71V3556S100PFGI8

Overview

The IDT71V3556S100PFGI8 is a synchronous single data rate zero bus turnaround static random access memory integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 4.5 megabits, organized as 128 kilowords by 18 bits or 64 kilowords by 36 bits. The device operates with a maximum clock frequency of 100 MHz and features a typical access time of 5 nanoseconds. It utilizes a parallel interface and requires a supply voltage ranging from 3.135 volts to 3.465 volts. The component is housed in a 100-pin thin quad flat package measuring 14 by 14 millimeters.

Feature Summary

• Supports synchronous single data rate operation with zero bus turnaround capability for efficient bidirectional data transfer.
• Features a high-speed parallel interface optimized for system-level performance at 100 MHz clock frequencies.
• Designed for surface-mount installation within industrial temperature operating ranges.

Applications

• High-performance embedded systems requiring fast local memory buffering
• Network infrastructure equipment utilizing parallel SRAM interfaces

Procurement Notes

Verify the specific suffix PFGI8 against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as records indicate variations across production dates. Check current lifecycle status as the component may be subject to end-of-life notices. Ensure design-in approval accounts for moisture sensitivity level requirements during assembly processing.

Selection Notes

Select this component when a 4.5Mb synchronous SRAM with a 100-TQFP footprint is required. Compare access times and power consumption against alternative devices in the 71V3556 family. Verify that the 3.3V I/O levels match the target system logic standards. Consider the 100 MHz maximum clock speed relative to system bus requirements.

Part Context

This part belongs to the IDT 71V3556 series of synchronous zero bus turnaround SRAMs. The series offers various speed grades and package options including BGA and TQFP configurations.
