7130SA70J

Memory IC Overview

The Renesas Electronics Corporation 7130SA70J is a dual-port static random-access memory (SRAM) integrated circuit. It features an asynchronous parallel interface with a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device supports a maximum access time of 70 nanoseconds and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation. The component is rated for commercial operating temperatures ranging from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for straightforward integration into standard digital systems
• CMOS technology providing low power consumption characteristics

Memory IC Applications

• Data buffering in high-speed communication interfaces
• Cache memory implementation in embedded processing systems
• Temporary data storage in industrial control logic circuits

Memory IC Procurement Notes

This component has reached end-of-life status and is no longer manufactured by Renesas Electronics. Procurement is restricted to existing surplus stock or secondary market distributors. Verify RoHS compliance status, as the device does not meet current environmental directives. Confirm moisture sensitivity level handling requirements during storage and assembly to prevent package damage.

Memory IC Selection Notes

Engineers replacing this obsolete part should evaluate alternative dual-port SRAMs with compatible pinouts and electrical specifications. Consider devices offering extended temperature ranges if operating conditions exceed commercial limits. Ensure that any substitute maintains the required 70ns access speed and 52-lead PLCC form factor to fit existing board layouts without redesign.

Memory IC Part Context

The 7130SA series represents a family of CMOS dual-port SRAMs produced by Integrated Device Technology, now part of Renesas Electronics. These components were widely used in applications requiring high-speed data sharing between two processors or buses. The 7130SA70J specifically denotes the 70-nanosecond speed grade within the 8K-bit density segment of this legacy product line.

Memory IC Replacement Considerations

Direct pin-compatible replacements are limited due to the discontinued status. Review datasheets for equivalent parts such as the IDT7130SA series variants or modern equivalents from other manufacturers that support 52-PLCC packaging and similar timing parameters.
