Product Introduction
Motorola MVME2301 delivers PowerPC 603 processing at 200 MHz on the VMEbus with 16 MB ECC DRAM, dual PMC expansion, 10/100 Ethernet, and serial debug port for high-performance embedded applications. The PCI chipset with Raven bridge supports 32/64-bit PMC I/O expansion through front panel and P2 connectors while VME64 extensions enable BLT64 transfers up to 40 MB/s peak.
Dual PMC slots accept conduction-cooled or air-cooled mezzanines for custom analog/digital/FPGA I/O while onboard 4 MB Flash + 1 MB socketed memory support field firmware updates. Battery-backed NVRAM/RTC preserves boot environment across power cycles in system controller or resident configurations.
Frequently Asked Questions
Q: Does the MVME2301 support hot-swapping in a VME chassis?
A: VME64 prohibits live insertion; power down the crate before installing the MVME2301. The 20 W power draw plus dual PMC loading stresses crate supplies—post-install measure all rails, verify P1/P2/VME64x seating, monitor SYSFAIL during power sequencing before PMC enumeration and VME arbitration testing.
Q: Is the MVME2301 obsolete, and what replacement paths exist?
A: Obsolete since early 2000s; MVME2300 series progressed to MVME3100 (G4) and MVME3600 (G4+). PowerPC 603-to-G4 migration requires endian/cache changes; pin-compatible VME SBCs from Wind River/VxWorks vendors need custom board support packages. Spares only for legacy VME sustainment.
