71V3577S85BGI8

Overview

The 71V3577S85BGI8 is a synchronous single data rate static random access memory manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5 Mbit organized as 128K x 36. The device operates with an access time of 8.5 ns and supports a maximum clock frequency of 87 MHz. It utilizes a parallel interface and functions within a supply voltage range of 3.135 V to 3.465 V. The component is housed in a 119-pin PBGA package measuring 14x22 mm and is designed for surface mount installation.

Feature Summary

Supports synchronous SDR burst mode operations for high-performance data transfer
Includes self-timed write cycles with global write control capabilities
Features power-down functionality controlled by the ZZ input pin

Applications

High-speed digital signal processing systems
Network infrastructure equipment requiring fast buffer memory
Industrial automation controllers needing rapid data access

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity level handling procedures during storage and assembly. Ensure replacement strategies are in place given the discontinuation notice from the manufacturer.

Selection Notes

Select this component when specific 128K x 36 organization and 8.5 ns access times are required. Consider the 119-pin BGA package constraints for PCB layout design. Evaluate thermal performance within the specified operating temperature range. Assess system compatibility with 3.3V I/O levels and synchronous clocking requirements.

Part Context

This part belongs to the 71V3577 family of synchronous SRAMs. It shares architectural similarities with other variants in the series but differs in speed grade and packaging. The device represents a legacy solution for applications previously relying on fast parallel memory interfaces before widespread adoption of newer memory technologies.
