71T75802S100PFG

Overview

The IDT71T75802S100PFG is a Synchronous Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) manufactured by Integrated Device Technology. It features a memory organization of 1M x 18 bits, providing a total capacity of 18 Megabits. The device operates with a maximum clock frequency of 100 MHz and supports an access time of 5 nanoseconds. It utilizes a 2.5V core voltage supply and includes 2.5V I/O buffers for interface compatibility. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14mm x 20mm.

Feature Summary

• Supports high-performance system speeds through synchronous ZBT architecture that eliminates dead cycles between write and read operations.
• Features internally synchronized output buffer enable to simplify control logic by removing the need for external Output Enable management.
• Includes positive clock-edge triggered registers for address, data, and control signals to support fully pipelined applications.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Data storage in industrial automation control systems

Procurement Notes

Verify the specific suffix 'PFG' against official Renesas or IDT documentation to confirm package type and lead-free status. Ensure the operating temperature range matches the application requirements. Confirm current availability as this component may be subject to lifecycle changes or obsolescence notices from the manufacturer.

Selection Notes

Select this component when a 18Mb synchronous SRAM with 5ns access time is required. It is suitable for designs needing ZBT technology to maximize bus throughput without turnaround latency. Consider the 100-pin TQFP package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the IDT 71T75802 family of Synchronous ZBT SRAMs. These devices are designed to offer high-density memory solutions with fast access times. The family typically includes various speed grades and package options to accommodate different system performance needs and form factor requirements.

Replacement Considerations

Check for direct substitutes within the 71T75802 series with different speed grades or packages. Verify pinout compatibility before replacing with other vendors' synchronous ZBT SRAMs.
