7007S15J

Memory IC Overview

The Renesas Electronics Corporation 7007S15J is a high-speed, dual-port static random-access memory (SRAM) device. It provides a total storage capacity of 256 kbit, organized as 32k words by 8 bits. The component features a parallel interface with an access time of 15 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 68-PLCC package. The device is designed for industrial temperature ranges, functioning between 0°C and +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.
• Asynchronous operation allowing flexible timing integration without requiring a common clock signal.
• High-speed data transfer capabilities suitable for demanding real-time processing applications.

Memory IC Applications

• Network router buffer memory management
• Industrial control system data logging
• Telecommunications equipment signal processing

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates potential non-compliance for specific variants. Confirm current manufacturing status, as the product line may be obsolete or subject to limited availability. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate pin compatibility with existing PCB footprints before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Compare against single-port alternatives if only one processor interface is needed. Consider the 15 ns access speed relative to system clock requirements. Evaluate the 68-PLCC package constraints against available board space and assembly capabilities.

Memory IC Part Context

This part belongs to the IDT/Renesas 7007 series of dual-port SRAMs. It shares architectural similarities with models like the 7007L15JG but differs in specific electrical characteristics and packaging options. The series is widely recognized for providing reliable, high-speed memory solutions in embedded systems requiring shared data buffers.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT7007S15J. Verify functional equivalence regarding pinout and electrical specifications before substitution.
