70261L12PF8

Memory IC Overview

The Renesas Electronics Corporation 70261L12PF8 is a high-speed 16K x 16 Dual-Port Static RAM. It features true dual-ported memory cells allowing simultaneous access to the same location, separate upper-byte and lower-byte control for multiplexed bus compatibility, and on-chip port arbitration logic with semaphore signaling support. The device operates asynchronously from either port using a TTL-compatible single 5V power supply and is available in a 100-pin TQFP package within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations by two distinct ports.
• Integrated hardware support for semaphore signaling and automatic power-down modes controlled by chip enable signals.

Memory IC Applications

• Stand-alone dual-port memory systems
• Master/Slave dual-port configurations for 32-bit or wider word systems

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm specific suffix designations against official datasheets to ensure correct package type and temperature grade alignment. Review moisture sensitivity levels and handling requirements prior to assembly to prevent damage during soldering processes.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration circuitry. Ensure system voltage matches the specified 5V tolerance and verify that the 100-pin TQFP footprint fits the target PCB layout constraints. Consider thermal management capabilities within the industrial operating range.

Memory IC Part Context

This part belongs to the 70261 series of dual-port SRAMs designed for high-performance data buffering and communication between processors. It serves as a critical interface element in complex embedded systems requiring fast, conflict-free memory sharing between multiple masters.

Memory IC Replacement Considerations

Consult official substitution lists for equivalent speed grades and pin-compatible alternatives such as the 70261L15PFGI if timing requirements allow for slower access speeds.
