71V3577S85PF

Overview

The IDT71V3577S85PF is a high-speed synchronous static random-access memory (SRAM) device manufactured by Integrated Device Technology, now part of Renesas Electronics. It features a storage capacity of 4.5 Mbit organized as 128K words by 36 bits. The component supports a maximum clock frequency of 87 MHz with an access time of 8.5 ns. It operates on a single 3.3V power supply within the range of 3.135V to 3.465V. The device utilizes a parallel interface and is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Feature Summary

• Supports synchronous operation with a flow-through architecture for direct data output without internal pipeline registers.
• Includes an internal burst address counter to handle sequential data accesses efficiently.
• Features self-timed write cycles that allow write termination decisions at the end of the cycle.

Applications

• High-performance cache memory systems
• Network routing equipment buffers
• Telecommunications signal processing

Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices from the manufacturer. Confirm package authenticity and check for moisture sensitivity level requirements during handling. Ensure compatibility with existing system voltage levels and interface protocols before integration into new designs.

Selection Notes

Select this component when a 36-bit wide data path is required for synchronous applications. Consider the 8.5 ns access speed and 87 MHz clock limit against system timing constraints. Evaluate the 100-TQFP package dimensions for PCB layout space. Compare against alternative densities if 4.5 Mbit exceeds specific design needs.

Part Context

This device belongs to the IDT 71V3577/79 series of synchronous SRAMs. These parts are designed for high-speed data buffering and caching applications requiring low latency. The series typically includes variants with different access times and organizational structures to suit various performance tiers in embedded systems.
