70261S15PFG

Memory IC Overview

The 70261S15PFG 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, with separate upper-byte and lower-byte control for multiplexed bus compatibility. The device includes on-chip port arbitration logic, semaphore signaling support, and automatic power-down modes controlled by chip enable inputs.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access from both ports
• On-chip hardware support for semaphore signaling and port arbitration between masters and slaves
• Separate byte control lines facilitating multiplexed bus compatibility and data width expansion
• Automatic low standby power mode activated via chip enable control

Memory IC Applications

• Standalone dual-port memory modules
• Master/slave dual-port RAM combinations for 32-bit or wider systems
• High-speed data buffering in parallel interface applications

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Ensure supply chain documentation matches the specific suffix requirements for temperature grade and packaging type.

Memory IC Selection Notes

Select this part for applications requiring simultaneous read/write access from two independent processors. Verify voltage compatibility with the single 5V supply requirement. Consider the 100-pin TQFP package constraints for PCB layout and thermal management in dense designs.
