71V3556SA133BGG

Overview

The IDT71V3556SA133BGG is a 4.5 Mbit synchronous ZBT SRAM with a 128K x 36 organization, housed in a 119-pin PBGA package (14x22 mm). It operates at a maximum clock frequency of 133 MHz with a 4.2 ns access time. The device features 3.3V I/O and supports pipelined burst operations.

Feature Summary

• Synchronous Zero Bus Turnaround (ZBT) technology eliminates dead cycles between read and write operations.
• Pipelined architecture with internal output buffer enable for high-speed system performance.
• Supports 4-word burst capabilities in interleaved or linear modes.

Applications

• High-performance networking equipment
• Telecommunications systems
• Industrial control applications

Procurement Notes

Verify the RoHS compliance status carefully, as official documentation indicates this specific part number may be non-compliant compared to other variants in the series. Confirm current availability as the product line has been subject to discontinuation notices by the manufacturer.

Selection Notes

Select this component when a 128K x 36 memory configuration is required with 133 MHz synchronous operation. Ensure the design accommodates the 119-pin BGA footprint and 3.3V logic levels. Consider alternative speeds if higher frequencies are needed.

Part Context

This part belongs to the IDT71V3556/58 family of 3.3V Synchronous ZBT SRAMs. The 'SA' suffix typically denotes a specific speed grade within the 133 MHz range, while 'BGG' identifies the plastic BGA package variant.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs before considering any cross-reference alternatives.
