Product Introduction
Motorola MVME162-14 provides MC68040 processing at 25 MHz on the VMEbus with 8 MB DRAM, Ethernet, SCSI, four serial ports, and four IndustryPack expansion slots for high-end embedded systems. It supports full A32/D32:D64 VME master/slave operation including system controller functions through dedicated VMEchip2 and MCchip ASICs.
Target applications include multiprocessor VME signal processing, telecom switches, and radar controllers where IP modules add custom analog/digital I/O. Battery-backed SRAM/RTC preserve boot parameters; Flash/EPROM options support field firmware updates without VMEbus dependency.
Frequently Asked Questions
Q: Does the MVME162-14 support hot-swapping in a VME chassis?
A: VMEbus standards prohibit live module insertion; power down the crate before installing the MVME162-14. The 3.8 A @ 5 VDC maximum significantly loads crate supplies—post-install, measure all three rails, verify P1/P2 pin tension, and monitor SYSFAIL/ACFAIL lines before multiprocessor arbitration testing.
Q: Is the MVME162-14 obsolete, and what are the replacement options?
A: Obsolete since early 2000s; MVME162 series progressed to PowerPC MVME2400/2600/3600 with PMC expansion replacing IP slots. 68040-to-PPC code migration requires MMU/cache changes; pin-compatible boards from Concurrent/VxWorks vendors exist but need custom BSP ports. Legacy VME support only through spares.
Q: Will I lose VME application code or configuration when replacing the board?
A: EPROM/Flash and SRAM contents persist through battery backup; DRAM clears on power loss. Critical risk: undocumented IP module assignments and VME address decodes—backup Flash with BDM tool, photograph J11-J24 jumper positions, verify SCSI termination before swap to avoid bus contention.
