7025L20PFG

Memory IC Overview

The Renesas Electronics Corporation 7025L20PFG is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 128 kilobits, organized as 8K words by 16 bits per word. The component features a parallel interface with a maximum access time of 20 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) with dimensions of 14x14 mm. It supports industrial temperature ranges 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 support for semaphore signaling, allowing efficient synchronization between the two ports.
• Automatic power-down functionality controlled by Chip Enable signals to minimize standby power consumption.
• Separate upper-byte and lower-byte control lines to facilitate multiplexed bus compatibility.

Memory IC Applications

• Stand-alone 128K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 32-bit or wider data bus expansion
• High-speed data buffering in telecommunications equipment
• Network switch and router packet processing buffers

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as specific suffixes may indicate non-compliant variants. Confirm package type accuracy, as similar part numbers exist with different pin counts or lead forms. Check for active Product Change Notices regarding labeling or assembly site changes. Ensure the supplier provides original manufacturer documentation to verify authenticity and traceability.

Memory IC Selection Notes

Select this component when true simultaneous access to shared memory locations is required. Choose based on the 20ns access speed requirement and 100-pin TQFP footprint constraints. Consider the 5V logic level compatibility with existing system buses. Evaluate the need for hardware semaphore support versus software-based locking mechanisms.

Memory IC Part Context

This part belongs to the Renesas 7025 series of high-speed dual-port SRAMs. The series offers various access speeds and package options to suit different performance and form-factor requirements. It is designed for applications requiring high bandwidth and low latency data sharing between two processors or controllers.

Memory IC Replacement Considerations

Check for direct replacements such as the 7025L20PFGI8 variant, which shares the same electrical specifications but differs in packaging format. Verify pinout compatibility before substitution to ensure proper board integration.
