7133SA17PFI8

Overview

The Renesas Electronics Corporation 7133SA17PFI8 is a 32Kbit (2K x 16) dual-port asynchronous SRAM memory IC. It features a parallel interface with an access time of 17 ns and operates within a supply voltage range of 4.5V to 5.5V. The component is housed in a 100-TQFP package measuring 14x14 mm, designed for surface-mount installation.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous operation supporting flexible system timing integration
• CMOS technology ensuring low power consumption during standby and active states

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processing units
• Real-time data storage in industrial control applications

Procurement Notes

Verify the specific suffix PFI8 to confirm the 100-TQFP package and lead-free status. Confirm RoHS compliance requirements against current manufacturing standards. Check for end-of-life notices or obsolescence warnings from Renesas before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. Ensure the 17 ns speed meets system latency requirements. Verify that the 100-pin TQFP footprint fits the PCB layout constraints compared to other pin counts in the series.

Part Context

This part belongs to the 7133SA family of dual-port SRAMs. Variants differ primarily in access speed and package type. The SA designation indicates standard commercial temperature ranges, while LA variants support extended industrial temperatures. This specific model offers a balance of speed and pin count for dense board layouts.

Replacement Considerations

Direct substitutes include other 7133SA series parts with compatible pinouts. Verify electrical parameters such as access time and voltage levels match system requirements. Consider package compatibility if replacing with higher or lower speed variants.
