71V3557S80PFI

Overview

The IDT71V3557S80PFI is a Synchronous ZBT SRAM with a capacity of 4.5Mb (128K x 36). It features an 8 ns access time and operates on a 3.3V supply voltage ranging from 3.135V to 3.465V. The device utilizes a parallel interface and is housed in a 100-TQFP package measuring 14x14 mm. It supports a commercial operating temperature range of 0°C to 70°C.

Feature Summary

• Supports synchronous burst counter and flow-through output modes for flexible data transfer.

Applications

• High-speed data buffering in telecommunications equipment.

Procurement Notes

Verify the component status as discontinued or obsolete through official Renesas channels. Confirm RoHS compliance history, as older batches may not meet current environmental standards. Ensure the 100-TQFP package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this part for applications requiring 36-bit wide synchronous memory interfaces. Compare against the IDT71V547S80PFI if a different organization is needed. Verify that the 3.3V I/O levels are compatible with the host system logic voltages.

Part Context

This component belongs to the IDT 71V3557 family of Synchronous ZBT SRAMs. It shares architectural similarities with other members like the IDT71V3557SA85BG but differs in package type and specific timing characteristics. The series is designed for high-performance embedded memory applications.
