7130SA55J8/2594

Memory IC Overview

The Renesas Electronics Corporation 7130SA55J8/2594 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 of 55 nanoseconds and a write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-PLCC package measuring 19.13x19.13 mm. The component is rated for commercial temperature operation from 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two separate port interfaces
• Utilizes CMOS technology for low power consumption during active and standby modes
• Provides flexible data handling via standard parallel bus architecture

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring fast access times

Memory IC Procurement Notes

Verify the specific suffix /2594 against official manufacturer documentation to confirm if it denotes a unique packaging variant or quality certification distinct from the standard 7130SA55J8. Confirm RoHS compliance status, as standard variants are often non-compliant. Check current lifecycle status, as this series is frequently discontinued. Ensure compatibility with existing PCB footprints for the 52-PLCC package before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave data exchange without arbitration delays. Compare access speeds against other variants in the 7130SA family to match system timing requirements. Evaluate the 52-PLCC package constraints against available board space and assembly capabilities. Consider thermal management needs within the specified commercial temperature range.

Memory IC Part Context

This part belongs to the IDT/Renesas 7130SA family of high-performance dual-port SRAMs. These devices are designed for applications requiring rapid data sharing between processors. The 7130SA55J8 specifically offers 55ns speed in a leaded plastic quad flatpack package. The family shares common electrical characteristics but varies in speed grades and package types.

Memory IC Replacement Considerations

Direct substitutes include the IDT7130SA55J8 and other 7130SA55 series variants with identical pinouts and specifications. Verify that any replacement maintains the same 55ns access time and 52-PLCC footprint. Cross-reference datasheets to ensure functional equivalence in dual-port operation.
