7024S20J8

Memory IC Overview

The 7024S20J8 is a dual-port static random access memory integrated circuit manufactured by Renesas Electronics. It provides a total storage capacity of 64 kilobits, organized as 4K words by 16 bits. The device features asynchronous parallel interfaces for both ports, allowing independent read and write operations. It supports a maximum access time of 20 nanoseconds. The component operates within a supply voltage range of 4.5 volts to 5.5 volts. It is housed in an 84-lead Plastic Leadless Chip Carrier package with dimensions of 29.31mm by 29.31mm.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two distinct systems
• Asynchronous operation eliminating the need for a common clock signal between ports
• Parallel interface supporting standard data bus widths for straightforward integration

Memory IC Applications

• Data buffering in telecommunications equipment requiring high-speed temporary storage
• Cache memory implementation in industrial control systems
• Shared memory modules in embedded processing architectures

Memory IC Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted to remaining stock from authorized distributors or secondary market suppliers. Verify RoHS compliance status carefully, as older production runs may not meet current environmental directives. Confirm package integrity and moisture sensitivity handling requirements upon receipt due to potential long-term storage conditions.

Memory IC Selection Notes

Select this part when a design requires true dual-port SRAM with 16-bit word width and 20ns speed. Ensure the system power supply strictly maintains 4.5V to 5.5V to guarantee timing specifications. Compare against single-port alternatives if only one processor accesses the memory. Verify that the 84-PLCC footprint matches the existing PCB layout constraints before finalizing the bill of materials.

Memory IC Part Context

The 7024S20J8 belongs to the 7024S series of dual-port SRAMs from Renesas. This series typically includes variants with different access speeds and organization formats. The J8 suffix denotes the specific 20ns speed grade and the PLCC-84 package type. Related parts in the family include the 7024S30 and 7024S45, which offer slower access times but maintain similar pinouts and functionality.

Memory IC Replacement Considerations

Direct pin-compatible replacements are limited due to the obsolete status. Potential substitutes include other 64Kb dual-port SRAMs with 16-bit organization and 84-PLCC packages. Verify electrical compatibility regarding voltage levels and access times. Cross-reference with IDT equivalents if available, though lead times and authenticity must be rigorously audited.
