7005S15PFI

Overview

The Renesas Electronics Corporation 7005S15PFI is a static random access memory device featuring an 8K x 8 organization and 64 kbit storage capacity. It operates with a 25 ns access time and supports parallel asynchronous interfaces. The component functions within a 4.5 V to 5.5 V supply voltage range, drawing a maximum current of 250 mA. Designed for surface mount installation, it utilizes a TQFP-64 package. The unit supports single data rate operations and maintains functionality across a commercial temperature range from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling simultaneous independent access to memory cells
• Integrated hardware semaphore signaling for port arbitration
• Asynchronous operation supporting master/slave configurations

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller applications
• Data logging and temporary storage in industrial controllers

Procurement Notes

Verify the specific suffix PFI against official datasheets to confirm the TQFP-64 package type and commercial temperature grade. Confirm RoHS compliance status as historical records indicate non-compliance for some variants in this series. Check moisture sensitivity level requirements for handling during assembly processes.

Selection Notes

Select this component when dual-port capability is required for concurrent read/write operations without external arbitration logic. Ensure the design accommodates the 5V TTL-compatible interface levels. Verify that the TQFP-64 footprint matches the PCB layout constraints and thermal management requirements for the target operating environment.

Part Context

This part belongs to the Renesas 7005L/S series of dual-port SRAMs. These devices are designed for applications requiring high-speed data exchange between two processors or systems. The series offers various speed grades and packaging options to suit different performance and form factor needs.

Replacement Considerations

Consult official substitution guides for equivalent dual-port SRAMs with matching 8K x 8 density and TQFP-64 packages. Verify pin compatibility and electrical specifications before replacement.
