71T75802S133BGGI8

Memory IC Overview

The 71T75802S133BGGI8 is a 18 Mbit synchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a parallel interface with a data organization of 1M x 18 bits and operates at a maximum clock frequency of 133 MHz. The device utilizes Zero Bus Turnaround (ZBT) technology to eliminate dead cycles between read and write operations. It requires a core supply voltage range of 2.375V to 2.625V and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a 119-pin plastic ball grid array (PBGA) package measuring 14x22 mm.

Memory IC Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates bus turnaround dead cycles between read and write transitions.
• Fully pipelined design with internally synchronized output buffer enable for high-speed system performance.
• Single R/W control pin simplifies interface logic by removing the need for separate output enable control.
• Supports individual byte write capabilities via BW1-BW4 control signals for efficient data management.

Memory IC Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment utilizing ZBT SRAM interfaces
• Industrial control applications operating within extended temperature ranges

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels, as this part number may be subject to discontinuation notices. Confirm that the specific suffix matches the required package type and temperature grade. Ensure compliance with RoHS3 standards and check for any product change notifications regarding labeling or packaging updates prior to integration into production designs.

Memory IC Selection Notes

Select this component when a 18 Mbit capacity with a 133 MHz synchronous interface is required. The 119-PBGA package is suitable for space-constrained surface-mount applications. Consider the -40°C to +85°C temperature range for industrial environments. Verify that the 2.5V I/O voltage compatibility aligns with the host processor's signaling levels before finalizing the design.

Memory IC Part Context

This device belongs to the 71T75802 series of ZBT synchronous SRAMs. The series offers various speed grades and package options, including TQFP and PBGA configurations. The 71T75802 family is designed to replace asynchronous SRAMs in high-speed applications by providing pipeline depth and zero wait-state operation without requiring complex timing adjustments.

Memory IC Replacement Considerations

Consult official Renesas documentation for verified substitute part numbers. Alternative options within the same series may include different speed grades or package types, such as the 71T75802S166BG8, provided they meet the electrical and physical requirements of the existing design.
