Product Introduction

Motorola MVME162-262 provides MC68040 processing at 25 MHz on the VMEbus with 16 MB DRAM, Ethernet connectivity, four serial ports, and two IndustryPack slots for high-performance embedded applications. VMEchip2 ASIC supports full A32/D32:D64 master/slave operation including system controller capability with peak D64/MBLT transfers to 40 MB/s.

Dual IP slots enable custom I/O expansion while onboard networking and serial interfaces handle standard communications requirements. Battery-backed SRAM/NVRAM and 1 MB Flash with embedded diagnostics support field serviceability and firmware updates without VMEbus host dependency.

Frequently Asked Questions

Q: Does the MVME162-262 support hot-swapping in a VME chassis?
A: VMEbus prohibits live module changes; power down the complete crate before installing the MVME162-262. The 4.5 A max @ 5 VDC loading demands crate power verification—measure +5/+12/−12 V rails post-install, confirm P1/P2 connector integrity, monitor SYSFAIL during power sequencing before VME arbitration.

Q: Is the MVME162-262 obsolete, and what are replacement paths?
A: Obsolete since early 2000s; MVME162 series progressed to PowerPC MVME2400/2600/3600 with PMC expansion replacing IP slots. MC68040-to-PPC porting requires cache coherency and MMU code changes; compatible VME SBCs from VxWorks vendors need custom board support packages for legacy sustainment.

Q: Will I lose application code or configuration when replacing the MVME162-262?
A: Flash/EPROM and SRAM contents persist through battery backup; DRAM clears on power loss. Document IP slot assignments, VME address decoders, and Ethernet PHY configuration—extract 1 MB Flash image via BDM, photograph J11-J24 jumpers, verify network settings before field board swap.
