71V3577S85BGI

Overview

The 71V3577S85BGI is a synchronous single data rate static random access memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5 Mbit organized as 128K x 36 bits. The device operates with a maximum clock frequency of 87 MHz and an access time of 8.5 ns. It utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a 119-pin PBGA package measuring 14x22 mm and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Supports burst mode operations offering four cycles of data for a single address presentation to enhance system performance.
• Includes self-timed write cycles controlled by global write control, byte write enable, and individual byte writes.
• Features low power down modes managed by the ZZ input pin to reduce energy consumption during idle states.

Applications

• High-performance networking equipment requiring fast data buffering
• Telecommunications systems utilizing wide bus architectures
• Industrial control systems needing reliable volatile memory storage

Procurement Notes

Verify current availability status as this component may be subject to end-of-life notices or production changes. Confirm that the specific package variant matches the required PCB footprint. Ensure compliance with environmental regulations relevant to the deployment region, noting RoHS status variations across manufacturing batches.

Selection Notes

Select this model when a 36-bit wide data path is required for synchronous memory applications. Compare against other variants in the 71V3577 series based on specific speed grades and package types such as TQFP or fpBGA if different form factors are needed. Ensure the design accommodates the 3.3V core and I/O voltage requirements.

Part Context

This part belongs to the 71V3577 family of 3.3V CMOS SRAMs designed for high-speed parallel data processing. The family offers various access times and package options to suit different system constraints. The S85 suffix indicates the specific 8.5 ns speed grade within this product line.

Replacement Considerations

Check for direct substitutes within the 71V3577 series with different speed grades or packages. Verify compatibility with alternative suppliers who may have produced identical components under previous corporate structures before the Renesas merger.
