71V25761S200PFG

Memory IC Overview

The IDT71V25761S200PFG is a 4.5 Mbit synchronous static random-access memory (SRAM) integrated circuit manufactured by Integrated Device Technology, Inc. It features a memory organization of 128K words by 36 bits and operates at a clock frequency of 200 MHz with a typical access time of 3.1 ns. The device utilizes a 100-pin Thin Quad Flat Package (TQFP) or LQFP surface-mount housing. It functions on a 3.3 V supply voltage with 2.5 V I/O levels and supports single-cycle deselect operations.

Memory IC Feature Summary

• Supports pipelined output architecture for high-speed data transfer
• Integrates an internal burst counter for sequential access efficiency
• Enables single-cycle deselect to reduce power consumption during idle states

Memory IC Applications

• High-performance networking equipment requiring low-latency buffering
• Telecommunications systems utilizing parallel interface protocols
• Industrial control systems demanding reliable volatile memory storage

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas or IDT distributors due to discontinuation status. Confirm RoHS compliance requirements as original manufacturing may differ from current standards. Validate package integrity upon receipt to ensure pin alignment matches the 100-pin TQFP specification before integration into printed circuit boards.

Memory IC Selection Notes

Select this component when a 36-bit wide parallel interface is required for system compatibility. Ensure the design accommodates the specific 3.3 V core voltage and 2.5 V I/O logic levels. Consider the 100-pin footprint constraints during PCB layout planning to maintain signal integrity at 200 MHz operation speeds.

Memory IC Part Context

This part belongs to the IDT 71V25761S family of synchronous SRAMs. It shares architectural similarities with variants like the SA200BG8 but differs in package type and pin count. The series is characterized by its pipeline depth and burst capability, designed for applications needing fast random access within a fixed memory density constraint.

Memory IC Replacement Considerations

Consult official Product Discontinuance Notices for confirmed substitute part numbers. Verify that any replacement maintains the 128K x 36 bit organization and compatible 100-pin TQFP/LQFP footprint to ensure mechanical and electrical interchangeability without redesigning the host board.
