The MM-6326/32M is a high-speed VME/VSB memory module delivering 32 MB of capacity with dual-bus support for demanding embedded systems. Engineered for data acquisition, signal processing, and memory-intensive real-time operations, this module combines fast access times with flexible block transfer capabilities to exceed 30 Mbytes/sec throughput. It integrates byte-level parity checking and diagnostic control registers to ensure data integrity in mission-critical environments.
