71V3577S65PFG

Overview

The IDT71V3577S65PFG is a synchronous single data rate 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 117 MHz with an access time of 6.5 ns. It operates on a 3.3V power supply within a voltage range of 3.135V to 3.465V and is housed in a 100-pin TQFP package.

Feature Summary

• Supports high-speed parallel interface with burst mode capabilities for efficient data transfer
• Includes self-timed write cycles controlled by global write control and byte write enable signals
• Features low-power operation with power-down modes managed by the ZZ input pin

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment utilizing synchronous SRAM
• Industrial control applications needing reliable volatile memory storage

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence. Confirm RoHS compliance status as older batches may not meet current environmental standards. Check for moisture sensitivity level requirements during handling and storage to prevent damage. Ensure replacement parts match the specific suffix codes for package and temperature variations.

Selection Notes

Select this component for designs requiring 36-bit wide data paths and synchronous operation up to 117 MHz. Consider the 100-TQFP package for surface-mount assembly compatibility. Evaluate thermal performance within the specified operating temperature range. Compare against newer generations if lead-free compliance is mandatory for the target market.

Part Context

This part belongs to the 71V3577 family of synchronous SRAMs designed for high-speed data processing. It complements other variants like the 71V3579 which offers different organization or speed grades. The series is widely used in telecommunications and networking hardware where deterministic latency is critical for system stability.
