1248 bus.
It allows engineers to utilise 1, 2, 4 or 8 data lines to achieve up to 30Mbps. the I/0 architecture is 3.3V with a 5V withstand voltage, giving designers maximum flexibility when interfacing with FPGAs. An on-chip integrated LDO regulator converts from a 5V supply to 3.3V and 1.8V, as well as a power-on reset function. The entire USB protocol is handled on-chip, eliminating the need for USB-specific firmware programming. Multi-Protocol Synchronous Serial Engine (MPSSE) simplifies the design of synchronous serial protocols (USB to JTAG, I2C, SPI or bit-bang). CPU mode FIFO interface mode simplifies the design of the CPU interface. With fast serial interface option, adjustable timeout receive buffer.FTDI provides royalty-free virtual COM port and D2XX drivers for Microsoft Windows (XP - Windows 10) Apple Mac OSX and Linux.
