7130SA55P

Memory IC Overview

The Renesas Electronics Corporation 7130SA55P 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 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports a commercial operating temperature range from 0°C to 70°C. The component is housed in a 48-pin plastic dual in-line package designed for through-hole mounting.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations on separate ports.

Memory IC Applications

• High-speed data buffering in industrial control systems
• Cache memory implementation in embedded processing units
• Data storage in telecommunications equipment

Memory IC Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status prior to integration, as this variant may not meet current environmental directives. Validate lead-free availability if required by assembly processes. Ensure sourcing channels provide traceability for discontinued components.

Memory IC Selection Notes

Select this component when a parallel interface with dual-port capability is required for 8-kilobit memory applications. The 55-nanosecond speed class suits moderate-frequency asynchronous systems. Consider the 48-pin DIP form factor for legacy board designs requiring through-hole technology. Evaluate power consumption limits against the specified 4.5V to 5.5V supply range.

Memory IC Part Context

This part belongs to the 7130SA series of CMOS dual-port SRAMs manufactured by Renesas Electronics. The series offers various access speeds and package options to support diverse memory requirements in computing and communication hardware. The 7130SA55P specifically targets applications needing reliable, fast parallel data access in a standard DIP footprint.

Memory IC Replacement Considerations

Consult official substitution guides for compatible parts within the same family or equivalent offerings from other manufacturers. Verify pin-to-pin compatibility and electrical parameter alignment before replacement.
