7024S35J8

Memory IC Overview

The Renesas Electronics Corporation 7024S35J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 4K words by 16 bits. The device features asynchronous parallel interface operation with a maximum access time of 35 nanoseconds. It operates on a single 5V power supply ranging from 4.5V to 5.5V. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package and supports surface mount installation. It functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent read and write operations for both ports without conflict.
• Asynchronous operation allows flexible timing control from either port without requiring a common clock signal.
• On-chip hardware support for semaphore signaling facilitates efficient data synchronization between the two ports.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring simultaneous multi-port access

Memory IC Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package availability since standard packaging may vary. Check for end-of-life notifications or discontinuation notices prior to finalizing procurement plans. Ensure voltage levels match system requirements strictly within the specified 4.5V to 5.5V range.

Memory IC Selection Notes

Select this component when true dual-port functionality is required for concurrent data handling. The 35ns access speed suits moderate-to-high frequency applications. Consider the 84-PLCC package constraints for board layout. Verify that the 5V logic level compatibility aligns with the target system's I/O standards.

Memory IC Part Context

This part belongs to the 7024S series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 7024S20 and 7024S45, differing primarily in access speed and package options. The series is designed for applications needing high-bandwidth memory sharing between processors or peripherals.
