7008L20JI8

Memory IC Overview

The Renesas Electronics Corporation 7008L20JI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 512 kilobits, organized as 64K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time and write cycle time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing units
• Data acquisition systems requiring rapid temporary storage

Memory IC Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations such as JGI8 or PFGI8 indicate specific packaging or environmental compliance differences. Confirm current availability status, as this series may be subject to discontinuation notices. Ensure compatibility with existing board layouts for the 84-PLCC footprint during procurement planning.

Memory IC Selection Notes

Select this component when a system requires independent dual-port memory access for concurrent processor interactions. The 20ns speed class suits applications needing fast asynchronous data handling. Verify that the 4.5V to 5.5V supply requirement aligns with the target system's power rails and that the PLCC package fits the mechanical constraints.

Memory IC Part Context

This part belongs to the IDT 7008L20 family of dual-port SRAMs manufactured by Renesas Electronics. These devices are designed for high-performance applications where two masters need to access the same memory space simultaneously without bus contention. The family typically offers various pin counts and speeds to match different bandwidth requirements.

Memory IC Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully if considering alternative manufacturers.
