70261L35PF

Memory IC Overview

The Renesas Electronics Corporation 70261L35PF 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 with TTL-compatible single 5V power supply (4.5V to 5.5V). It includes automatic power-down features controlled by CE for low standby power modes.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations
• On-chip hardware support for semaphore signaling and port arbitration between ports
• Separate byte control lines facilitating multiplexed bus compatibility and data width expansion

Memory IC Applications

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

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Check for specific RoHS compliance status as older variants may differ. Ensure pinout compatibility with target PCB design before finalizing procurement orders.

Memory IC Selection Notes

Select this component when simultaneous bidirectional access to shared memory is required without external arbitration circuitry. Suitable for systems needing fast asynchronous operation with standard 5V logic levels. Consider thermal management requirements for surface mount installations in enclosed environments.

Memory IC Part Context

Part of the 70261 series of high-speed dual-port SRAMs designed for demanding real-time processing applications. Manufactured using advanced CMOS technology to ensure reliability and performance consistency across industrial temperature ranges.

Memory IC Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-reference electrical specifications and pinouts carefully when evaluating alternatives.
