7133SA25JI

Overview

The Renesas Electronics Corporation 7133SA25JI is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 2K words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 68-pin PLCC package. The component is designed for commercial temperature applications ranging from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• CMOS technology providing high-speed asynchronous operation
• Single 5V power supply compatibility

Applications

• High-performance embedded systems requiring concurrent data access
• Industrial control units needing fast local data buffering
• Communication equipment utilizing parallel data interfaces

Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited production runs. Confirm RoHS compliance requirements against specific project standards, as older variants often lack lead-free certification. Ensure proper handling procedures are established due to moisture sensitivity classification. Validate that the 68-PLCC package dimensions match the target PCB footprint constraints before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for a 32K x 16 configuration. Compare against the 7133LA series if extended industrial temperature ranges are necessary. Consider the 7133SA55 variant if slower speeds suffice but different packaging is preferred. Verify that the 25 ns access time meets the system timing requirements for the intended application speed.

Part Context

This part belongs to the Renesas 7133SA family of CMOS dual-port SRAMs. These devices are engineered for applications demanding high throughput and independent port access. The family typically includes variations in speed grades and package types, such as PGA and PLCC options, catering to diverse board layout and performance needs across commercial electronics sectors.

Replacement Considerations

Check for direct substitutes like the IDT7133SA25J, which shares identical electrical specifications and pinout compatibility. Evaluate the 7133SA25J8 variant if tape-and-reel packaging is preferred over tubes. Ensure any replacement maintains the 68-pin PLCC form factor and 25 ns access speed.
