71V35761SA166BQG

Overview

The IDT71V35761SA166BQG is a synchronous single data rate static random access memory integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 4.5 megabits, organized as 128 kilowords by 36 bits. The device supports a maximum clock frequency of 166 MHz with an access time of 3.5 nanoseconds. It operates within a supply voltage range of 3.135 volts to 3.465 volts and utilizes a parallel interface. The component is housed in a 165-contact CABGA package measuring 13 by 15 millimeters.

Feature Summary

• Supports synchronous single data rate operation for high-speed data transfer
• Features pipelined burst architecture for efficient sequential access
• Includes parity bit generation and checking for data integrity verification

Applications

• High-performance networking equipment requiring fast buffer memory
• Telecommunications systems utilizing pipeline burst SRAM

Procurement Notes

Verify the specific suffix designation carefully, as variations such as BQG and BQGI may indicate differences in packaging or compliance status. Confirm current manufacturing status, as this part number has been subject to end-of-life notifications. Ensure compatibility with existing board layouts regarding the 165-CABGA footprint and thermal requirements before procurement.

Selection Notes

Select this component when a 36-bit wide data path is required for system bus alignment. The 166 MHz speed grade suits applications demanding low latency without the complexity of double data rate interfaces. Consider the operating temperature range and power consumption limits relative to the target enclosure design and cooling capabilities.
