The MM-6155DT is a conduction cooled,
conformally coated 64-bit/33MHz SDRAM PMC (PCI
Mezzanine Card) with an operating
temperature of -40° C to 71° C. The card has
been designed with extended temperature devices
and board stiffeners to meet both the ANSI/VITA
20-2001 specification for Conduction Cooled PCI
Mezzanine Cards (CCPMC) and to reside on DY4™
Level 100 Conduction Cooled Single Board
Computers.PMC's have become the standard form
factor of choice for I/O on today's high
performance board level VME and CompactPCI
cards. PMC's are electrically equivalent to the
traditional PCI bus, and most VME and CompactPCI
single board computers now include one and often
two PMC sites for flexible I/O integration.
The MM-6155DT is capable of burst mode
transfers of up to 264MB/s and can easily
provide buffer expansion memory on cards with
PMC sites. It has a PLD that controls data
management and provides double bit error
detection and single bit correction.
Instead of just generating an interrupt, a
specialized linked list Mailbox DMA notifies the
host in host memory when transfers are complete
so the host does not have to poll the status of
the DMA.
Reliability is ensured by burn-in and running
memory diagnostics that check operations for 96
hours while temperature-cycling boards from
-40°C to 71° C. |
