71V3577YS75PFG

Overview

The IDT71V3577YS75PFG is a high-speed synchronous SRAM organized as 128K x 36. It features a 4.2 ns clock access time and operates at a maximum frequency of 133 MHz. The device utilizes a 3.3V core power supply with 3.3V I/O levels. It is housed in a 100-pin plastic thin quad flatpack (TQFP) package, specifically the 100-TQFP (14x14) configuration.

Feature Summary

• Supports burst mode operations with an internal burst address counter for sequential data access.
• Features a flow-through architecture with no registers in the data output path.
• Includes self-timed write cycle generation controlled by global write control signals.

Applications

• High-performance cache memory systems
• Network infrastructure equipment
• Telecommunications hardware

Procurement Notes

Verify the specific suffix 'S75' against official Renesas or IDT documentation to confirm the exact speed grade and pinout compatibility. Ensure the TQFP-100 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 128K x 36 organization is required with synchronous interface capabilities. The 133 MHz operating speed makes it suitable for applications demanding low latency and high throughput without the complexity of pipelined architectures.

Part Context

This part belongs to the IDT 71V3577/79 family of 3.3V Synchronous SRAMs. These devices are designed for high-speed data buffering and caching applications, offering a balance between performance and system integration simplicity through their flow-through output design.

Replacement Considerations

Cross-reference with IDT71V3577SA or IDT71V3577S variants for potential pin-compatible alternatives. Verify electrical specifications and package dimensions carefully when considering substitutes from other manufacturers.
