RPi HUB Module Datasheet Version 1.0 Document Reference No.: FT 000700 Clearance No.: FTDI 297 Future Technology Devices International Ltd Datasheet RPi HUB Module Datasheet RPi HUB Module connects to a Raspberry-Pi computer and expands the number of interfaces that can be accessed downstream from a Host. RPi HUB Module also provides a dual channel USB 2 UART/245FIFO/SPI/I C/JTAG/GPIO interface converter. 1 Introduction 2 The FT2232H based RPi HUB Module is a USB to UART/245FIFO/SPI/I C/JTAG/GPIO interface expansion module targeted at connecting to Raspberry-Pi computer to expand the number of interfaces. However, it is not limited to this application. It can also be used as a hub device or an FT2232H evaluation module. The module has a USB 2.0 Hi-Speed hub chip which supports up to three external downstream USB ports: 2 via a dual USB connector and 1 via the DIL connector pins. Additionally, by utilising the FT2232H USB Hi-Speed dual-port bridge chip which handles all the USB signalling and protocols, the module can easily support up to two flexible interfacing ports. It is ideal for development purposes to quickly prove functionality of adding USB to a target design. This module utilises the GL850G USB 2.0 hub controller which provides a low-cost and widely used USB 2.0 hub solution, to provide up to 4 downstream USB ports. The GL850G is a single chip USB hub solution. The GL850G is a full function solution which supports both Individual/Gang power management modes and two- colour (green/amber) status LED. The FT2232H used on the Module is FTDIs 5th generation of USB devices. The FT2232H is a USB 2.0 Hi- Speed (480Mb/s) to UART/MPSSE IC. The device features two interfaces that can be configured for asynchronous or synchronous serial communications or Parallel FIFO Interface. The two interfaces can also be independently configured via an MPSSE engine. This allows the FT2232H to operate as two UART/Bit-Bang 2 ports or two MPSSE engines which can be used to emulate JTAG, SPI, I C, Bit-bang or other synchronous serial modes. All I/Os of the RPi HUB Module operate at 3.3V TTL and are 5V safe. FT2232Hs MPSSE interfaces are controlled over USB, for details on MPSSE see: Application Note AN 108. For more details on FT2232H see: FT2232H datasheet DS FT2232H. 1.1 Ordering Information Product Name Order Code Description RPi HUB Module RPi-HUB-Module USB HUB and USB to dual channel multi interface converter module designed for Raspberry Pi.
