7133SA45J8

Memory IC Overview

The Renesas Electronics Corporation 7133SA45J8 is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 2048 words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 45 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 package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations on separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing units
• Data storage in industrial control applications

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity and pin alignment against the 68-PLCC specification before integration into final assemblies.

Memory IC Selection Notes

Select this component for designs requiring independent port access without bus contention. Ensure the system power supply remains stable between 4.5V and 5.5V. Verify that the PCB layout accommodates the specific dimensions of the 68-PLCC package and meets thermal dissipation requirements for the operating temperature range.

Memory IC Part Context

This SRAM belongs to the 7133SA series, which features asynchronous dual-port technology. The 45ns speed grade indicates its suitability for moderate-to-high frequency applications compared to faster variants like the 35ns or 20ns models within the same family.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider verifying compatibility with other 7133SA series variants such as the 7133SA35J if timing specifications allow.
