RAM500 Connectors
Bottom Side Memory Expansion Connector (P1)
RAM500 memory expansion modules are populated with one or two connectors. If the module
is to be used in tandum with a second RAM500 module, the “bottom” module will have two
connectors: one to mate with the MVME5100 host board (P1), and one to mate with the “top”
RAM500 module (J1). The “top” RAM500 module has only one connector, since it needs to
mate only with the RAM500 module directly underneath it and because an added connector on
a tandum RAM500 configuration would exceed the height limitations in some backplanes. If
only one RAM500 module is being used, a top module, single connector configuration is used.
A 4H plug and receptacle are used on both boards to provide a 4 millimeter stacking height
between dual RAM500 cards and the host board.
The following subsections specify the pin assignments for the connectors on the RAM500.
The bottom side connector on the RAM500 is a 140-pin AMP 0.6mm Free Height mating plug.
This plug includes common ground contacts that mate with standard AMP receptacle
assemblies or AMP GIGA assemblies with ground plates. A single memory expansion module
will have 1 bank of SDRAM for a maximum of 5Mbytes of memory. Attaching a second memory
module to the first module will provide 2 banks of SDRAM with a maximum of 1Gigabytes.
