7133LA55J8

Overview

The Renesas Electronics Corporation 7133LA55J8 is a 32Kbit (2K x 16) CMOS dual-port static random-access memory (SRAM). It features asynchronous parallel interface operation with a maximum access time of 55 ns. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-PLCC package measuring 24.21x24.21 mm. It is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface supporting standard bus protocols
• CMOS technology ensuring low power consumption relative to performance

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring wide temperature tolerance

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm package integrity upon receipt, as moisture sensitivity level 3 requires proper handling. Cross-reference datasheet revisions to ensure compatibility with existing system designs before procurement.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. Ensure the design accommodates the 68-PLCC footprint and thermal requirements for the specified industrial temperature range. Validate that the 55 ns access time meets the system timing constraints.

Part Context

This part belongs to the Renesas 7133SA/LA series of high-speed dual-port SRAMs. It shares architectural similarities with other variants in the family but differs in speed grade and packaging. The 'LA' suffix typically denotes specific commercial/industrial temperature ranges and package types compared to other series members.

Replacement Considerations

IDT7133SA55JI8 is a documented equivalent part number from the same manufacturer lineage. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
