7133SA55PF8

Overview

The 7133SA55PF8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features asynchronous parallel interface operation with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 100-pin Thin Quad Flat Package (TQFP).

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on both ports.
• Asynchronous parallel interface for straightforward integration into standard digital systems.
• CMOS technology providing high-speed performance with low power consumption characteristics.

Applications

• High-performance embedded memory systems requiring concurrent data access.
• Industrial control applications utilizing parallel bus architectures.
• Telecommunications equipment needing reliable volatile data storage buffers.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific package markings against official datasheets before procurement. Check for obsolescence notices or lifecycle changes that may affect long-term supply stability.

Selection Notes

Select this component when dual-port functionality is required for 32Kb parallel memory applications. Ensure the design accommodates the 100-TQFP footprint and 4.5V-5.5V operating voltage range. Consider alternative speed grades if faster access times are needed, or verify compatibility with existing system timing requirements.

Part Context

This part belongs to the Renesas 7133SA series of dual-port SRAMs. It shares architectural similarities with other variants in the family but differs in speed grade and packaging options. The 'PF8' suffix typically denotes specific tape-and-reel packaging configurations for automated assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers were not identified in the provided source material. Verify cross-compatibility with similar 32Kb dual-port SRAMs from the same manufacturer family based on pinout and electrical specifications.
