7005L15PFG

Overview

The Renesas Electronics Corporation 7005L15PFG is a high-speed, asynchronous dual-port static random access memory (SRAM) with a storage capacity of 64 kbit. It features an organization of 8K x 8 bits and supports parallel interface communication. The device offers a maximum access time of 15 ns and operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 64-pin TQFP surface-mount package and is designed for industrial temperature ranges.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent reads from both ports without conflict
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity
• Automatic power-down feature controlled by chip enable signals for low standby power consumption
• TTL-compatible single 5V power supply operation ensuring compatibility with standard logic families

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port RAM configurations for 16-bit or wider word systems
• High-speed data buffering in embedded processing applications
• Battery backup operations requiring 2V data retention capabilities

Procurement Notes

Verify the specific suffix PFG against the official datasheet to confirm the 64-TQFP package and commercial temperature range specifications. Ensure that the ordering information matches the exact part number variant required for your design, as suffixes may indicate different packaging or environmental ratings. Cross-reference with the manufacturer's current product status to confirm availability and lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component when simultaneous independent access to shared memory locations is required without external arbitration overhead. The 15 ns access speed suits high-performance digital signal processing and real-time control applications. Consider the 64-pin TQFP footprint for PCB layout constraints and verify that the 5V logic levels align with the system's I/O requirements. Evaluate the interrupt flag functionality if complex handshaking protocols are needed between master and slave processors.

Part Context

This device belongs to the Renesas 7005 series of dual-port SRAMs, which are designed for versatile memory sharing in multi-processor environments. The series provides various access speeds and package options to accommodate different performance and form factor needs. As a legacy component, it represents established technology for reliable, high-speed memory interfacing in industrial and consumer electronics.

Replacement Considerations
