7133SA55PF

Overview

The Renesas Electronics Corporation 7133SA55PF is a 32Kb (2K x 16) asynchronous dual-port static random-access memory (SRAM). It features a parallel interface with a maximum access time of 55 ns and operates within a supply voltage range of 4.5V to 5.5V. The device is housed in a 100-TQFP surface-mount package with dimensions of 14x14 mm. It supports an industrial operating temperature range from 0°C to 70°C.

Feature Summary

• Provides independent read/write ports for simultaneous data access by two masters
• Supports asynchronous operation with fast 55 ns access times
• Utilizes CMOS technology for low power consumption

Applications

• High-speed data buffering in communication systems
• Cache memory in embedded processing applications
• Data storage in industrial control equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as this specific variant may not meet current environmental regulations. Validate package integrity and pin alignment against the 100-TQFP specification before integration into production assemblies.

Selection Notes

Select this component when dual-port functionality is required for concurrent master access. Ensure system voltage aligns with the 4.5V to 5.5V operational range. Consider the 100-TQFP footprint constraints during PCB layout design. Verify thermal requirements against the 0°C to 70°C industrial temperature rating.

Part Context

This part belongs to the 7133SA series of asynchronous dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family but differs in speed grade and packaging. The 7133SA series is designed for applications requiring high-bandwidth, independent port access without complex arbitration logic.

Replacement Considerations

The 7133LA20PFG is listed as an upgrade alternative.
