Description
The
USB 2.0 Hi-Speed to MPSSE cable
contains a small internal electronic circuit board, utilising the
FTDI FT232H, which is encapsulated into the USB connector end of the cable, this handles all the USB
signalling and protocols. The cable provides a fast, simple way to connect devices with 3.3 Volt digital
interfaces to USB. For full details of the IC, consult the FT232H datasheet, this is available from
The integrated FT232H device incorporates a command processor called the Multi-Protocol Synchronous
Serial Engine (MPSSE). The purpose of the MPSSE command processor is to communicate with devices
which use synchronous protocols (such as JTAG, SPI or I
2
C) in an efficient manner. Full details are
available in the
The cable is terminated by ten individual wires with single pole connectors which can be interfaced to a
male header. Cable signals are compliant with CMOS logic at 3.3 volts.
The FT232H is a single channel USB 2.0 Hi-Speed (480Mb/s) to UART/FIFO IC. It can be configured in a
variety of industry standard serial or parallel interfaces, such as MPSSE - JTAG, SPI, I
2
C.
The C232HM MPSSE cable is easily configured into each interface e.g. JTAG, SPI, I
2
C via the application
software.
The cable is powered from a USB host port and is USB 2.0 Hi-Speed compatible. The cable is 0.5m long
and supports a data transfer up to 30Mbps in MPSSE mode.
The C232HM MPSSE cable requires USB device drivers, available free from
The
D2XX driver is used with application software to directly access the FT232H in the cable though a DLL.
This is illustrated in the Figure 1-1
The C232HM MPSSE cable uses the FTDI’s FT232H USB to serial IC device.
