71V3556S100PFG8

Overview

The 71V3556S100PFG8 is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 4.5 Mbit, organized as 128K x 36 bits. The device supports a maximum clock frequency of 100 MHz with a typical access time of 5 ns. It operates on a single 3.3V power supply within a range of 3.135V to 3.465V. The component utilizes a parallel interface and is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x20 mm. It is designed for surface mount installation.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead bus cycles during read-to-write or write-to-read transitions.
• Synchronous Single Data Rate (SDR) operation allows data transfer aligned with the system clock.
• Integrated address and control signal registers facilitate pipelined data access.

Applications

• High-speed digital signal processing systems
• Network infrastructure equipment requiring low-latency buffering
• Industrial automation controllers

Procurement Notes

Verify current availability status as this component may be subject to end-of-life notices. Confirm package variant compatibility, as suffixes indicate specific pin configurations. Check for moisture sensitivity level requirements prior to soldering. Ensure voltage levels match system specifications. Consult official distributors for obsolete part alternatives if necessary.

Selection Notes

Select this component when a 128K x 36 organization is required for synchronous memory applications. The ZBT technology is suitable for designs needing efficient bus turnaround without pipeline stalls. Consider the 100-TQFP package for standard surface-mount assembly processes. Verify thermal performance within the specified operating temperature range.

Part Context

This SRAM belongs to the 71V3556 series, which includes various speed grades and package options. The 'S' designation typically indicates standard commercial or industrial temperature ranges depending on the specific suffix. The '100' denotes the 100 MHz clock capability. This series is part of Renesas's broader portfolio of high-performance memory solutions.

Replacement Considerations

The 71V547S100PFGI8 is listed as a similar replacement option. Verify electrical parameters and pinout compatibility before substitution. Other family members like the 71V3556SA100BQI offer different package types such as BGA.
