7006S55PFI

Overview

The Renesas Electronics Corporation 7006S55PFI is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 128Kb, organized as 16K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 55 ns. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from 0°C to 70°C. The component is housed in a 64-lead Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array by two separate processors or systems.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify RoHS compliance status, as documentation indicates non-compliance for this specific suffix variant. Confirm package authenticity against the 64-TQFP specification. Check for obsolescence notices or discontinuation notifications from Renesas prior to finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations without external arbitration logic. Ensure the system design accommodates the 55 ns timing constraints and the 4.5V to 5.5V power supply requirements. Verify that the 64-TQFP footprint matches the PCB layout constraints.

Part Context

This part belongs to the Renesas 7006S series of dual-port SRAMs. It shares architectural similarities with other members like the 7006S55PF but differs in packaging and suffix specifications. The series is designed for applications demanding high bandwidth and low latency between multiple masters accessing shared memory resources.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas official documentation for potential upgrades or pin-compatible alternatives if this specific package is discontinued.
