7130SA25J8

Memory IC Overview

The 7130SA25J8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. 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 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. The component is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent asynchronous access from two separate ports
• Asynchronous parallel interface supporting standard read and write operations
• CMOS technology designed for low power consumption and high-speed performance

Memory IC Applications

Memory IC Procurement Notes

This component has been officially discontinued by the manufacturer. Verify availability through authorized distributors or secondary market suppliers. Confirm that replacement units meet original specifications, including pin compatibility and electrical parameters. Check for moisture sensitivity level compliance during handling. Ensure documentation matches the specific suffix J8 for the 52-PLCC package variant.

Memory IC Selection Notes

Select this part when a dual-port SRAM with 8Kb capacity and 25ns speed is required. Ensure the system design accommodates the 52-PLCC surface-mount package dimensions. Verify that the 4.5V to 5.5V supply voltage aligns with the target application's power rails. Consider the commercial temperature range limits for environmental suitability.

Memory IC Part Context

The 7130SA series belongs to Renesas' legacy portfolio of CMOS dual-port SRAMs. These devices were designed to provide flexible memory solutions for applications requiring simultaneous access from multiple processors or controllers. The 7130SA25J8 specifically represents the 8Kb density variant within this family.

Memory IC Replacement Considerations

Verify cross-references such as IDT7130SA25J. Check for equivalent dual-port SRAMs with matching 8Kb density, 25ns speed, and 52-PLCC packaging. Confirm voltage and temperature specifications match before substitution.
