7005L20PFGI8

Overview

The Renesas Electronics Corporation 7005L20PFGI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. The component is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Supports simultaneous independent read and write operations on both ports without bus contention.
• Integrates hardware semaphore logic to manage data integrity during concurrent access.
• Provides interrupt generation capabilities to signal status changes between processors.

Applications

• Multiprocessor systems requiring shared memory resources
• High-speed data buffering in communication equipment
• Real-time control applications in industrial automation

Procurement Notes

Verify the specific suffix configuration against current manufacturer documentation, as package and environmental compliance variations may exist within the product family. Confirm that the lead-free designation aligns with project requirements. Check for official end-of-life notices or production change notifications prior to finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when a system requires true simultaneous bidirectional data transfer between two independent masters. The 20ns access speed suits high-frequency processing tasks. Ensure the design accommodates the 100-pin TQFP footprint and the specified 4.5V to 5.5V power supply constraints. Verify thermal management capabilities for the -40°C to +85°C operational envelope.

Part Context

This part belongs to the Renesas 7005 series of dual-port SRAMs, designed for applications needing fast, conflict-free memory sharing. The 7005L20 variant specifically denotes the 20ns speed grade within the 64Kb density class. It serves as a bridge between disparate processing units in complex embedded architectures.

Replacement Considerations

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