P599 - FPGA-based USM Main PMC

USM Universal Submodules make PMC modules more flexible than ever. The main PMC P599 gets its specific function through the IP cores implemented inside its onboard FPGA. This function can be changed at any time through implementation of different IP cores. The corresponding line drivers are realized on the USM which is simply plugged on the P599.

The same USM may also be used on XMCs, conduction-cooled PMCs or M-Module main modules. A new design is then limited to the USM module and the FPGA content andtherefore saves development time and costs. A Nios soft processor implemented in the Cyclone II FPGA by Altera provides local intelligence where needed. The I/O signals are led to the USM and then to a SCSI connector at the front of the P599.

The growing range of Wishbone-based standard IP cores from MEN comprise different UARTs, Ethernet, fieldbus interfaces, graphics, digital I/O etc. For users who like to write and/or implement specific IP cores on their own a complete FPGA USM development kit is available.

The USM concept has been developed for harsh environments. Therefore, the P599 uses robust connectors to the USM, while all other components are soldered, and operates in a -40 to +85 °C temperature range with qualified components.

The P599 is aPMC mezzanine card suitable for any PMC compliant host carrier board in any type of bus system, i.e. CPCI, VME or on any type of stand-alone SBC. Appropriate PMC carrier cards in 3U, 6U and other formats are available from MEN or other manufacturers.
