Implemented on a compact 75.04 mm x 23.37 mm PCB, the module has an FTDI FT4232H USB 2.0 Hi-Speed to UART/MPSSE chip which supports data rates of 40Mb/s and can take care of all USB signalling and protocols. This new USB Hi-Speed serial/hub Module offers three external downstream USB ports – two via a dual USB connector and another via the 0.1” pitch, DIL connector pins. The FT4232H also features four serial interfaces that can be configured for either asynchronous or synchronous operation – two with the option to be independently configured via an MPSSE engine (allowing the FT4232H to function as two UART/bit-bang ports plus two MPSSE engines which can be used to emulate JTAG, SPI, I2C, bit-bang or other synchronous serial modes).
The module’s GL850G USB 2.0 hub controller chip supports both individual and gang power management modes. It can be optionally customised using an EEPROM memory located on the module, enabling customization of PID/VID and other more complex settings.
Highly suited to development purposes this module can serve as a prototyping platform, proving the validity of adding USB connectivity to new and legacy system designs.
By connecting the hub module to the USB socket of a V2DIPx module, together they can function as a single module with an extended selection of interface options. The FT4232H hub module can also serve as a hub device connected to a PC or the FT4232H evaluation module.
The new FTDI FT4232H USB Hi-Speed serial/hub module (FT-MOD-4232HUB) is available now at a cost of $35.00 for single units. Volume pricing is available on request.
