FTDI USB to UART Interface Bridge VQFN 56-Pin
FTDI USB 2.0 Hi-Speed to UART interface bridge with dual MPSSE for JTAG, SPI & I²C. VQFN 56-pin, 1.62V to 1.98V.
The FTDI USB to UART Interface Bridge is a 5th generation USB device designed for versatile serial and parallel interface configurations. As a USB 2.0 Hi-Speed (480Mb/s) to UART integrated circuit, it provides a robust solution for advanced data transfer requirements.
This device features four UARTs, two of which can be independently configured with a Multi-Protocol Synchronous Serial Engine (MPSSE). This flexibility allows the bridge to operate as two UART or bit-bang ports alongside two MPSSE engines, enabling the emulation of JTAG, SPI, I²C, and other synchronous serial modes. The entire USB protocol is managed directly on the chip, removing the need for any USB-specific firmware programming.
Advanced Features
- USB 2.0 high-speed (480Mbits/second) and full-speed (12Mbits/second) compatible
- Two MPSSE engines on channels A and B for simplified synchronous serial protocol design
- Independent baud rate generators with adjustable receive buffer timeouts
- Support for USB suspend and resume conditions via PWREN#, SUSPEND#, and RI# pins
- Fully assisted hardware or X-On/X-Off software handshaking
- UART interface supporting 7/8 bit data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity
- Auto-transmit enable control for RS485 applications using the TXDEN pin
- Low operating and USB suspend current with configurable I/O drive strength and slew rate
- Compatible with bus-powered, self-powered, and high-power bus-powered USB configurations
- Supports UHCI/OHCI/EHCI host controllers and USB bulk data transfer mode
- Dedicated Windows DLLs available for USB to JTAG, SPI, and I²C applications
Supplied in a 56-pin VQFN package, this interface bridge operates reliably in ambient temperatures ranging from -40°C to 85°C, making it suitable for demanding environments.
