7005L35PFG8

Overview

The Renesas Electronics Corporation 7005L35PFG8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 64 kilobits. The device features an 8K x 8 organization and utilizes a parallel interface for data transfer. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum access time of 35 nanoseconds. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. It is designed for surface-mount installation and functions reliably within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Supports simultaneous independent reads and writes from two separate ports without conflict
• Includes on-chip hardware logic for semaphore signaling and port arbitration
• Features automatic power-down control via chip enable inputs for low standby current
• Provides interrupt flag capabilities for efficient host processor monitoring

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data logging applications requiring non-volatile backup support
• Master/slave configurations in 16-bit or wider data bus architectures

Procurement Notes

Verify the specific package suffix against official documentation, as the provided model number may indicate a variant not explicitly listed in standard public catalogs. Confirm RoHS compliance status, as older 7005 series variants often lack this certification. Ensure the supplier provides valid traceability documents for this discontinued component type.

Selection Notes

Select this component when true dual-port functionality is required for concurrent data access by multiple processors. Consider the 35ns access speed and 64-pin TQFP footprint for space-constrained designs. Evaluate the need for hardware semaphore support if complex synchronization between ports is necessary for the target application architecture.

Part Context

This part belongs to the Renesas 7005 family of dual-port SRAMs, which are designed for standalone or master/slave operation. The family offers various access speeds and packaging options to suit different performance and physical layout requirements. These devices are widely used in embedded systems requiring high-reliability memory interfaces.

Replacement Considerations

Publicly confirmed substitute part numbers include the 7005L15PFG8. Verify pin compatibility and electrical specifications before substitution.
