71T75602S100PFG

Overview

The IDT71T75602S100PFG is a synchronous Single Data Rate Zero Bus Turnaround (ZBT) Static Random-Access Memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features an 18Mb storage capacity organized as 512K words by 36 bits. The device operates with a maximum clock frequency of 100 MHz and provides a typical access time of 5 ns. It utilizes a parallel interface and requires a supply voltage range of 2.375V to 2.625V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm, designed for surface-mount installation.

Feature Summary

• Supports high-performance system speeds through synchronous ZBT technology that eliminates dead cycles between write and read operations.
• Features internally synchronized output buffer enable to remove the need for external Output Enable (OE) control.
• Includes positive clock-edge triggered address, data, and control signal registers for fully pipelined applications.
• Provides individual byte write control capabilities via dedicated BW pins.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Frame buffering in video processing systems
• FIFO buffers in digital signal processing architectures

Procurement Notes

Verify the specific suffix 'PFG' against official Renesas documentation to confirm package type and temperature range, as distributor listings may vary. Confirm RoHS compliance status, as some variants are marked non-compliant. Check current lifecycle status, as this part number may be discontinued or subject to last-time buy restrictions. Ensure the source document explicitly identifies the manufacturer as Renesas Electronics Corporation for the IDT brand lineage.

Selection Notes

Select this component when a 36-bit wide data path is required for high-throughput applications. The 100 MHz speed grade suits systems needing moderate latency without the complexity of dual-port architectures. Consider the 100-TQFP package if board space allows for leaded packages, noting potential RoHS constraints. Evaluate power consumption requirements against the 2.5V core voltage specifications provided in the datasheet.

Part Context

This device belongs to the IDT71T75602/802 family of synchronous ZBT SRAMs. The family includes variants with different access times and clock frequencies, such as the 133 MHz version. The product line was originally developed by Integrated Device Technology before being acquired by Renesas Electronics. These components are designed to replace asynchronous SRAMs in high-speed designs while maintaining pin compatibility with standard SRAM interfaces.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify cross-references with other 18Mb 36-bit ZBT SRAMs from Renesas or other manufacturers only if official substitution lists are consulted.
