7024S35J

Memory IC Overview

The Renesas Electronics Corporation 7024S35J is a dual-port static random-access memory (SRAM) device with a storage capacity of 64 kbit, organized as 4K x 16. It features an asynchronous parallel interface and a typical access time of 35 ns. The component operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. It is housed in an 84-pin PLCC package designed for surface mount technology. The device supports standard SDR memory types and is rated for commercial operating temperatures between 0°C and +70°C.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent read/write operations from either port without bus contention.
• Integrated hardware support for semaphore signaling and interrupt flags to facilitate efficient data synchronization between processors.
• On-chip arbitration logic manages concurrent access requests, ensuring reliable data integrity during multi-master operations.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency packet handling.
• Cache memory implementation in embedded systems where independent processor access is critical.
• Real-time signal processing applications involving complex data exchange between multiple control units.

Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for active discontinuation notices or end-of-life notifications prior to finalizing procurement plans to ensure long-term supply stability.

Memory IC Selection Notes

Select this component when a true dual-port SRAM solution is required for applications needing simultaneous access from two distinct masters. Ensure the design accommodates the 84-PLCC package constraints and the 35 ns access time requirements. Verify that the system power supply strictly adheres to the 4.5 V to 5.5 V operating range to maintain signal integrity and prevent functional errors.

Memory IC Part Context

This part belongs to the Renesas 7024/7025 series of dual-port SRAMs, which are widely used in industrial and communication systems. The 'S' suffix typically denotes standard speed grades, while the 'J' indicates the plastic leaded chip carrier package. These devices are engineered to replace legacy discrete logic solutions by integrating arbitration and control functions directly onto the silicon die.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers for the 7024S35J were not identified in the provided source material. Consult official Renesas cross-reference guides for potential alternatives such as the 7024L series if lower power consumption is required, ensuring all electrical and mechanical parameters match.
