71T75802S100BGGI

Overview

The IDT71T75802S100BGGI is a synchronous static random access memory integrated circuit manufactured by Renesas Electronics. It features an 18-megabit storage capacity organized as 1M x 18 bits. The device supports parallel interface operations with a maximum clock frequency of 100 MHz and a typical access time of 5 ns. It operates within a supply voltage range of 2.375V to 2.625V. The component is housed in a 119-pin PBGA package measuring 14x22 mm and is rated for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Zero bus turnaround architecture eliminates dead cycles between read and write operations
• Single read/write control pin simplifies system design by removing separate output enable requirements
• Internal synchronization of the output buffer enables fully pipelined application support

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial automation controllers needing reliable volatile memory
• Network equipment utilizing synchronous SRAM interfaces

Procurement Notes

Verify the specific suffix BGGI against official Renesas documentation to confirm the exact package type and moisture sensitivity level. Confirm availability status as this part number may be subject to discontinuation notices or limited production runs. Ensure compatibility with existing board layouts regarding the 119-pin PBGA footprint and thermal requirements.

Selection Notes

Select this component when a 100 MHz synchronous interface is required for 18-bit wide data paths. Consider the 119-pin PBGA package constraints for PCB space and soldering processes. Evaluate power consumption specifications against system thermal limits, noting the 2.5V core voltage requirement.

Part Context

This device belongs to the 71T75802 family of Zero Bus Turnaround (ZBT) synchronous SRAMs. The family offers various speed grades and packaging options to suit different performance and form factor needs while maintaining consistent functional characteristics and interface protocols across the series.

Replacement Considerations

Check for direct cross-references within the Renesas portfolio such as other speed grades like the S133 or S166 variants. Verify if alternative packages like TQFP are available for the same core functionality if board redesign is permitted.
