7024L20JI

Memory IC Overview

The Renesas 7024L20JI is a dual-port static random-access memory (SRAM) integrated circuit with a storage capacity of 64Kb, organized as 4K words by 16 bits. It features asynchronous parallel interface operation with a maximum access time and write cycle time of 20 ns. The device operates on a single 5V power supply ranging from 4.5V to 5.5V. It is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package measuring 29.31x29.31 mm. The component supports surface mount installation and functions within a commercial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous parallel interface for flexible system integration
• High-speed 20 ns access time for rapid data retrieval

Memory IC Applications

• Embedded systems requiring shared memory resources
• Industrial control units needing fast data buffering
• Telecommunications equipment utilizing high-speed memory interfaces

Memory IC Procurement Notes

Verify the current lifecycle status before procurement, as this component is listed as obsolete or end-of-life. Confirm that the 84-PLCC package dimensions match your PCB footprint requirements. Ensure voltage levels align with the specified 4.5V to 5.5V operating range. Check for RoHS compliance limitations if environmental regulations apply to your specific deployment context.

Memory IC Selection Notes

Select this component when a dual-port SRAM solution is required for applications needing concurrent read/write operations from separate processors. The 20 ns speed class suits moderate-to-high frequency asynchronous buses. Consider the 84-PLCC package constraints regarding board space and soldering capabilities compared to smaller surface-mount alternatives.

Memory IC Part Context

This part belongs to the Renesas 7024L series of dual-port SRAMs. It shares architectural similarities with other variants like the 7024L45J and 7024L55JI, differing primarily in access speed and temperature ratings. The series provides versatile memory solutions for complex embedded architectures requiring non-volatile-like persistence during active operation without clock synchronization.
