71V35761S166PF

Overview

The IDT71V35761S166PF is a 4.5 Mbit synchronous static random-access memory (SRAM) IC manufactured by Integrated Device Technology Inc. It features a parallel interface with a memory organization of 128K x 36 bits. The device operates at a clock frequency of 166 MHz and provides an access time of 3.5 ns. It utilizes a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. The component supports 3.3V I/O levels and includes internal synchronization for address, data, and control signals.

Feature Summary

• Supports high-performance system speeds through fully pipelined output buffers and positive clock-edge triggered registers.

Applications

• High-speed data buffering in network infrastructure equipment
• Cache memory implementation in telecommunications systems
• Data storage in industrial automation controllers

Procurement Notes

Verify the specific suffix 'PF' to confirm the 100-TQFP package configuration. Confirm RoHS compliance status as legacy documentation may vary. Check for active manufacturing status or obsolescence notices from Renesas Electronics, the current successor manufacturer. Ensure voltage supply requirements match the target system design before procurement.

Selection Notes

Select this component when a 128K x 36 bit capacity is required with 166 MHz synchronous operation. The 3.5 ns access time suits applications needing low-latency parallel data access. The 100-TQFP package is suitable for standard surface-mount assembly processes. Consider pin compatibility if replacing older asynchronous SRAM designs.

Part Context

This part belongs to the IDT 71V35761 family of 3.3V Synchronous SRAMs. These devices are designed for burst counter operations and single-cycle deselect functionality. The family typically offers various package options including BGA and TQFP configurations to accommodate different board space constraints.

Replacement Considerations

Consult official datasheets for cross-reference equivalents. Verify that substitute parts maintain the 128K x 36 organization and 166 MHz speed grade. Ensure pinout compatibility with the existing 100-TQFP footprint.
