7130SA55J8

Memory IC Overview

The Renesas Electronics Corporation 7130SA55J8 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 parallel interface access with a maximum access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-lead Plastic Leadless Chip Carrier (PLCC) package measuring 19.13x19.13 millimeters. The component is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two separate ports.

Memory IC Applications

• High-speed data buffering in embedded systems.

Memory IC Procurement Notes

Verify the specific suffix J8 against official documentation to confirm the 52-PLCC package configuration and commercial temperature rating. Confirm RoHS compliance status, as this variant may not meet current environmental standards. Check for active production status or obsolescence notifications prior to procurement planning.

Memory IC Selection Notes

Select this component when a compact 8Kb dual-port SRAM solution is required for applications needing concurrent read/write operations. Ensure the design accommodates the 52-PLCC footprint and 4.5V to 5.5V power requirements. Consider thermal management for the 0°C to 70°C operating range.

Memory IC Part Context

This part belongs to the 7130SA series of high-speed CMOS dual-port SRAMs manufactured by Renesas Electronics. The series is designed for applications requiring fast, independent access to shared memory resources without complex arbitration logic.

Memory IC Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the same family, such as variants with different access speeds or temperature ranges. Verify package compatibility before substitution.
