71T75802S100PFGI

Overview

The IDT 71T75802S100PFGI is a synchronous Zero Bus Turnaround (ZBT) static random-access memory integrated circuit. It features an 18 Mbit storage capacity organized as 1 Megabit by 18 bits. The device supports a maximum clock frequency of 100 MHz with a typical access time of 5 nanoseconds. It operates on a 2.5V core supply voltage and utilizes a 100-pin Thin Quad Flat Package (TQFP) housing.

Feature Summary

• Supports high-performance system speeds through Zero Bus Turnaround technology, eliminating dead cycles between write and read operations.
• Features internally synchronized output buffers that remove the requirement for external Output Enable control signals.
• Includes positive clock-edge triggered registers for address, data, and control signals to enable fully pipelined applications.

Applications

• High-speed digital signal processing systems
• Network infrastructure equipment requiring low-latency buffering
• Embedded systems utilizing synchronous burst memory architectures

Procurement Notes

Verify the specific suffix PFGI against official Renesas or IDT documentation to confirm package type and moisture sensitivity level. Ensure compatibility with existing board layouts regarding the 100-pin TQFP footprint and pin assignments before procurement.

Selection Notes

Select this component when a 1M x 18 organization is required with synchronous interface capabilities. The 100 MHz speed grade suits designs needing moderate latency without the complexity of asynchronous timing. Confirm power supply requirements align with the specified 2.5V core voltage range.

Part Context

This part belongs to the IDT 71T75802 series of synchronous ZBT SRAMs. The family includes variants with different speed grades and packaging options, such as BGA configurations. The 71T75802 designation specifically denotes the 1M x 18 bit density within this product line.

Replacement Considerations

Check for direct cross-references from Renesas Electronics, which acquired IDT's memory business. Verify if alternative speed grades like the S133 variant are electrically compatible with the current design constraints.
