7133SA90J8

Overview

The Renesas Electronics Corporation 7133SA90J8 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 utilizes an asynchronous parallel interface with a maximum access time of 90 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts 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 distinct processors or systems.

Applications

• High-speed data buffering in telecommunications equipment.

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 datasheet revisions against current design requirements before procurement.

Selection Notes

Evaluate system timing constraints against the 90 ns access specification. Ensure power supply stability within the 4.5V to 5.5V operating range. Consider thermal management requirements for the PLCC package in enclosed environments. Verify that the 2Kx16 organization matches the target application's data width needs.

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 for embedded memory applications. The 7133SA90J8 specifically denotes the 90 nanosecond speed variant in the standard PLCC form factor.

Replacement Considerations

The 7133LA25JGI is listed as an upgrade substitute. Verify functional equivalence and pinout compatibility before implementation.
