Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pin compatibility and electrical specifications against existing designs before procurement. Check for available surplus stock or qualified substitutes if new production units are unavailable.

Memory IC Selection Notes

Select this component for applications requiring independent dual-port access to shared memory resources. Ensure the design accommodates the 52-PLCC surface mount package constraints. Verify that the operating temperature range meets the specific environmental conditions of the target application. Consider the asynchronous interface timing requirements when integrating with host processors.

Memory IC Part Context

This SRAM belongs to the 7130SA series, designed for high-performance dual-port memory applications. The 7130SA55 variant specifically denotes a 55 ns access time. The J8 suffix indicates a commercial temperature grade and PLCC package type.
