70261L15PFG8

Memory IC Overview

The Renesas Electronics Corporation 70261L15PFG8 is a high-speed 16K x 16 Dual-Port Static RAM designed for standalone or master/slave configurations in 32-bit systems. 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 single 5V power supply and includes automatic power-down features controlled by chip enable signals.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations
• Integrated hardware support for semaphore signaling and port arbitration between two ports
• Separate byte control mechanisms facilitating compatibility with multiplexed data buses
• Automatic low standby power mode activation via chip enable signal management

Memory IC Applications

• Standalone dual-port memory applications requiring concurrent read/write operations
• Master/slave dual-port RAM configurations for expanded 32-bit or wider word systems
• Systems requiring hardware-based synchronization through on-chip semaphore signaling

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm moisture sensitivity level handling requirements during storage and assembly. Check current RoHS compliance status against specific project regulations. Validate package marking accuracy to distinguish from similar suffix variants within the 70261 series family.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration circuitry. Consider the 100-pin TQFP package constraints for PCB layout density. Evaluate power consumption profiles against system thermal limits given the asynchronous operation characteristics. Ensure voltage supply stability within specified tolerances for reliable semaphore function execution.

Memory IC Part Context

This device belongs to the 70261 series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options including industrial temperature range variants. The L15 designation indicates a 15 nanosecond access time specification within this product line.

Memory IC Replacement Considerations

Officially documented substitute part numbers include 70261L15PFG (tray version) and 70261L20PFI8 (different speed grade). Verify pinout compatibility and electrical specifications before substitution.
