7005S55PFI8

Overview

The Renesas Electronics Corporation 7005S55PFI8 is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 64-pin Thin Quad Flat Package measuring 14x14 millimeters. The component is designed for commercial temperature ranges spanning from 0°C to 70°C.

Feature Summary

• Provides independent read/write ports for simultaneous data access without bus contention
• Supports asynchronous operation with fast 55 nanosecond access times
• Integrates standard TTL-compatible logic levels for direct interfacing

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications requiring concurrent port access

Procurement Notes

Verify the exact suffix configuration against official datasheets, as package variations exist within the series. Confirm RoHS compliance status, as specific variants may not meet current environmental directives. Check for discontinuation notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when dual-port architecture is required for non-blocking data transfer between two masters. Ensure the system voltage aligns with the specified 4.5V to 5.5V operating range. Consider the 64-TQFP footprint constraints during PCB layout design to ensure proper thermal dissipation and mechanical stability.

Part Context

This part belongs to the Renesas 7005 family of dual-port SRAMs. It shares architectural similarities with other members like the 7005S25 and 7005L series, differing primarily in speed grades and temperature specifications. The 7005S55 variant targets general-purpose commercial applications requiring moderate speed performance.
