7133LA90JI8

Overview

The Renesas Electronics Corporation 7133LA90JI8 is a high-speed, 32K-bit (2K x 16) Dual-Port Static Random Access Memory (SRAM). It features parallel asynchronous interface with a maximum access time of 90 ns. The device operates on a single 5V power supply within the 4.5V to 5.5V range. It is housed in a 68-pin PLCC package measuring 24.21x24.21 mm and supports industrial temperature ranges.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations from two separate ports
• Asynchronous parallel interface for flexible system integration without clock synchronization requirements
• High-speed data handling capabilities optimized for demanding processing applications

Applications

• Stand-alone 16-bit dual-port RAM systems
• Master dual-port RAM configurations in complex memory hierarchies
• High-speed data buffering and protocol conversion tasks

Procurement Notes

Verify component authenticity through authorized distributors due to potential legacy status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Check for specific suffix variations that may indicate different packaging or temperature grades. Ensure supply chain stability as older generation components may face discontinuation risks.

Selection Notes

Select this component when independent concurrent access to 16-bit data words is required. The 90 ns speed suits moderate-to-high frequency applications. Consider the 68-PLCC package constraints for PCB layout. Evaluate thermal dissipation needs given the CMOS technology characteristics under standard operating conditions.

Part Context

Part of the 7133LA series of high-speed dual-port SRAMs designed by Renesas. This series provides versatile memory solutions for embedded systems requiring fast data exchange between processors or peripherals without bus contention issues typical in single-port memories.

Replacement Considerations

Direct substitutes include other 7133LA series variants with compatible pinouts and electrical specifications. Verify access time compatibility and package dimensions before substitution.
