7005L17PF8

Overview

The Renesas Electronics Corporation 7005L17PF8 is an asynchronous dual-port static random-access memory (SRAM) with a density of 64 kbit, organized as 8k x 8. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V and features a maximum access time of 17 ns. The component utilizes a 64-pin Thin Quad Flat Package (TQFP) with a 0.8 mm pitch and supports surface-mount installation. Designed for industrial applications, it functions within a temperature range of 0°C to +70°C.

Feature Summary

• True dual-ported memory cells enable simultaneous independent reads from the same memory location by both ports.
• On-chip hardware logic provides automatic port arbitration and semaphore signaling for master/slave configurations.
• Integrated interrupt flag functionality allows efficient status monitoring between connected processors.
• Automatic power-down mode controlled by chip select signals minimizes standby power consumption.

Applications

• High-speed data buffering in telecommunications equipment
• Shared memory interfaces in digital signal processing systems
• Master/slave processor communication architectures
• Industrial control system data logging

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Ensure compatibility with existing PCB footprints and thermal management designs. Review datasheet specifications for electrical limits and operating conditions to validate system integration.

Selection Notes

Select this component for applications requiring high-speed concurrent access to shared memory resources. The 17 ns access speed suits moderate-to-high frequency asynchronous interfaces. Verify that the 64-pin TQFP package aligns with manufacturing capabilities and board space constraints. Consider the 5V TTL-compatible I/O levels for direct interfacing with standard logic families.

Part Context

The 7005 series represents a family of high-speed dual-port SRAMs designed for flexible system integration. This specific model belongs to the L-series, indicating commercial temperature range operation. It serves as a versatile memory solution for expanding bus widths or facilitating rapid data exchange between multiple controllers in embedded environments.

Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when evaluating alternatives to ensure functional compatibility without redesigning the host circuitry.
