71V35761SA166BQI

Overview

The IDT71V35761SA166BQI is a 4.5 Mbit synchronous static random-access memory (SRAM) organized as 128K words by 36 bits. It operates at a maximum clock frequency of 166 MHz with a typical access time of 3.5 ns. The device utilizes a parallel interface and requires a supply voltage range of 3.135 V to 3.465 V. It is housed in a 165-CABGA package measuring 13x15 mm and supports an operating temperature range of 0°C to 70°C.

Feature Summary

• Synchronous Single Data Rate (SDR) architecture for high-speed data transfer
• Integrated burst counter for sequential address generation
• Pipelined output structure to maximize throughput
• Single-cycle deselect capability for flexible bus control

Applications

• High-performance cache memory systems
• Network routing equipment buffers
• Telecommunications signal processing units
• Industrial automation control modules

Procurement Notes

Verify the specific suffix 'BQI' against official Renesas or IDT documentation, as the provided source material primarily lists 'BQ' and 'BGGI' variants. Confirm current availability status, as related devices in this series have been marked as obsolete or end-of-life. Ensure RoHS compliance requirements are met, noting that some listed variants in the database show conflicting regulatory statuses.

Selection Notes

Select this component when a 36-bit wide data path is required for system integration. The synchronous interface simplifies timing design compared to asynchronous alternatives. Consider the 166 MHz speed grade if system latency constraints demand sub-4 ns access times. Evaluate the 165-ball BGA footprint for PCB layout compatibility and thermal management requirements.

Part Context

This part belongs to the IDT 71V35761 family of high-speed synchronous SRAMs. These devices are designed for applications requiring large block memory with fast access speeds. The family typically includes variations in speed grades, package types, and temperature ranges, all sharing the same core 128K x 36 organization and synchronous protocol.

Replacement Considerations

Publicly confirmed substitute part numbers for IDT71V35761SA166BQI were not found in the provided source material. Related variants such as IDT71V35761SA166BQ and IDT71V35761SA166BGGI share similar electrical characteristics but differ in package type and operating temperature range.
