7034L15PF

Memory IC Overview

The Renesas Electronics Corporation 7034L15PF is a static random access memory component with a storage capacity of 72 kbit. It features an organization of 4 k x 18 and utilizes a parallel interface type. The device has an access time of 15 ns and operates within a power supply voltage range of 4.5 V to 5.5 V. It supports surface mount installation in a TQFP-100 package. The operational temperature range spans from 0 C to + 70 C, and it employs SDR storage type technology.

Memory IC Feature Summary

• Supports simultaneous independent read operations at both ports for true dual-port functionality
• Includes on-chip hardware support for semaphore signaling between ports
• Features automatic power down mode controlled by Chip Enable signals

Memory IC Applications

• Stand-alone high-speed dual-port RAM systems
• Master/Slave dual-port RAM configurations for wider word systems
• Battery backup operation requiring data retention

Memory IC Procurement Notes

Verify the obsolete status and end-of-life notice before procurement planning. Confirm RoHS compliance requirements as the component may not meet current environmental standards. Check moisture sensitivity levels for proper handling during assembly. Ensure replacement strategies are in place due to discontinuation. Validate pin compatibility if substituting with newer variants.

Memory IC Selection Notes

Select this component for applications requiring asynchronous dual-port SRAM with 15 ns access speed. Consider the 4 k x 18 organization for specific data width needs. Verify that the 5V supply voltage aligns with system design constraints. Ensure the TQFP-100 package fits the PCB layout requirements. Account for the industrial temperature range limitations in harsh environments.

Memory IC Part Context

This part belongs to the 7034L15 series of dual-port RAM devices manufactured by Renesas Electronics. It is designed for high-speed data buffering and sharing between two independent processors or systems. The series emphasizes full on-chip arbitration and interrupt flag capabilities to manage concurrent access efficiently without external logic.

Memory IC Replacement Considerations

Check for direct upgrades such as the 7035L15PFG which offers similar dual-port functionality. Verify package compatibility and electrical specifications when considering substitutes. Review manufacturer notices for recommended obsolescence management strategies.
