7130SA35JI

Memory IC Overview

The Renesas Electronics Corporation 7130SA35JI 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 parallel interface access with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports a junction temperature range from -40°C to +85°C. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package measuring 19.13mm by 19.13mm.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two distinct ports for high-throughput data handling.
• Utilizes CMOS technology to provide low power consumption characteristics suitable for battery-operated systems.
• Features asynchronous operation allowing flexible timing control without reliance on a global clock signal.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be discontinued or subject to limited availability. Confirm that the 52-PLCC package dimensions align with existing PCB footprints. Ensure compliance with RoHS directives if required by the target application, noting potential variations in environmental certification across manufacturing batches.

Memory IC Selection Notes

Select this component when dual-port functionality is required to allow concurrent access from different processors or buses. The 35ns speed class suits applications needing moderate latency without the complexity of synchronous interfaces. Consider the 52-PLCC package constraints regarding board space and thermal dissipation capabilities during the design phase.

Memory IC Part Context

This device belongs to the 7130SA series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family but differs in specific capacity and pinout configurations. The series is designed for applications requiring reliable, fast, and independent data access paths in complex electronic systems.

Memory IC Replacement Considerations

Consult official manufacturer documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pin compatibility, voltage levels, and access times to avoid redesigning the host system hardware.
