Welcome to FTDI’s USB Hi- Speed support page
For the latest news about
FTDI USB Hi-Speed devices and products.
FTDI
is pleased to announce
the availability of updated versions of libMPSSE-I2C and libMPSSE-SPI :
14th February 2012
libMPSSE-I2C can now
support NAKing the last byte while reading data, 3-phase-clocking(with clock rate
adjustments made in the library), Drive-Only-Zero, transferring multiple
MPSSE commands and data in a single USB frame leading to no delays between
START, ADDRESS, DATA and STOP phases, and options to transfer non-standard
frames over the I2C bus. libMPSSE-SPI has been updated to support
transferring multiple bytes over USB frame and full-duplex transfers.
Additionally, both these libraries now support 64 bit Linux, has improved
error handling, unified samples for Windows and Linux, and updated scripts
to build and execute the samples.

Press Release : New USB Hi-Speed to Digital Level
Interface UART Cabling Solutions : October 2011
FTDI have added 2 new cables to its range of USB 2.0 Hi-Speed to Digital
Level cables. The USB-UART cables provide a USB Hi-Speed interface to
RS232 UART – at 3.3V signal levels. For more information
please refer to the
datasheet.
Latest News
: 3 new application notes
illustrating FT232H, MPSSE and the new USB-MPSSE cables : October
2011
FTDI have just released 2 new
application notes which show practical examples of using the new USB-MPSSE
cables to interface to SPI and I2C busses. These provide full explanation
and source code examples of how to configure the MPSSE of the new cables.
An additional application note details an application which uses the
FT232H to measure the USB VBUS voltage and current in a USB connection.

USB Hi-Speed Application Notes
To assist and make it easier to
design with our Hi-Speed devices, FTDI have developed a number of
application notes which provide a starting point to designers using their
USB Hi-Speed ICs. These are listed as follows:

The Hi-Speed devices
contain a configurable means of interfacing synchronous serial
interfaces to USB. This makes use of the FTDI Multi-Protocol Synchronous
Serial Engine (MPSSE). This is explained in the following application
note:
AN_135 :
MPSSE Basics
To make effective use of the MPSSE
within the USB Hi-Speed devices, and simplify the software design stage of
the application development, FTDI have developed 2 DLLs : one for I2C and
one for SPI. These are described and the download links can be found in
the following documents:

USB Hi-Speed Development Modules
To allow designers to quickly get up to speed and prototype their software
and hardware, FTDI offer a number of development modules. In general
specific ICs have their own development modules. These are listed in the
following table:
| IC |
Development Module |
Datasheet |
| FT232H |
The UM232H module provides the ability to configure the FT232H
as either a serial data transfer interface (JTAG/SPI/I2C/UART - as
well as the new FT1248 protocol) or parallel FIFO interface, at
speeds up to 40MByte/s. Built to conform to a standard 0.6” 28 pin
DIP socket, this module can be either self or bus-powered. |
UM232H Datasheet |
| FT2232H |
The FT2232H Mini Module is a USB to dual channel
serial/MPSSE/FIFO interface converter. The module provides access
to device I/O interfaces via 2 double row 0.1" pitch male
connectors. |
FT2232H Mini-Module Datasheet |
| FT4232H |
The FT4232H Mini Module is a USB-to-serial/MPSSE interface
converter. The development module provides access to the quad
channel serial / MPSSE converter interfaces via a set of 2 double
row 0.1" pitch male connectors. |
FT4232H Mini-Module Datasheet |
| UM232H-B |
The UM232H-B module provides the ability to configure the FT232H as either a serial data transfer interface (JTAG/SPI/I2C/UART – as well as the new FT1248 protocol) or parallel FIFO interface, at speeds up to 40MByte/s – in a small form factor where the USB connectivity is created with the PCB tracks as opposed to a separate connector. |
