70261S15PFG8

Memory IC Overview

The Renesas Electronics Corporation 70261S15PFG8 is a high-speed 256Kbit (16K x 16) dual-port static random-access memory. It features asynchronous parallel interface with 15 ns access time and operates on a single 4.5V to 5.5V supply. The component utilizes a 100-pin TQFP surface-mount package and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

True dual-ported memory architecture enabling simultaneous independent access to the same memory location by two separate ports.
Integrated hardware support for semaphore signaling and port arbitration logic to manage data conflicts between ports.
Separate upper-byte and lower-byte control lines designed for compatibility with multiplexed bus systems.

Memory IC Applications

Stand-alone dual-port RAM configurations in embedded systems.
Master/Slave dual-port RAM combinations for 32-bit or wider word data processing architectures.
High-speed data buffering applications requiring concurrent read/write operations.

Memory IC Procurement Notes

Verify RoHS compliance status as historical records indicate non-compliance for this specific suffix variant. Confirm current lifecycle status, as documentation references discontinuation notices for the broader 70261 series. Ensure availability of compatible replacement components if sourcing new production units is restricted due to end-of-life conditions.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required without external arbitration circuitry. The 100-pin TQFP package suits space-constrained printed circuit board layouts. Verify that the system power supply strictly adheres to the 4.5V to 5.5V range to ensure reliable operation within the specified industrial temperature limits.

Memory IC Part Context

This device belongs to the 70261 family of high-speed dual-port SRAMs manufactured by Renesas Electronics. The family provides flexible memory solutions for complex digital signal processing and communication systems. Variations in the family differ primarily by access speed, package type, and operating temperature grade.
