71V3577S85BGG

Overview

The 71V3577S85BGG is a 4.5 Mbit synchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a parallel interface and is organized as 128K x 36 bits. The device supports an access time of 8.5 ns with a maximum clock frequency of 87 MHz. It operates on a 3.3V core supply voltage within a range of 3.135V to 3.465V. The component is housed in a 165-pin CABGA package and 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-performance embedded systems requiring fast data access
• Network infrastructure equipment
• Industrial automation controllers

Procurement Notes

Verify the specific suffix BQG against official Renesas documentation to confirm the 165-pin CABGA package configuration. Confirm that the 8.5 ns speed grade matches system timing requirements. Check current availability status as this component may be subject to discontinuation notices. Ensure compatibility with 3.3V I/O levels in the target design.

Selection Notes

Select this part when a 36-bit wide synchronous SRAM interface is required. The 8.5 ns access time suits applications needing moderate-speed burst data retrieval. Consider the 165-pin CABGA package constraints for PCB layout. Verify that the operating temperature range meets environmental specifications.

Part Context

This component belongs to the 71V3577 family of 3.3V CMOS SRAMs. It shares architectural similarities with other devices in the series but differs in package type and speed grade. The family typically offers flow-through output options and boundary scan capabilities.

Replacement Considerations

Consult official Renesas substitution guides for equivalent parts. Verify pinout compatibility and electrical characteristics before replacing.
