71V3577S80BG

Overview

The Renesas Electronics Corporation 71V3577S80BG is a synchronous static random-access memory (SRAM) device organized as 128K x 36, providing a total storage capacity of 4.5 Mbit. It operates with an access time of 8 ns and supports a maximum clock frequency of 100 MHz. The component utilizes a parallel interface and functions within a supply voltage range of 3.135 V to 3.465 V. It is housed in a 119-pin PBGA package measuring 14x22 mm. The device is designed for surface mount installation and typically operates within a temperature range of 0°C to 70°C.

Feature Summary

• Supports synchronous single data rate (SDR) operation for high-speed data transfer
• Features flow-through architecture for continuous data output without wait states
• Includes self-timed write cycles controlled by global write and byte write enable signals

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control systems needing reliable volatile memory storage

Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be discontinued or subject to end-of-life notices. Confirm that the 119-PBGA package dimensions and pinout match your PCB design requirements. Ensure compatibility with 3.3V logic levels and check for any RoHS compliance restrictions if required by your manufacturing standards. Consult official distributor channels for availability updates.

Selection Notes

Select this component when a 128K x 36 organization is required for wide-data applications. The 8 ns access time suits systems operating at clock frequencies up to 100 MHz. Consider the 119-pin BGA package constraints for board space and thermal management. Verify that the synchronous interface aligns with your system controller's memory bus capabilities.

Part Context

This device belongs to the 71V3577 family of 3.3V synchronous SRAMs. It shares architectural similarities with other members like the 71V3577S80BGI, differing primarily in packaging or suffix variations. The family is characterized by its flow-through mode and support for interleaved or linear burst modes, targeting performance-critical embedded applications.
