70825L35PFGI8

Memory IC Overview

The Renesas Electronics Corporation 70825L35PFGI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128K bits, organized as 8K words by 16 bits. The device features asynchronous parallel interface operation with an access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors or systems
• Asynchronous operation eliminating the need for external clock synchronization
• Parallel data interface supporting standard high-speed data transfer protocols

Memory IC Applications

• Network router buffer memory management
• Telecommunications switching equipment data buffering
• Industrial control system data logging

Memory IC Procurement Notes

Verify RoHS compliance status as older variants may not meet current environmental standards. Confirm package marking accuracy against datasheet specifications. Check for moisture sensitivity level handling requirements during assembly. Validate supplier authorization to ensure genuine components. Review product change notices for any recent manufacturing updates.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider the 100-TQFP footprint for PCB layout compatibility. Verify thermal requirements against the specified industrial temperature range. Compare performance metrics with newer generation alternatives if available.

Memory IC Part Context

This part belongs to the Renesas 70825 series of dual-port SRAM devices. It shares architectural similarities with other members like the IDT70825L20PFI but differs in speed grade. The series is designed for applications requiring high-speed data sharing between multiple masters without bus contention.

Memory IC Replacement Considerations

The 7025L20PFGI8 is listed as an upgrade alternative. Verify pinout compatibility and electrical parameter alignment before substitution. Confirm that the faster access time of the replacement does not require timing adjustments in the host system.
