7025L25PFG

Memory IC Overview

The Renesas Electronics Corporation 7025L25PFG is an asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 128 kbit, organized as 8K words by 16 bits per word. The component supports parallel interface communication with a maximum access time of 25 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The device is housed in a 100-pin Thin Quad Flat Package (TQFP) suitable for surface-mount technology applications.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent read and write operations from two separate ports without conflict.
• Integrated hardware semaphore signaling logic to facilitate automatic port arbitration and data integrity management between processors.
• Supports multiplexed bus compatibility through separate upper-byte and lower-byte control signals for flexible system integration.

Memory IC Applications

• High-speed data buffering in multi-processor computer systems
• Real-time signal processing architectures requiring low-latency memory access
• Master/slave dual-port RAM configurations for expanded data bus systems

Memory IC Procurement Notes

Verify the specific suffix PFG against official Renesas documentation to confirm package type and temperature rating. Confirm RoHS compliance status as legacy variants may differ. Check current production lifecycle status, as older SRAM models are frequently subject to discontinuation notices. Ensure design-in compatibility with existing PCB footprints for 100-pin TQFP packages before finalizing procurement plans.

Memory IC Selection Notes

Select this component when true dual-port functionality is required for concurrent processor access to shared memory resources. The 25ns access speed suits moderate-to-high frequency asynchronous interfaces. Consider the 100-pin TQFP package constraints regarding board space and thermal dissipation. Evaluate if the 5V TTL-compatible logic levels match the target system voltage requirements.
