7024L15J

Memory IC Overview

The Renesas Electronics Corporation 7024L15J 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 within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-pin Plastic Leadless Chip Carrier (PLCC) package measuring 29.31mm x 29.31mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations from two distinct ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processors
• Data acquisition system temporary storage

Memory IC Procurement Notes

Verify the exact suffix designation on the physical component, as distributors may list variants such as JG or JI which differ in packaging or temperature ratings. Confirm RoHS compliance status, as older production runs may not meet current environmental directives. Check for End-of-Life notices, as this series has been subject to discontinuation announcements. Ensure the specific lot date code aligns with moisture sensitivity level handling requirements during assembly.

Memory IC Selection Notes

Select this component when a design requires true simultaneous bidirectional data transfer without bus contention. The 15ns speed class suits applications needing fast response times but not requiring synchronous clocking. Compare against single-port alternatives if only one master accesses the memory at a time, as dual-port devices typically carry higher unit costs. Verify that the 84-PLCC footprint matches the printed circuit board layout constraints.

Memory IC Part Context

This part belongs to the IDT 7024S/L family of high-performance dual-port SRAMs originally developed by Integrated Device Technology and later acquired by Renesas. These devices were widely used in networking equipment and industrial control systems prior to the prevalence of faster synchronous memories. The 'L' suffix typically denotes low-power CMOS technology within this historical product line.

Memory IC FAQ

Can both ports access the same memory address simultaneously?

Yes, the dual-port architecture allows Port A and Port B to independently read or write to any address concurrently without conflict.

What is the power consumption characteristic of this device?

The datasheet specifies active current consumption values, which vary based on the switching frequency and load conditions during operation.
