71V25761S166PFGI8

Overview

The 71V25761S166PFGI8 is a synchronous Single Data Rate (SDR) Static Random Access Memory (SRAM) 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 166 MHz with an access time of 3.5 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and has a maximum power current of 330 mA. The component is housed in a TQFP-100 package and is designed for surface mount installation.

Feature Summary

• Supports high-speed parallel data transfer via synchronous interface architecture
• Provides wide 36-bit data bus width for efficient memory bandwidth utilization
• Operates on a single 3.3V core voltage supply for simplified power design

Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications infrastructure systems utilizing pipeline SRAM
• Industrial control systems needing reliable volatile data storage

Procurement Notes

Verify the specific suffix PFGI8 against official Renesas documentation to confirm pinout compatibility and moisture sensitivity level before integration. Confirm RoHS compliance status and lead-free specifications directly from the manufacturer datasheet, as these attributes are critical for regulatory adherence and assembly processes.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required for system architectures demanding low latency and high throughput. Ensure the host system supports the 3.3V logic levels and that the TQFP-100 footprint aligns with the printed circuit board layout constraints and thermal management requirements.

Part Context

This part belongs to the 71V25761S family of synchronous pipelined SRAMs. These devices are engineered to eliminate dead bus cycles during read-to-write or write-to-read transitions, thereby maximizing data throughput efficiency in complex digital signal processing and communication applications.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic cross-references may not match the specific 36-bit organization or synchronous timing characteristics required for direct pin-to-pin replacement.
