71V3577S80BQ8

Overview

The Renesas Electronics Corporation 71V3577S80BQ8 is a 4.5 Mbit synchronous single data rate static random access memory integrated circuit. It features a parallel interface and is organized as 128K x 36 bits. The device supports a maximum clock frequency of 100 MHz with an access time of 8 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and is housed in a 165-pin CABGA package measuring 13x15 mm. The component is designed for surface mount installation.

Feature Summary

• Supports synchronous burst mode operations with selectable interleaved or linear modes via the LBO input
• Features self-timed write cycles controlled by global write control, byte write enable, and individual byte writes
• Includes power-down functionality managed by the ZZ input pin

Applications

• High-speed digital signal processing systems
• Network infrastructure equipment requiring fast data buffering
• Industrial automation controllers
• Telecommunications base station modules

Procurement Notes

Verify current availability status as this component has been marked as obsolete by the manufacturer. Confirm that the 165-pin CABGA package dimensions match your PCB footprint requirements. Ensure compliance with RoHS non-compliance declarations if environmental regulations apply to your specific deployment environment. Check for any relevant product change notices regarding substrate or labeling updates.

Selection Notes

Select this component when a 36-bit wide data path is required for high-throughput applications. The 100 MHz operating speed suits designs needing moderate latency without the complexity of double data rate interfaces. Consider the 165-pin package size constraints during layout planning. Verify that the system power supply can maintain the specified voltage range under all load conditions.

Part Context

This part belongs to the 71V3577 family of synchronous SRAMs from Renesas. It shares architectural similarities with other members like the 71V3577S80BG but differs in packaging and moisture sensitivity classification. The family is characterized by its flowthrough output architecture and 3.3V I/O compatibility.

Replacement Considerations
