71V35761S166PFG

Overview

The Renesas Electronics Corporation 71V35761S166PFG is a synchronous single data rate static random-access memory integrated circuit. It features a storage capacity of 4.5 Mbit organized as 128K words by 36 bits. The device supports a maximum clock frequency of 166 MHz with an access time of 3.5 ns. It operates on a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a surface-mount TQFP-100 package.

Feature Summary

• Supports pipelined burst operations to eliminate dead bus cycles during read/write transitions
• Features 3.3V I/O levels for system compatibility
• Includes a single cycle deselect capability for flexible control

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring fast access times

Procurement Notes

Verify the exact suffix designation, as the provided model lacks the final character typically indicating RoHS compliance or tape-and-reel packaging. Confirm current manufacturing status, as many variants in this series are discontinued. Ensure the selected replacement matches the specific pinout and electrical characteristics required for the target design.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM is required for high-throughput applications. The 166 MHz speed class suits designs needing low latency. Consider the TQFP-100 package constraints for PCB layout. Evaluate alternative packages like BGA if higher density or different thermal performance is needed for the specific enclosure.

Part Context

This part belongs to the IDT 71V35761 family of synchronous SRAMs. These devices are designed for high-performance computing and networking. The family offers various speed grades and package options to accommodate different system requirements while maintaining consistent core functionality and interface protocols.

Replacement Considerations

Publicly confirmed substitute part numbers include 71V35761SA166BQGI and 71V3577S75BQG from Renesas Electronics Corporation.
