71T75802S100BGGI8

Overview

The Renesas 71T75802S100BGGI8 is a synchronous static random-access memory (SRAM) integrated circuit with an 18 Mbit capacity, organized as 1M x 18. It operates at a clock frequency of 100 MHz with a 5 ns access time. The device utilizes a 2.375V to 2.625V supply voltage and features a 119-pin PBGA package measuring 14x22 mm. Designed for surface mount applications, it supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead cycles between read and write operations.
• Single R/W control pin simplifies interface logic by removing the need for separate output enable signals.
• Internally synchronized output buffer enable registers address and data signals for pipelined performance.

Applications

• High-speed digital signal processing systems
• Network infrastructure equipment requiring low-latency buffering
• Industrial automation controllers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Review official product change notices for any packaging or labeling updates that may affect handling procedures.

Selection Notes

Select this component when a 100 MHz synchronous SRAM with ZBT technology is required. Ensure the design accommodates the 119-pin BGA footprint and 2.5V core voltage constraints. Consider thermal management capabilities within the specified industrial temperature range during board layout.

Part Context

This part belongs to the 71T75802 family of high-performance synchronous SRAMs. It shares architectural similarities with other variants in the series but is distinguished by its specific 100 MHz speed grade and 119-pin BGA package configuration.

Replacement Considerations

Consult official obsolescence notices for qualified substitute part numbers. Verify electrical compatibility and pinout alignment before transitioning to alternative components.
