7134SA25J8

Overview

The Renesas Electronics Corporation 7134SA25J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 4K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 25 nanoseconds and a write cycle time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-lead PLCC package.

Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations on separate ports
Asynchronous parallel interface for straightforward system integration
High-speed data access capabilities suitable for performance-critical applications

Applications

Data buffering in high-speed communication systems
Cache memory implementation in embedded processing units
Temporary storage in industrial control equipment

Procurement Notes

This component has been officially discontinued and is no longer in active production. Verify end-of-life status through official manufacturer channels before design finalization. Sourcing is restricted to existing stock or secondary markets. Ensure compliance with RoHS non-compliance declarations and check for valid replacement alternatives from the same product family.

Selection Notes

Select this part only if legacy compatibility with 32Kb dual-port SRAM specifications is required. Confirm that the 52-PLCC package footprint matches the target PCB layout. Evaluate whether modern single-port or higher-density alternatives meet system requirements, considering the discontinuation status and potential supply chain constraints for obsolete components.

Part Context

The 7134SA series belongs to Renesas' portfolio of high-performance dual-port SRAMs. These devices are designed for applications requiring concurrent access from two different masters. The SA suffix typically denotes specific speed grades and packaging options within the broader 7134 family, which includes variants with different access times and pin configurations.
