Micro Memory MM-5355D Series High Performance Expansion Memory Module | Up to 4GB, 64-bit/33MHz 6U CompactPCI SDRAM Memory Buffer w/PMC site Simple Type: Expansion Memory Module

The MM-5355D is a 64-bit/33MHz 6U CompactPCI memory buffer capable of burst mode accesses at the full bus bandwidth at 33MHz. The peak transfer rate is 264 MB/s and 240 MB/s sustained. A PLD controls data management and provides single error detection and double bits detection. Up to three mezzanines provide 512MB, 1GB, 2GB, or up to 4GB of SDRAM with error detection and correction. The MM-5355D also has a 64-bit/33MHz PMC site for on-board I/O: fibre (copper or network), frame grabbers, A/D, or any rev. 2.1 PMC I/O card. Data transfers flow through a 64-bit PCI bridge which supports a dual address cycle and allows memory and an optional PMC card to be anywhere in the 64-bit address space. This 64-bit address space overcomes the 4GB limitation of the 32-bit address configuration and 256MB limitation of many 64-bit RISC processors. The bridge also supports a secondary clock which provides independent memory refresh regardless of the host processor clock activity. Reliability is ensured by burn-in and running memory diagnostics that check operations for 48 hours while temperature-cycling boards from 0° to 70° C.
