• Single channel USB to serial / parallel ports
with a variety of configurations.
• Entire USB protocol handled on the chip. No
USB specific firmware programming required.
• USB 2.0 Hi-Speed (480Mbits/Second) and Full
Speed (12Mbits/Second) compatible.
• Multi-Protocol Synchronous Serial Engine
(MPSSE) to simplify synchronous serial protocol
(USB to JTAG, I2C, SPI (MASTER) or bit-bang)
design.
• UART transfer data rate up to 12Mbaud.
(RS232 Data Rate limited by external level
shifter).
• USB to asynchronous 245 FIFO mode for
transfer data rate up to 8 Mbyte/Sec.
• USB to synchronous 245 parallel FIFO mode for
transfers up to 40 Mbytes/Sec
• Supports a proprietary half duplex FT1248
interface with a configurable width, bidirectional data bus (1, 2, 4 or 8 bits wide).
• CPU-style FIFO interface mode simplifies CPU
interface design.
• Fast serial interface option.
• FTDI’s royalty-free Virtual Com Port (VCP) and
Direct (D2XX) drivers eliminate the
requirement for USB driver development in
most cases.
• Adjustable receive buffer timeout.
• Option for transmit and receive LED drive
signals.
• Bit-bang Mode interface option with RD# and
WR# strobes
• Highly integrated design includes 5V to
3.3/+1.8V LDO regulator for VCORE, integrated
POR function
• Asynchronous serial UART interface option with
full hardware handshaking and modem
interface signals.
• Fully assisted hardware or X-On / X-Off
software handshaking.
• UART Interface supports 7/8 bit data, 1/2 stop
bits, and Odd/Even/Mark/Space/No Parity.
• Auto transmit enable control for RS485 serial
applications using the TXDEN pin.
• Operational mode configuration and USB
Description strings configurable in external
EEPROM over the USB interface.
• Configurable I/O drives strength (4, 8, 12 or
16mA) and slew rate.
• Low operating and USB suspend current.
• Supports self-powered, bus powered and highpower bus powered USB configurations.
• UHCI/OHCI/EHCI host controller compatible.
• USB Bulk data transfer mode (512 byte packets
in Hi-Speed mode).
• +1.8V (chip core) and +3.3V I/O interfacing
(+5V Tolerant).
• Extended -40°C to 85°C industrial operating
temperature range.
• Compact 48-pin Lead Free LQFP or QFN
package
• Configurable ACBUS I/O pins.
