70825S35PFGI

Memory IC Overview

The 70825S35PFGI is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 128 kilobits, organized as 8K words by 16 bits. The device features asynchronous parallel interfaces for both ports, supporting independent read and write operations. Key electrical parameters include a maximum access time of 35 nanoseconds and a write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V. The component is housed in an 80-lead Thin Quad Flat Package (TQFP) with dimensions of 14mm x 14mm, suitable for surface-mount technology applications.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to shared memory locations from two distinct ports.
• Asynchronous operation allowing flexible timing control for both read and write cycles without external clock synchronization.
• Parallel interface design providing direct connection capabilities for high-speed data transfer between the memory and host systems.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency memory access.
• Network switch and router architectures utilizing dual-port RAM for packet processing and traffic management.
• Industrial automation controllers where simultaneous data logging and retrieval are required for real-time monitoring.

Memory IC Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations may indicate differences in temperature grades or packaging formats. Confirm current availability status, as this component series may be subject to discontinuation notices. Ensure that the procurement channel provides valid traceability and authenticity guarantees for obsolete electronic components.

Memory IC Selection Notes

Select this component when a system requires true dual-port memory functionality with asynchronous control signals. The 16-bit word width is suitable for data buses requiring wider throughput compared to 8-bit alternatives. Verify that the operating voltage requirements align with the 4.5V to 5.5V specification before integration into the target circuit design.

Memory IC Part Context

This part belongs to the IDT 70825 family of dual-port SRAMs, which has been integrated into the Renesas Electronics product portfolio following corporate acquisitions. The 70825 series is characterized by its high-speed performance and reliability in demanding embedded environments. This specific model represents a standard commercial grade variant within the broader dual-port memory lineup.

Memory IC Replacement Considerations

Direct replacements should be sought from the IDT 70825L20 or 70825S25 series, provided the access speed meets system requirements. Verify pin compatibility and voltage levels before substitution. Consult official Renesas obsolescence notices for recommended upgrade paths if the 70825S35PFGI is no longer in production.
