70261L20PFGI8

Memory IC Overview

The Renesas Electronics Corporation 70261L20PFGI8 is a high-speed, 256-kbit (16K x 16) dual-port static random-access memory (SRAM). It features asynchronous parallel interface operation with a maximum access time of 20 ns. The device operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. It is housed in a 100-pin TQFP surface-mount package and supports an industrial operating temperature range 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 bus conflicts between ports.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption.

Memory IC Applications

• Stand-alone dual-port RAM systems requiring concurrent data access.
• Master/Slave dual-port configurations for expanding data bus widths to 32 bits or more.
• Industrial control applications requiring reliable memory in extended temperature environments.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as specific suffixes may vary. Check current lifecycle status as this part number may be subject to discontinuation or obsolescence notices. Ensure proper ESD handling procedures are followed during storage and assembly.

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. Evaluate power requirements against the specified 5V supply tolerance. Compare access times if higher speed performance is needed for the target application frequency.

Memory IC Part Context

This component belongs to the Renesas 70261 series of dual-port SRAMs. It shares architectural similarities with other variants in the family, such as different access speeds or packaging options. The series is designed for applications needing high-reliability memory with hardware-managed port control.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades within the 70261 series. Verify that alternative dual-port SRAMs maintain compatible semaphore and interrupt flag functionality. Ensure replacement packages match the 100-pin TQFP footprint.
