TEL MBMY-001A VME Memory Board

The TEL MBMY-001A is a VMEbus memory expansion board designed to provide non-volatile storage for industrial computing applications. This module offers EPROM (Erasable Programmable Read-Only Memory) storage organized for 32-bit data access, making it suitable for program storage, boot code, and fixed data tables in VME-based systems.

Bus Interface

The board interfaces with the VMEbus through a standard 96-pin DIN connector, supporting A24 and A32 addressing modes for flexible memory mapping. The VMEbus interface includes circuitry for address decoding, data buffering, and timing control to ensure reliable operation with various VMEbus masters. The board is designed to operate as a slave memory module, responding to read requests from CPU boards and other bus masters.
