71V3558S133PFG8

Memory IC Overview

The Renesas 71V3558S133PFG8 is a 4.5 Mbit synchronous single data rate (SDR) static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface with a storage organization of 256K x 18 bits. The device supports clock frequencies up to 133 MHz and offers an access time of 4.2 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and is designed for surface-mount installation in a 100-TQFP package measuring 14x14 mm. The component is classified as volatile memory and is available in tape-and-reel packaging.

Memory IC Feature Summary

• Supports high-speed synchronous operations with pipelined burst counter functionality
• Features 3.3 V I/O compatibility for system integration
• Utilizes a compact 100-pin thin quad flatpack no-lead package

Memory IC Applications

• High-performance computing systems requiring fast data buffering
• Industrial equipment control logic
• Network infrastructure signal processing

Memory IC Procurement Notes

Verify the specific suffix PFG8 to confirm the tape-and-reel packaging configuration, as other suffixes may indicate tray packaging. Confirm the operating temperature grade matches application requirements, noting that this specific part number typically corresponds to commercial temperature ranges. Check current lifecycle status, as synchronous SRAM products frequently undergo obsolescence notices or end-of-life declarations. Ensure RoHS3 compliance documentation is available if required by target market regulations.

Memory IC Selection Notes

Select this component when a 4.5 Mbit capacity with a 18-bit word width is required for synchronous parallel interfaces. Compare against the 71V3558S166PFG8 variant if higher clock speeds are necessary, while acknowledging potential pinout or timing differences. Consider the 71V3558S133PFG alternative if tray packaging is preferred over tape-and-reel. Evaluate power consumption specifications relative to system thermal constraints during continuous burst operations.

Memory IC Part Context

This device belongs to the IDT 71V3556/58 family of 3.3 V Synchronous ZBT SRAMs. The family includes variants with different densities and bus widths, such as the 128K x 36 configuration found in the 71V2556 series. These components are designed for applications demanding low latency and high throughput in embedded systems. The product line has transitioned from Integrated Device Technology to Renesas Electronics following corporate acquisitions.

Memory IC Replacement Considerations

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