71V3577YS85PFG

Overview

The Renesas Electronics 71V3577YS85PFG is a high-speed synchronous static random access memory organized as 128K x 36. It features a flow-through architecture with 3.3V I/O and operates on a 3.3V core supply. The device supports an 8.5ns access time, corresponding to a maximum clock frequency of 87MHz. It utilizes a parallel interface and is housed in a 100-pin thin quad flatpack package.

Feature Summary

• Supports fast access times up to 8.5ns for high-performance data throughput
• Features a self-timed write cycle with global write control and byte-level granularity
• Includes an LBO input to select between interleaved or linear burst modes
• Provides power-down capabilities controlled by the ZZ input pin

Applications

• High-speed cache memory systems
• Network routing equipment buffers
• Industrial control system data storage

Procurement Notes

Verify the specific suffix PFG against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Ensure the ordering code matches the required industrial temperature range specifications. Confirm RoHS compliance status prior to procurement as manufacturing processes may evolve.

Selection Notes

Select this component when a 36-bit data width is required for synchronous applications. The flow-through output architecture minimizes latency compared to registered outputs. Verify that the system voltage aligns with the 3.3V core and I/O requirements for proper operation.

Part Context

This part belongs to the IDT 71V3577 series of synchronous SRAMs. The series includes variants with different access speeds and memory organizations, such as the 256K x 18 configuration found in the 71V3579 model. The 'S' designation typically indicates commercial and industrial temperature ranges.
