FTDI Chip USB Hi-Speed Serial/Hub Module

FTDI USB Hi-Speed Serial/Hub Module is a USB interface expansion module which has a USB 2.0 Hi-Speed hub chip that supports up to three external downstream USB ports (two by a dual USB connector and one by the DIL connector pins). The FTDI USB Hi-Speed Serial/Hub Module is designed for connecting FTDI V2DIPx modules to expand the number of interfaces, and can also be used as a hub device or an FT4232H evaluation module. By using the FT4232H USB Hi-Speed four-port bridge chip, which handles all the USB signaling and protocols, the module can easily support up to four flexible interfacing ports. It is ideal for quickly proving the functionality of adding USB to a target design.

Features

  • USB 2.0 Hi-Speed compatible
  • One standard Type-A USB header to connect to the host
  • USB Hi-Speed FT4232H device for USB-Serial/Bitbang communications; entire USB protocol handled by the USB module
  • USB 2.0 Hi-Speed hub controller integrated to support up to three downstream USB ports
  • USB hub controller and FT4232H are USB bus-powered with no external power supply needed
  • External power input pin available to supply external downstream USB ports
  • Support for USB suspend and resume
  • Four Asynchronous serial interfaces available, which include two independent MPSSE engines
  • Defaults to four RS232 interfaces
  • One dual-port USB A socket and 0.1” pitch header to support up to three downstream USB ports
  • Green/Amber status LED for downstream USB port 2&3
  • LED indicating power supply to external downstream USB ports
  • Onboard EEPROM 93LC56 for FT4232H configuration
  • UHCI / OHCI / EHCI host controller compatible

Specifications

  • Asynchronous Serial data transfer rates from 300 baud to 12 Mbaud at TTL levels
  • Synchronous Serial (MPSSE) data rates of up to 30Mbps on JTAG, SPI, and I2C

Applications

  • Expansion module for the FTDI V2DIPx modules to expand USB ports and interfaces
  • Rapid USB integration into existing electronic systems
  • Prototyping platform for USB interface on new systems
