7025L35PFI

Memory IC Overview

The Renesas Electronics Corporation 7025L35PFI is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kilobits, organized as 8K words by 16 bits. The device features asynchronous parallel interface with a maximum access time of 35 nanoseconds. It operates on a single 5V power supply within the range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. It supports surface-mount installation and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two separate ports for high-throughput data handling.
• Utilizes asynchronous parallel interface architecture for straightforward integration into existing digital systems.
• Designed for industrial environments with extended operating temperature capabilities.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring rapid temporary storage

Memory IC Procurement Notes

Verify current manufacturing status as this component may be discontinued or subject to production changes. Confirm RoHS compliance requirements against specific project standards, noting that older variants often lack full environmental certification. Ensure the 100-TQFP footprint matches the target PCB layout precisely. Validate voltage levels and timing parameters against system specifications before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access without bus contention. The 35ns speed suits moderate-to-high frequency applications where cost-effective SRAM is preferred over synchronous alternatives. Consider the 100-pin package density for space-constrained designs. Verify thermal management needs for the -40°C to +85°C range if operating in extreme conditions.

Memory IC Part Context

This part belongs to the Renesas 7025 series of dual-port SRAMs, which are widely used in networking and industrial control applications. The 'L' suffix typically denotes lead-free or enhanced reliability variants compared to older 'S' series parts. These devices bridge the gap between fast register files and slower serial memories, offering byte-wide or word-wide parallel access.

Memory IC Replacement Considerations

Publicly confirmed substitute: 7025S35PF8. Note that this replacement is marked as obsolete. Verify pin compatibility and electrical characteristics carefully when transitioning between legacy and updated revisions of the 7025 family.
