7024S20J

Memory IC Overview

The Renesas Electronics Corporation 7024S20J is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kilobits, organized as 4K words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 20 nanoseconds and a write cycle time of 20 nanoseconds. It operates on a single power supply voltage ranging from 4.5 volts to 5.5 volts. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package, measuring 29.31mm by 29.31mm. It supports surface mount installation and functions within a commercial operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Provides independent read/write access to two distinct ports for simultaneous data operations.
• Supports high-speed asynchronous data transfer with a 20 nanosecond access window.
• Utilizes a standard parallel interface compatible with common microprocessor systems.

Memory IC Applications

• High-performance embedded systems requiring concurrent data handling
• Network infrastructure equipment and communication gateways
• Industrial control systems needing reliable volatile memory storage

Memory IC Procurement Notes

Verify the specific suffix designation against official documentation, as variants such as J, JI, or J8 denote differences in packaging, temperature rating, or lead finish. Confirm RoHS compliance status, as older manufacturing runs may not meet current environmental directives. Check for end-of-life notifications or discontinuance notices prior to finalizing procurement plans to ensure long-term supply chain stability.

Memory IC Selection Notes

Select this component when a system requires true dual-port architecture for non-blocking data exchange between two processors. Ensure the design accommodates the 84-lead PLCC footprint and the 4.5V to 5.5V power supply requirements. Consider the 0°C to 70°C commercial temperature range; if wider thermal operation is needed, evaluate industrial-grade alternatives within the same family.
