7133SA70JI

Overview

The Renesas Electronics Corporation 7133SA70JI is a 32Kb (2K x 16) dual-port asynchronous static random-access memory (SRAM). It features parallel interface access with a 70 ns write cycle time and voltage supply range of 4.5V to 5.5V. The component utilizes a 68-PLCC surface-mount package and operates within an industrial temperature range of -40°C to 85°C.

Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations on two ports
Asynchronous parallel interface for flexible system integration
Industrial-grade operational temperature capability

Applications

High-speed data buffering in telecommunications equipment
Cache memory implementation in embedded processing systems
Data storage in industrial control applications

Procurement Notes

This component has been officially discontinued by the manufacturer and is no longer in production. Verification of availability should focus exclusively on authorized distributors offering remaining stock or approved upgrade alternatives. Confirm RoHS compliance status, as this specific part does not meet current environmental standards. Validate that any substitute components maintain identical pinout and electrical specifications to ensure seamless replacement.

Selection Notes

Select this component only when legacy design compatibility with the 68-PLCC package and 70 ns timing is strictly required. Verify that the operating environment remains within the specified -40°C to 85°C range. Ensure power supply constraints align with the 4.5V to 5.5V requirement. Consider that discontinuation necessitates long-term supply chain risk assessment before finalizing the design.

Part Context

The 7133SA series represents a family of high-performance dual-port SRAMs designed for demanding applications requiring concurrent port access. This specific model belongs to the 70 ns speed grade variant, balancing performance with standard CMOS technology. It serves as a critical memory solution for systems needing reliable, fast data handling capabilities across diverse industrial and commercial sectors.
