7130SA70JI

Memory IC Overview

The Renesas Electronics Corporation 7130SA70JI is a 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 asynchronous parallel interface operation with a maximum access time of 70 nanoseconds and a write cycle time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) surface-mount package.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at both Port A and Port B without conflict.
• Features asynchronous logic for flexible integration into various system architectures.
• Includes dedicated chip select inputs to enable low-power standby modes.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid sequential access

Memory IC Procurement Notes

Verify the specific suffix JI against official manufacturer documentation to confirm lead-free status and RoHS compliance requirements. Confirm that the 52-PLCC package dimensions match the target PCB footprint. Check for any Product Change Notices regarding label changes or material updates before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent host and peripheral access. Ensure the 70ns speed grade meets the system timing constraints. Verify that the 4.5V to 5.5V operating voltage aligns with the design power supply rails. Consider the PLCC package availability if surface-mount assembly is mandated.

Memory IC Part Context

This part belongs to the IDT 7130SA/LA series of dual-port SRAMs. These devices are designed for high-performance applications requiring independent port access. The 7130SA variant specifically denotes the 8Kb density configuration. This series is widely used in networking and industrial control environments.

Memory IC Replacement Considerations

Consult official datasheets for pin-compatible alternatives such as the 7130LA series. Verify electrical parameter equivalence, particularly access times and voltage ranges, before substitution.
