Overview
The AM79C961AVC is a high-performance VMEbus interface controller manufactured by Rochester Electronics. It serves as a bridge between the VMEbus and peripheral devices, supporting standard VMEbus protocols for data transfer. The device integrates necessary logic to manage bus arbitration and addressing within VME systems. It is designed for robust operation in industrial and embedded applications requiring reliable VMEbus connectivity. The component facilitates efficient communication between the system backplane and attached peripherals.
Feature Summary
- Supports standard VMEbus protocol operations
- Integrates bus arbitration logic
- Provides peripheral interface bridging
Applications
- Industrial control systems
- Embedded computing platforms
- VMEbus-based instrumentation
Procurement Notes
Verify the specific suffix 'AVC' against official datasheets to confirm package type and temperature range. Ensure the component matches the required pinout and electrical specifications for the target design. Confirm RoHS status and manufacturing origin with the supplier. Request lot traceability if required for quality assurance standards.
Selection Notes
Select this component when a dedicated VMEbus interface controller is required for legacy or specialized VME systems. Compare pin compatibility and voltage levels with existing designs. Consider thermal requirements and package constraints during integration. Verify that the controller's arbitration features meet the system's bus timing needs.
Part Context
Rochester Electronics specializes in sustaining obsolete semiconductor products. The AM79C961AVC is part of their portfolio of licensed and tested components. This ensures continued availability for systems that cannot be easily redesigned. The company maintains inventory and wafer banks to support long-term production needs.
Replacement Considerations
Check for direct pin-to-pin replacements from other manufacturers. Verify functional equivalence with original Cypress/AMD datasheets. Ensure any substitute supports the same VMEbus speed and arbitration modes.
