7007S55PF8

Memory IC Overview

The 7007S55PF8 is a dual-port static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 256 kilobits organized as 32K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-pin PLCC package.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two distinct ports without external arbitration logic.
• Enables expansion of data bus width to 16 bits or greater through simple dual-chip configuration.
• Incorporates on-chip hardware support for semaphore signaling to manage port access coordination.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data logging applications requiring independent host access

Memory IC Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity and moisture sensitivity handling procedures before assembly. Ensure design compatibility with existing 5V logic levels and timing requirements. Review official documentation for any pinout variations or specific handling instructions associated with the PLCC-68 form factor.

Memory IC Selection Notes

Select this component when dual-port functionality with 55ns speed is required in a 68-pin PLCC package. Consider alternatives if lower power consumption or smaller footprint is necessary. Evaluate system timing margins against the specified 55ns access time. Verify that the 4.5V to 5.5V operating range aligns with the target application power supply.

Memory IC Part Context

This part belongs to the 7007S series of dual-port SRAMs from Renesas. It offers high-speed asynchronous access for applications needing concurrent port operations. The series is designed for robust performance in demanding electronic environments.

Memory IC Replacement Considerations

The 7007S55J8 is listed as an upgrade alternative by the manufacturer. Verify pin compatibility and electrical specifications before substitution.
