7025L35PFI8

Memory IC Overview

The Renesas Electronics Corporation 7025L35PFI8 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 operation with a maximum access time of 35 nanoseconds. It operates on a single 4.5V to 5.5V power supply 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) with a 14x14 mm footprint.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent read/write operations from two separate ports.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage concurrent access conflicts.
• Interrupt flag functionality allowing one port to signal status changes or events to the other port.
• Automatic power-down mode controlled by chip enable signals to minimize standby power consumption.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring non-volatile retention via battery backup
• Industrial control systems operating within extended temperature ranges

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as older variants may not meet current environmental directives. Check for moisture sensitivity level handling requirements during assembly. Ensure package compatibility with existing PCB footprints. Validate lead times as availability may vary based on production lifecycle status.

Memory IC Selection Notes

Select this component when dual-port isolation is required for concurrent processor access. Consider the 35ns access speed against system timing constraints. Evaluate the 100-pin TQFP package for surface-mount assembly capabilities. Compare power consumption characteristics against alternative SRAM families. Verify temperature range suitability for the intended operational environment.

Memory IC Part Context
