71V3577S75BG8

Overview

The 71V3577S75BG8 is a 4.5 Mbit synchronous static random-access memory (SRAM) organized as 128K x 36 bits, manufactured by Renesas Electronics Corporation. It operates with a 3.3V core supply and supports a maximum clock frequency of 117 MHz with a 7.5 ns access time. The device utilizes a parallel interface and is housed in a 119-pin PBGA package measuring 14x22 mm. It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed synchronous operation with flow-through output architecture for minimal latency.
• Features self-timed write cycles controlled by global write control and byte write enable signals.
• Includes LBO input to select between interleaved or linear burst modes for optimized data transfer.

Applications

• High-performance networking equipment requiring fast data buffering
• Industrial automation systems needing reliable volatile memory storage
• Telecommunications infrastructure utilizing synchronous bus interfaces

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as older batches may not meet current environmental standards. Check for moisture sensitivity level requirements during handling and storage to prevent package damage. Ensure the specific suffix matches the required package type and temperature grade for your design.

Selection Notes

Select this component when a 36-bit wide data path is required for system integration. Consider the 119-pin BGA footprint for PCB layout constraints. Evaluate thermal management needs given the power consumption characteristics at 117 MHz. Compare against ZBT alternatives if zero bus turnaround performance is critical for the application.
