7025L25PFI

Memory IC Overview

The Renesas Electronics Corporation 7025L25PFI 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 has a maximum access time of 25 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power current of 320 mA. It is housed in a TQFP-100 surface-mount package and functions within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes from two separate ports for high-throughput data handling
• Includes on-chip hardware semaphore signaling and port arbitration logic for efficient multi-processor coordination
• Features automatic power-down mode controlled by chip enable signals to minimize standby power consumption

Memory IC Applications

• Master/Slave dual-port RAM configurations in 32-bit or wider systems
• High-speed buffer memory in telecommunications equipment
• Data logging applications requiring non-volatile-like retention during battery backup

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Check for moisture sensitivity levels prior to soldering to prevent package damage during reflow processes.

Memory IC Selection Notes

Select this component when true dual-port functionality with hardware arbitration is required for complex system architectures. Ensure the 25 ns access time meets the timing constraints of the target application. Verify that the TQFP-100 package fits the available PCB footprint and thermal management strategy.
