7024S15J

Memory IC Overview

The Renesas Electronics Corporation 7024S15J 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 15 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package, measuring 29.31mm by 29.31mm. It supports surface mount installation and functions within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two separate ports for high-throughput data handling.
• Includes on-chip hardware logic for semaphore signaling to manage arbitration between the two ports.
• Features automatic power-down control via Chip Enable inputs to minimize standby power consumption.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network communication devices

Memory IC Procurement Notes

Verify component authenticity due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for valid date codes and physical integrity upon receipt. Ensure replacement components maintain pin compatibility and electrical specifications for existing designs.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. The 15ns speed suits applications needing rapid data exchange. Consider the 84-PLCC package constraints for PCB layout. Evaluate alternative packages if lead-free manufacturing is mandatory.

Memory IC Part Context

This part belongs to the 7024S series of dual-port SRAMs from Renesas Electronics. It shares architectural similarities with other variants like the 7024S25J but offers faster access times. The series is designed for applications requiring independent port access without external arbitration logic.

Memory IC Replacement Considerations

The IDT7024S15J is a confirmed substitute part number for this component. Verify that the substitute maintains identical pinout and electrical characteristics before integration into existing circuits.
