71V25761S166PFGI

Overview

The Renesas 71V25761S166PFGI is a Synchronous Single Data Rate (SDR) Static Random Access Memory (SRAM) integrated circuit. It provides a total storage capacity of 4.5 Mbit, organized as 128K words by 36 bits. The device supports a maximum clock frequency of 166 MHz with a typical access time of 3.5 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and features a parallel interface. The component is housed in a 100-pin TQFP package suitable for surface mount technology.

Feature Summary

• Supports synchronous single data rate operations for high-speed data transfer
• Provides wide 36-bit data word width for efficient bus interfacing
• Features pipelined architecture to maintain throughput at high clock frequencies

Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications systems utilizing wide data buses
• Industrial control systems needing rapid random access memory

Procurement Notes

Verify the specific suffix PFGI to confirm the 100-pin TQFP package and lead-free status. Confirm RoHS compliance details directly from the manufacturer datasheet. Ensure the design accounts for the specified 3.3V power supply requirements and operating temperature range of -40°C to +85°C. Check for any recent product change notices regarding pinout or electrical characteristics.

Selection Notes

Select this component when a 36-bit data width is required for system bus compatibility. The 166 MHz speed rating suits applications demanding low latency and high bandwidth. Consider the TQFP-100 package constraints for PCB layout and thermal management. Compare against other members of the 71V25761S family if different speeds or packages are needed.

Part Context

This part belongs to the Renesas 71V25761S series of synchronous SRAMs. The series offers various speed grades and package options to accommodate different performance and form factor requirements. The 166 MHz variant balances speed and power consumption for mid-range synchronous memory applications.

Replacement Considerations

The IDT71V25761S166PFGI is an equivalent part number from the same product lineage. Verify pin compatibility and electrical specifications before substitution. Other speed grades in the series may require timing adjustments.
