70261S25PFI

Memory IC Overview

The Renesas Electronics Corporation 70261S25PFI is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 256 Kbit organized as 16K words by 16 bits. The component supports a maximum access time of 25 nanoseconds and operates on a single 5V power supply with a voltage range of 4.5V to 5.5V. It is housed in a 100-pin Thin Quad Flat Package (TQFP) designed for surface-mount technology.

Memory IC Feature Summary

True dual-ported memory architecture enabling simultaneous independent access to the same memory location from both ports.
Integrated hardware support for semaphore signaling and port arbitration logic to manage bus conflicts.
Separate upper-byte and lower-byte control lines to facilitate multiplexed bus compatibility.
Automatic low-power standby mode controlled by chip enable inputs.

Memory IC Applications

Stand-alone dual-port RAM systems
Master/Slave dual-port configurations for 32-bit or wider word systems
High-speed data buffering applications

Memory IC Procurement Notes

Verify the specific suffix 'I' against official documentation to confirm industrial temperature grade specifications. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure pinout compatibility with existing PCB layouts when replacing legacy components.

Memory IC Selection Notes

Select this component for designs requiring concurrent read/write operations without external arbitration overhead. Consider the 100-pin TQFP package constraints for board space. Evaluate power consumption requirements against the automatic standby feature capabilities.

Memory IC Part Context

This part belongs to the 70261 series of dual-port SRAMs manufactured by Renesas Electronics. The series provides various speed grades and packaging options to accommodate different system timing and physical layout requirements.
