I. Product Positioning

MVME167‑035B is a 6U VME single-height SBC from Motorola/Emerson. It is the enhanced version (B version) of the MVME167 series with 33MHz, mid-to-high configuration, and 64MB ECC memory for industrial applications.

Core: 33MHz MC68040 + 64MB ECC DRAM + high reliability / strong anti-interference / long-term operation.

It is fully compatible and directly interchangeable with the entire series (A/B) of 031/032/033/034 (in terms of pins, mechanics, and interfaces).

Positioning: 33MHz, 64MB ECC, high-reliability industrial control, data-intensive, long-term unmanned VME system.
