7134SA25L48M

Overview

The Renesas Electronics Corporation 7134SA25L48M is a high-speed 32Kbit (4K x 8) dual-port static random-access memory (SRAM). It features fully asynchronous operation with a maximum access time of 25 nanoseconds. The device utilizes a parallel interface and operates on a single 5V power supply, ranging from 4.5V to 5.5V. It is housed in a 48-lead LCC package designed for surface-mount installation. The component supports industrial temperature ranges and includes automatic power-down capabilities controlled by chip enable signals.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to the same memory location from both ports without hardware arbitration.
• Fully asynchronous operation allowing flexible timing control for systems requiring external arbitration or contention handling.
• Automatic power-down feature that reduces standby current consumption when chip enable inputs are deactivated.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers

Procurement Notes

Verify the specific suffix 'M' against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for active obsolescence notices or product discontinuance notifications prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring true dual-port functionality with asynchronous timing flexibility. Ensure the system can handle potential bus contention during simultaneous port accesses. Verify that the 48-lead LCC package fits the available PCB footprint and that the 5V logic levels match the host interface requirements.

Part Context

This part belongs to the IDT 7134 series of dual-port SRAMs, originally developed by Integrated Device Technology and now manufactured by Renesas Electronics. The series is widely recognized for its high-speed performance and reliability in applications demanding concurrent read/write operations from two distinct masters.

Replacement Considerations

Official upgrades include the 71342LA25PFGI8. Verify pin compatibility and electrical specifications before substitution.
