71V3558S166PFG

Memory IC Overview

The IDT71V3558S166PFG is a synchronous ZBT SRAM with a 4.5Mb capacity organized as 256K x 18 bits. It operates at a maximum clock frequency of 166 MHz with a 3.0 ns access time. The device uses a 100-pin TQFP package and supports 3.3V I/O levels within a 3.135V to 3.465V supply range. It features pipelined outputs, a burst counter, and single-cycle deselect capabilities for efficient data handling.

Memory IC Feature Summary

• Supports high-speed synchronous operation with pipelined output architecture
• Includes integrated burst counter and single-cycle deselect functionality
• Utilizes Zero Bus Turnaround (ZBT) technology for improved throughput

Memory IC Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment such as routers and switches
• Industrial control systems demanding reliable data storage
• Telecommunications base stations and signal processing units

Memory IC Procurement Notes

Verify the specific suffix PFG to confirm the 100-TQFP package type and lead-free status. Ensure compatibility with 3.3V logic levels in the target design. Check for RoHS compliance documentation if required by regional regulations. Confirm availability through authorized Renesas or IDT distributors as this component may be subject to lifecycle changes.

Memory IC Selection Notes

Select this part when a 256K x 18 organization is required with synchronous interface capabilities. The 166 MHz speed grade offers a balance between performance and power consumption. Consider the TQFP package for surface-mount applications where pin count and thermal properties are critical. Compare against other speed grades like 133 MHz or 200 MHz based on system timing requirements.
