71V3558XS133PFGI

Overview

The IDT71V3558XS133PFGI is a 4.5 Mbit synchronous ZBT SRAM with a 256K x 18 organization, operating at 133 MHz with 4.2 ns access time. It features 3.3V I/O and pipelined outputs in a 100-TQFP package.

Feature Summary

• Supports high-performance system speeds with zero wait states between read and write cycles
• Internally synchronized output buffer enable eliminates external OE control requirements
• Positive clock-edge triggered address and data registers for fully pipelined applications

Applications

• High-speed networking equipment
• Telecommunications systems
• Industrial automation controllers

Procurement Notes

Verify RoHS compliance status as the specific XS133PF variant may differ from standard lead-free versions. Confirm package dimensions against 100-TQFP specifications. Check end-of-life status and availability of tape-and-reel alternatives like IDT71V3558XS133PF8.

Selection Notes

Select this component for designs requiring low-latency memory with burst capabilities. Ensure voltage supply matches 3.135V to 3.465V range. Consider thermal performance within 0°C to 70°C operating temperature limits.

Part Context

Part of the IDT71V3556/58 family offering 128Kx36 and 256Kx18 configurations. Designed for 3.3V applications with ZBT technology to maximize throughput without dead cycles.

Replacement Considerations

IDT71V3558XS133PF8 offers identical electrical characteristics in tape-and-reel packaging.
