7133SA90GM

Overview

The Renesas Electronics Corporation 7133SA90GM is a dual-port static random-access memory (SRAM) integrated circuit. It features 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 leaded chip carrier package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations from two separate ports.

Applications

• High-speed data buffering in telecommunications equipment.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential obsolescence risks. Confirm the specific suffix designation matches project requirements, as variations may indicate differences in packaging or environmental compliance status. Request official datasheets and product change notifications to ensure compatibility with existing design specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring independent concurrent access to shared memory resources without external arbitration logic. Ensure the system power supply remains stable within the specified voltage limits to maintain reliable operation. Verify that the PCB footprint accommodates the 68-PLCC package dimensions and thermal requirements for the intended operating environment.

Part Context

This part belongs to the 7133SA series of dual-port SRAMs manufactured by Renesas Electronics. The series provides non-volatile-like performance with volatile memory speed, serving as a bridge between fast processors and slower peripheral devices. The 7133SA90GM variant specifically denotes the 90-nanosecond access speed grade within this family.

Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Substitutions must match the 32Kb capacity, 2Kx16 organization, and 68-PLCC package form factor to ensure mechanical and electrical compatibility.
