7130SA70JI8

Memory IC Overview

The Renesas Electronics Corporation 7130SA70JI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-lead Plastic Leadless Chip Carrier (PLCC) package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate ports
• Asynchronous operation allowing flexible timing control for read and write cycles
• Parallel data interface supporting standard digital logic connections

Memory IC Applications

• High-speed data buffering in industrial control systems
• Communication equipment requiring low-latency memory access
• Embedded systems needing independent port arbitration

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity and moisture sensitivity handling prior to assembly. Check for RoHS compliance variations across manufacturing lots. Validate pin compatibility with existing PCB footprints before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data processing. Ensure system voltage aligns with the specified 4.5V to 5.5V range. Consider the 52-PLCC package constraints for board layout. Evaluate thermal requirements against the commercial temperature operating limits.

Memory IC Part Context

This part belongs to the 7130SA series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 7133SA and 7134SA families but differs in density and pin configuration. The series targets applications requiring high-speed, non-volatile-like performance without refresh cycles.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-references with IDT equivalents if applicable, ensuring electrical and mechanical specifications match exactly.
