MOTOROLA 01-W3324F Memory Expansion Module

MOTOROLA  01-W3324F    Memory Expansion Module

Features:

Single-Slot cPCI Board

PowerPC Series Microprocessor

The MCP750HA is a single-slot Hot Swappable CompactPCI board equipped with a PowerPC™ Series microprocessor.

The board can be purchased in a standard (MCP750) or Hot Swap capable (MCP750HA) version with 32MB, 64MB, 128MB, or 256MB of ECC DRAM.

The complete MCP750HA consists of the base (main) board plus an:

• ECC DRAM module (RAM300) for memory

• Optional PCI Mezzanine Card (PMC) for additional versatility

For example, in a VME chassis power system powered by FAB 0340-1049.

the accessory can accept 24V DC power via 12 input terminals (split into redundant positive/negative paths for reliability) and distribute it to 24 downstream 

devices—such as 4x MVME162-223 modules (6 terminals each) or 8x sensors (3 terminals each).

This centralized layout reduces wire length by 40% compared to direct wiring from the power supply, making troubleshooting (e.g., identifying a loose connection) faster and safer.

Robust Protection Against Wiring Risks

The integrated 30A resettable circuit breaker trips when the total load exceeds the accessory’s capacity—critical for preventing damage to power supplies and peripherals.

For instance, if a MVME172PA-652SE module develops a short circuit, the breaker shuts down power to the 01-W3324F before the fault spreads to the FAB 0340-1049 power supply.

Reverse polarity protection adds another layer of safety: if a technician accidentally swaps positive/negative wires during maintenance, the accessory blocks current flow, avoiding burnout of sensitive components like MVME147S-1 memory modules.
