7130SA55C

Memory IC Overview

The 7130SA55C is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It provides a storage capacity of 8 kbit, organized as 1K x 8 bits. The device 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 component is housed in a CDIP-SB-48 package and is designed for commercial temperature operation between 0°C and +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate systems or processors.
• Asynchronous parallel interface supporting standard logic levels for straightforward integration.
• CMOS technology providing high-speed data access capabilities.

Memory IC Applications

• Data buffering in telecommunications equipment
• Cache memory implementation in embedded control systems
• High-speed data logging applications

Memory IC Procurement Notes

Verify the end-of-life status before procurement planning, as this component may be discontinued. Confirm RoHS compliance requirements against project specifications, as indicated non-compliance in available records. Ensure the CDIP-SB-48 package type matches the target PCB footprint and assembly capabilities. Validate that the 5V operating voltage aligns with the system power design.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations without bus contention. The 55 ns access speed suits moderate-to-high frequency asynchronous applications. Consider the through-hole CDIP-SB-48 package if surface-mount options are unavailable or if mechanical robustness is prioritized. Verify compatibility with existing 5V logic families.

Memory IC Part Context

This part belongs to the 7130SA series of dual-port SRAMs from Renesas Electronics. It shares architectural similarities with other members like the 7130SA55JI8 but differs in packaging and temperature rating. The series is characterized by CMOS technology and parallel interfaces, serving legacy industrial and communication markets requiring reliable dual-port memory solutions.
