7130LA55C

Memory IC Overview

The Renesas Electronics Corporation 7130LA55C is an asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 8 kbit, organized as 1K x 8 bits. The component features a parallel interface with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power supply current of 110 mA. The device is designed for commercial temperature operation, functioning between 0°C and +70°C. It is housed in a CDIP-SB-48 package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous parallel interface for straightforward system integration
• CMOS technology ensuring low power consumption during operation

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded controllers
• Data storage in industrial automation equipment

Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status as historical records may vary. Check for end-of-life notifications or discontinuance notices prior to procurement planning. Ensure the supplier provides valid traceability documents for the component batch.

Memory IC Selection Notes

Select this component when a small-capacity, high-reliability dual-port memory solution is required for commercial-grade applications. Compare the 55 ns access speed against system timing requirements. Evaluate the CDIP-SB-48 package constraints against available PCB real estate. Consider the 4.5 V to 5.5 V operating range for power supply design compatibility.

Memory IC Part Context

The 7130LA55C belongs to the Renesas 7130SA/LA series of dual-port SRAMs. This family is characterized by its CMOS construction and independent port control. The 'LA' suffix typically denotes lead-free and RoHS-compliant variants compared to older 'SA' versions. These devices are engineered for applications requiring concurrent read/write operations from separate masters.

Memory IC Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully before replacing.
