7025L45PFI

Memory IC Overview

The Renesas Electronics Corporation 7025L45PFI is a dual-port static random-access memory integrated circuit with a storage capacity of 128 kbit, organized as 8K x 16. It features an asynchronous parallel interface and a maximum access time of 45 ns. The device operates on a single 5V power supply ranging from 4.5 V to 5.5 V. It is housed in a 100-pin Thin Quad Flatpack (TQFP) package designed for surface mount installation. The component supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from two separate ports without conflict.
• Integrated hardware semaphore signaling logic that facilitates port arbitration and data synchronization between the two ports.
• Supports cascading multiple devices to expand data bus width beyond 16 bits using Master/Slave select configurations.

Memory IC Applications

• High-speed digital signal processing systems requiring concurrent data access
• Telecommunications equipment utilizing multiplexed bus architectures
• Industrial control networks needing reliable dual-port memory coordination

Memory IC Procurement Notes

Verify current manufacturing status before procurement as lead finishes may be discontinued. Confirm RoHS compliance requirements against specific project standards. Ensure the 100-TQFP footprint matches the target PCB layout. Validate voltage levels and temperature ratings for the intended operational environment.

Memory IC Selection Notes

Select this component when true dual-port functionality is required for complex data sharing between processors. Consider the 45 ns access speed relative to system clock requirements. Evaluate the 100-pin TQFP package constraints against available board space. Compare power consumption characteristics against other asynchronous SRAM options.
