7024L20J

Memory IC Overview

The Renesas Electronics Corporation 7024L20J is a dual-port static random-access memory (SRAM) device organized as 4K words by 16 bits, providing a total storage capacity of 64 kilobits. It operates asynchronously with a maximum access time of 20 nanoseconds and supports parallel interface communication. The component functions within a supply voltage range of 4.5 volts to 5.5 volts and is designed for surface-mount installation in an 84-pin Plastic Leadless Chip Carrier (PLCC) package measuring 29.31mm by 29.31mm. It maintains reliable operation across an extended industrial temperature range from -40°C to +85°C ambient temperature.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation eliminating the need for external clock synchronization
• Parallel interface supporting standard data bus connections

Memory IC Applications

• High-speed data buffering between asynchronous system components
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring wide temperature tolerance

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance for this specific part number. Confirm package integrity upon receipt, as moisture sensitivity level 3 requires strict handling protocols. Check for end-of-life notifications or discontinuation notices prior to finalizing procurement plans to ensure long-term availability.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access without arbitration overhead. Ensure the design accommodates the 4.5V to 5.5V power supply requirements and the 84-PLCC footprint constraints. Verify that the 20ns access speed meets the timing specifications of the target application interface.

Memory IC Part Context

This device belongs to the 7024L series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 7024L20JI and 7024L55JI, differing primarily in access speed and suffix designations. The series provides high-density memory solutions for complex digital systems requiring fast, independent read/write capabilities.
