7025S55J8

Memory IC Overview

The Renesas Electronics Corporation 7025S55J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kbit, organized as 8k words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in an 84-pin PLCC package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems.

Memory IC Applications

• High-speed data buffering in telecommunications equipment.

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against specific project standards, as the source indicates non-compliance. Validate package integrity upon receipt, ensuring no physical damage to the 84-PLCC leads. Review official datasheets for updated handling guidelines regarding moisture sensitivity levels before assembly.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations between separate system buses. The 55 ns access speed suits moderate-frequency applications where cost-effective SRAM is preferred over faster alternatives. Ensure the design accommodates the 84-PLCC footprint and standard 5V logic levels without requiring level shifting.

Memory IC Part Context

This part belongs to the 7025S55 series of dual-port SRAMs manufactured by Renesas Electronics. It serves as a legacy component within their memory portfolio, previously distributed under IDT branding. The device represents a standard solution for embedded systems requiring reliable, volatile memory with independent port access capabilities.

Memory IC Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify pin compatibility and electrical specifications before integrating any alternative components into existing designs.
