7025L20PF

Memory IC Overview

The Renesas Electronics Corporation 7025L20PFI is an asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 128 kbit, organized as 8K x 16. It features a parallel interface and a maximum access time of 20 ns. The device operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V, with a maximum power current of 320 mA. It supports surface-mount installation in a TQFP-100 package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory cells enabling simultaneous independent reads from the same memory location by both ports.
• Integrated hardware support for semaphore signaling and port arbitration logic to manage concurrent access conflicts.
• Separate upper-byte and lower-byte control lines designed for compatibility with multiplexed bus architectures.

Memory IC Applications

• Stand-alone high-speed dual-port RAM systems
• Master/Slave dual-port configurations for 32-bit or wider word data systems
• Industrial embedded applications requiring extended temperature operation

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the standard version may not meet current environmental directives. Validate pinout compatibility with existing PCB layouts before procurement. Check for moisture sensitivity level handling requirements during assembly.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required without external arbitration logic. Ensure the design accommodates the 100-pin TQFP footprint and 5V logic levels. Consider the 20 ns access speed relative to system clock requirements. Verify that the industrial temperature range meets the operational environment specifications.

Memory IC Part Context

The 7025 series represents a family of high-speed asynchronous dual-port SRAMs manufactured by Renesas Electronics. These devices are engineered for applications demanding high bandwidth and low latency between two independent processors or controllers sharing a common memory space.

Memory IC Replacement Considerations

The 7025L20PFGI is documented as a direct replacement or upgrade option for the 7025L20PFI variant.
