71V3558S133PFGI

Memory IC Overview

The IDT71V3558S133PFGI is a synchronous single data rate zero bus turnaround SRAM manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5 Mbit organized as 256K x 18 bits. The device operates with a maximum clock frequency of 133 MHz and offers an access time of 4.2 ns. It utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a 100-TQFP (14x14) surface-mount package and supports an operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports synchronous single data rate operation with zero bus turnaround capability for efficient data transfer.
• Features pipelined outputs and a burst counter for high-speed memory access.
• Designed for 3.3V I/O compatibility within standard SRAM architectures.

Memory IC Applications

• High-performance computing systems requiring fast cache memory
• Network infrastructure equipment needing low-latency data buffering
• Industrial control systems utilizing real-time processing

Memory IC Procurement Notes

Verify the specific suffix 'GI' against official Renesas documentation, as it may indicate lead-free or RoHS compliance status distinct from non-GI variants. Confirm current lifecycle status, as this part number is associated with discontinuation notices. Ensure the required package type matches the design footprint before procurement.

Memory IC Selection Notes

Select this component when a 256K x 18 organization is required for synchronous applications. Compare against the IDT71V3558XS133PF if alternative packaging or compliance standards are needed. Evaluate thermal performance within the specified commercial temperature range during system integration.

Memory IC Part Context

This part belongs to the IDT71V3558 family of synchronous ZBT SRAMs. It shares architectural similarities with other members like the IDT71V3556 and IDT71V3558SA series, differing primarily in speed grades, package types, and organizational configurations such as 36-bit widths.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers include 71V3558S166PFG and 71V3558S166PFGI. Verify pinout and electrical specifications before substitution.
