71V35761S166PFG8

Overview

The IDT71V35761S166PFG8 is a synchronous single data rate (SDR) static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. 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 and is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Supports pipelined burst operations with a dedicated burst counter for sequential data transfers.
• Features single-cycle deselect capability to terminate burst cycles immediately without waiting for completion.
• Designed with pipelined outputs to eliminate dead bus cycles during read-to-write or write-to-read transitions.

Applications

• High-speed digital signal processing systems requiring low-latency memory access.
• Network infrastructure equipment utilizing parallel SRAM interfaces.
• Industrial control systems operating within the specified temperature range.

Procurement Notes

Verify the exact suffix PFG8 against official Renesas documentation, as distributors may list similar variants like PFGI8 which differ in lead finish or RoHS compliance. Confirm current availability status as this series has faced end-of-life notifications. Ensure the procurement channel provides valid traceability for the specific manufacturing lot and date code required for your application.

Selection Notes

Select this component when a 36-bit wide parallel interface is required for high-throughput applications. The 166 MHz speed grade offers a balance between performance and power consumption compared to faster variants. Verify that the system design accommodates the 100-pin TQFP footprint and that the 3.3V I/O levels match the host processor requirements.

Part Context

This part belongs to the IDT 71V35761 family of synchronous SRAMs. The 'S' designation typically indicates standard commercial or industrial temperature grades depending on the specific suffix, while '166' denotes the 166 MHz speed bin. The family is characterized by its ability to handle mixed read/write bursts efficiently in complex memory architectures.

Replacement Considerations

Check for the 71V35761SA166PFGI8 variant if RoHS compliance is mandatory, as the base model may not meet current environmental standards. Other speed grades such as 200 MHz variants exist but require verification of timing compatibility.
