71V3577S75BQG

Overview

The 71V3577S75BQG is a synchronous static random-access memory integrated circuit manufactured by Renesas Electronics. It features a storage organization of 128K x 36 bits, providing a total capacity of 4.5 Mbit. The device supports a maximum clock frequency of 117 MHz with an access time of 7.5 ns. It operates on a 3.3V core supply and utilizes 3.3V I/O levels. The component is housed in a 165-pin CABGA package.

Feature Summary

• Supports high-speed synchronous burst operations with selectable interleaved or linear modes
• Includes self-timed write cycles controlled by global write control and byte write enables
• Features power-down functionality managed via the ZZ input pin

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control applications needing reliable volatile memory storage

Procurement Notes

Verify the specific suffix BQG to confirm the 165-pin CABGA package configuration. Ensure compatibility with 3.3V logic levels for both core and I/O domains. Check for RoHS compliance status as manufacturing updates may affect environmental certifications. Confirm availability through authorized distributors due to potential lifecycle changes.

Selection Notes

Select this component when a 128K x 36 organization is required for wide data bus applications. The 7.5 ns access time suits designs demanding high throughput. Consider the 165-pin CABGA package for surface-mount assembly constraints. Verify that the system design can accommodate the synchronous interface timing requirements.

Part Context

This part belongs to the 71V3577 family of 3.3V CMOS SRAMs. The family offers various package options including TQFP, PBGA, and CABGA. The S75 suffix typically denotes the 7.5 ns speed grade within the series. These devices are designed for applications requiring flowthrough output and boundary scan capabilities.

Replacement Considerations

Check for direct substitutes within the 71V3577 family with different package codes. Verify equivalent speed grades from other manufacturers if pin-compatible alternatives are needed. Ensure replacement parts maintain the same 128K x 36 organization and 3.3V operating voltage.
