7009L15PFG8

Memory IC Overview

The 7009L15PFG8 is a high-speed 128K x 8 Dual-Port Static RAM designed for standalone or master/slave configurations. It features true dual-ported memory cells allowing simultaneous reads of the same location, on-chip port arbitration logic, and hardware semaphore signaling. The device operates asynchronously from either port with TTL-compatible single 5V power supply (4.5V to 5.5V). It includes an automatic power-down feature controlled by CE for low standby power and supports battery backup operation with 2V data retention. The component is housed in a 100-pin TQFP package.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations
• Integrated on-chip port arbitration logic and full hardware support for semaphore signaling between ports
• Automatic power-down mode controlled by chip enable to minimize standby power consumption
• Battery backup capability ensuring data retention at voltages as low as 2V

Memory IC Applications

• Stand-alone 1M-bit dual-port memory systems
• Master/slave dual-port RAM combinations for 16-bit or wider word systems
• High-speed asynchronous data buffering applications

Memory IC Procurement Notes

Verify component status carefully as this part number may be obsolete. Confirm availability through authorized distributors only. Check for lead-free compliance markings such as Pb-Free Terminals on packaging labels. Ensure proper handling for moisture sensitivity level 3 components. Validate that the specific suffix matches required temperature grades and packaging types.

Memory IC Selection Notes

Select this component when simultaneous read access to identical memory addresses is required without external arbitration. Suitable for systems needing hardware-based semaphore signaling for port control. Consider the 100-pin TQFP package constraints and 5V logic compatibility. Evaluate power-down requirements against the automatic standby mode capabilities.

Memory IC Part Context

This device belongs to the Renesas 7009 series of dual-port SRAMs. It provides high-speed asynchronous operation with integrated control logic. The series supports expansion to wider data buses through master/slave configurations. It is designed for industrial applications requiring reliable concurrent access and low power states.

Memory IC Replacement Considerations

Check official manufacturer documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical specifications before substitution. Ensure replacement parts meet the same temperature range and package requirements.
