GE VMIVME-7807RC
The Real-World Problem It Solves
You know the headache: legacy VME systems that need upgrading but your customer is in the EU or has corporate sustainability mandates requiring RoHS-compliant hardware. The standard VMIVME-7807 contains lead in the solder and other restricted substances. The VMIVME-7807RC eliminates this compliance roadblock—it’s the same 1.8 GHz Pentium M performance, same dual Gigabit Ethernet, same passive cooling reliability, but with lead-free solder and RoHS-certified components. You get modern computing power in a VME form factor without violating environmental regulations or corporate green policies.
Where you’ll typically find it:
-
Upgraded Mark VI Speedtronic systems in EU power plants where RoHS compliance is mandatory
-
Military and aerospace applications requiring environmentally restricted components
-
Industrial control systems in environmentally regulated jurisdictions (California, EU, Japan)
Bottom line: It delivers the same VME-based Pentium M performance as the standard VMIVME-7807 while meeting strict environmental standards for hazardous substance restrictions.

GE VMIVME-7807RC
Hardware Architecture & Under-the-Hood Logic
The VMIVME-7807RC is functionally identical to the standard VMIVME-7807, but manufactured with RoHS-compliant processes. It’s a complete Pentium M computer on a single VME card, running standard x86 operating systems while interfacing with VME backplane I/O. The “RC” suffix indicates the manufacturing process change, not a functional difference—performance, memory capacity, and I/O are identical to the non-RoHS version.
Signal flow and processing logic:
-
Processing Core: The Pentium M executes the host OS and application software with full x86 compatibility, including MMX and SSE instructions for signal processing
-
Memory Architecture: DDR SDRAM provides high-bandwidth memory access; the 855GME chipset supports dual-display graphics without external video cards
-
VME Interface: The board interfaces with VME64x backplane via standard VME protocols, allowing access to legacy I/O modules and shared memory devices
-
Network Integration: Dual Gigabit Ethernet ports
