The SMT300 is a single site module carrier developed to provide access to a TIM Module over the CompactPCI bus running at 33MHz with a 32-bit data bus. The card has an “on-board” JTAG ACT8990 controller. This allows Code Composer Studio and 3L Diamond applications to be used to debug/upload software to a Module. A single buffered ComPort with conflict protection is available on the chassis front panel. This has the versatility to access any of four ComPorts from the Module. The main connection to the 3U CompactPCI bus is via the Module’s Global Bus. A single ComPort is also mapped to the CompactPCI bus providing support for application boot and data transfer. 1 Mbyte of SRAM is mapped on to the Global Bus and can be accessed by the Module as a global resource or by the CompactPCI Bridge. A 3.3 volt supply will be available at the fixing pillars for the Module. This supply will be taken from the CompactPCI edge connector. An “on-board” Sundance Digital Bus (SDB) interface to the CompactPCI Bridge allows the card to be interfaced to SDB standard modules. The National Instrument’s Extensions for Instrumentation (PXI) signals are utilized allowing multiple SMT300’s to be synchronized in a system.
To aid in system development and debugging of designs using the SMT300, a cPCI / PXI -> PCI converter can be purchased.
