IDT71T75802S100PFGI

Memory IC Overview

The IDT71T75802S100PFGI is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a total storage capacity of 18 Mbit, organized as 1M x 18 bits. The device features a parallel interface and operates at a maximum clock frequency of 100 MHz with an access time of 5 ns. It functions within a supply voltage range of 2.375 V to 2.625 V. The component is housed in a 100-pin TQFP package measuring 14x14 mm.

Memory IC Feature Summary

• Supports synchronous single data rate (SDR) operation for high-speed data transfer
• Integrates zero bus turnaround (ZBT) technology to minimize latency during direction changes
• Utilizes a 1M x 18 bit organization architecture for wide data applications

Memory IC Applications

• High-performance embedded systems requiring fast local memory
• Industrial automation controllers needing rapid data buffering
• Telecommunications equipment utilizing synchronous processing

Memory IC Procurement Notes

Verify the specific suffix PFGI against the official datasheet to confirm the package type and temperature rating. Ensure compatibility with existing board layouts for the 100-TQFP form factor. Check for moisture sensitivity levels if reflow soldering is required. Confirm RoHS compliance status for current production batches. Validate that the 2.5V core voltage aligns with system power rails.

Memory IC Selection Notes

Select this component when a 100 MHz synchronous SRAM with 18-bit width is required. Compare access times against faster variants like the S133 or S200 series if higher speeds are needed. Consider the TQFP package constraints versus BGA options for thermal management. Evaluate power consumption specifications relative to system cooling capabilities. Ensure the 18-bit organization matches the data bus width of the host processor.

Memory IC Part Context

This part belongs to the IDT71T75802S family of synchronous ZBT SRAMs. The family offers various speed grades and packaging options to suit different performance requirements. Renesas acquired the IDT product line, maintaining these specifications under the Renesas brand. The 18 Mbit density is common in mid-range memory applications.

Memory IC Replacement Considerations

Direct substitutes include other speed grades within the same family such as IDT71T75802S133PFGI or IDT71T75802S200PFI, provided pin compatibility is verified. Cross-referencing with legacy IDT part numbers is necessary due to the acquisition history.
