71V3557S75PFGI

Overview

The Renesas 71V3557S75PFGI is a static random-access memory (SRAM) integrated circuit belonging to the ZBT family. It provides a storage capacity of 4.5 Mbit organized as 128K words by 36 bits. The device features a parallel interface with an access time of 7.5 ns and operates on a single 3.3V power supply within a voltage range of 3.135V to 3.465V. It is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm, designed for surface-mount installation.

Feature Summary

• Supports synchronous Single Data Rate (SDR) operation utilizing Zero Bus Turnaround (ZBT) technology for efficient data transfer.
• Features a wide 36-bit data bus architecture suitable for high-performance processing applications.
• Includes dedicated chip enable inputs to manage power consumption during inactive periods.

Applications

• High-speed digital signal processing systems
• Network communication equipment requiring fast buffer memory
• Industrial control systems with strict timing requirements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure proper handling procedures are followed to prevent electrostatic discharge damage during storage and installation processes.

Selection Notes

Select this component when a 36-bit data width is required for system compatibility. Consider the 7.5 ns access speed against system clock requirements. Evaluate the TQFP package constraints regarding board space and thermal dissipation capabilities compared to alternative BGA options.
