7130SA25JI

Memory IC Overview

The Renesas Electronics Corporation 7130SA25JI is an asynchronous 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 a parallel interface with a maximum access time and write cycle time of 25 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 measuring 19.13mm x 19.13mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations from two separate ports.

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Real-time data logging in industrial control equipment

Memory IC Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations exist. Confirm RoHS compliance status, as many units in this series are non-compliant. Check current lifecycle status, as this part may be discontinued or subject to last-time buy restrictions. Ensure compatibility with existing PCB footprints for the 52-PLCC package.

Memory IC Selection Notes

Select this component when a compact 8Kb dual-port SRAM solution is required for asynchronous parallel applications. Consider the 25ns speed grade for moderate performance needs. Evaluate the 52-PLCC package suitability for automated assembly processes. Compare against other members of the 7130SA family for alternative speed grades or temperature ranges if requirements differ.

Memory IC Part Context

This component belongs to the Renesas 7130SA/7140SA series of CMOS dual-port SRAMs. These devices are designed for high-reliability applications requiring fast, independent port access. The series typically offers various speed grades and organizational configurations to support diverse system architectures in networking and industrial sectors.

Memory IC Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the same series. Verify electrical specifications match before substitution. Note that suffixes indicate specific speed grades or packaging types.
