71V3558S100PFGI8

Overview

The 71V3558S100PFGI8 is a synchronous single data rate (SDR) static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a total storage capacity of 4.5 Mbit, organized as 256K words by 18 bits. The device supports a maximum clock frequency of 100 MHz with an access time of 5 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and features a parallel interface. The component is housed in a 100-TQFP surface-mount package measuring 14x14 mm.

Feature Summary

• Supports high-speed synchronous data transfer at up to 100 MHz with 5 ns access latency.
• Utilizes Zero Bus Turnaround (ZBT) technology for efficient bus utilization.
• Features a flow-through architecture for predictable timing performance.
• Operates on a standard 3.3 V power supply with defined voltage tolerances.

Applications

• High-performance embedded systems requiring fast memory access
• Network infrastructure equipment
• Industrial automation controllers
• Telecommunications base stations

Procurement Notes

Verify current availability status as the component may be subject to end-of-life notices or production changes. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing PCB footprints and soldering profiles for the 100-TQFP package. Check for any recent product change notifications regarding pinout or electrical characteristics updates from the manufacturer.

Selection Notes

Select this part when a synchronous SRAM with 18-bit word width and 100 MHz operation is required. Compare against asynchronous alternatives if lower speed suffices. Consider the 100-TQFP package constraints for board space. Verify that the 3.3 V I/O levels match the system logic requirements. Evaluate thermal dissipation needs for the TQFP-100 form factor in enclosed environments.

Part Context

This component belongs to the 71V3558 series of synchronous SRAMs. It shares architectural similarities with other devices in the family, such as the 71V3558S100PF, differing primarily in packaging and environmental specifications. The series is designed for applications demanding high bandwidth and low latency memory solutions in industrial and commercial sectors.

Replacement Considerations

The IDT71V3558S100PFGI8 is listed as an alias for this part number. Verify pin-to-pin compatibility before substitution. Ensure the replacement matches the specific temperature grade and RoHS compliance status required for the application.
