7133SA70JI8

Overview

The Renesas Electronics Corporation 7133SA70JI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features asynchronous parallel interface operation with a maximum access time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

Dual-port architecture enabling independent simultaneous access from two separate processors or systems
Asynchronous parallel interface for straightforward integration into standard digital logic designs
CMOS technology construction ensuring low power consumption relative to older bipolar alternatives

Applications

High-speed data buffering between disparate processing units
FIFO queue implementation in communication protocols
Cache memory subsystems in embedded control architectures

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin compatibility during replacement planning. Check for RoHS compliance variations across manufacturing lots. Validate electrical specifications against original design requirements before final integration.

Selection Notes

Evaluate the 70ns access speed against system timing constraints. Ensure the 68-PLCC footprint matches existing PCB layout. Consider thermal management requirements within the specified operating temperature range. Assess availability of compatible socketing solutions for prototyping and maintenance phases.

Part Context

This component belongs to the 7133SA series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options to suit different performance and form-factor requirements in industrial and commercial electronic applications.
