70261S25PFI8

Memory IC Overview

The Renesas 70261S25PFI8 is a high-speed asynchronous dual-port static random-access memory (SRAM) with a density of 256 Kbit, organized as 16K words by 16 bits. It operates on a single 5V power supply and features a 25 ns access time. The device is housed in a 100-pin Thin Quad Flat Package (TQFP).

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from both ports.
• Includes on-chip hardware for semaphore signaling and port arbitration logic.
• Features automatic low-power standby mode controlled by chip enable signals.

Memory IC Applications

• Stand-alone dual-port RAM systems
• Master/Slave configurations for 32-bit or wider data bus architectures

Memory IC Procurement Notes

Verify RoHS compliance status and moisture sensitivity level before procurement. Confirm package dimensions and lead count match design requirements. Check current availability as this component may be subject to discontinuation or limited stock constraints.

Memory IC Selection Notes

Select this part for applications requiring true dual-port capability with hardware-based synchronization. Ensure the system voltage aligns with the 5V specification. Consider the 100-pin TQFP footprint for PCB layout compatibility.

Memory IC Part Context

This component belongs to the 70261 series of dual-port SRAMs. It shares architectural similarities with variants like the 70261L20PFI8 but differs in speed grade and specific suffix designations. It serves as a core memory element for high-throughput data buffering.

Memory IC Replacement Considerations

Consider the 70261L20PFGI8 as a potential upgrade path if faster access times are required. Verify pinout compatibility and electrical specifications before substitution.
