71T75802S150PFG

Overview

The Renesas 71T75802S150PFG is a 18 Mbit synchronous static random-access memory (SRAM) organized as 1M x 18. It operates at a maximum clock frequency of 150 MHz with a typical access time of 3.8 ns. The device utilizes a 2.5V core voltage supply ranging from 2.375V to 2.625V and features a parallel interface. It is housed in a 100-pin TQFP package measuring 14x14 mm and supports an operating temperature range of 0°C to 70°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 separate output enable requirements
• Internally synchronized output buffer enable registers address, data, and control signals for pipelined applications
• Supports four-word burst capability in either interleaved or linear modes

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment demanding low-latency memory access
• Industrial automation controllers utilizing ZBT SRAM interfaces
• Consumer electronics with high-speed processing requirements

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm package integrity and moisture sensitivity level handling procedures before assembly. Cross-reference datasheet revisions to ensure compatibility with existing design specifications. Validate electrical parameters against current operational requirements prior to procurement.

Selection Notes

Select this component when zero bus turnaround performance is critical for system throughput. Ensure the 100-pin TQFP footprint matches the target PCB layout constraints. Verify that the 0°C to 70°C commercial temperature range meets environmental conditions. Consider the 1M x 18 organization for specific data width requirements without additional multiplexing.

Part Context

This part belongs to the Renesas 71T75802 family of ZBT synchronous SRAMs. It shares architectural similarities with variants like the 71T75802S133PFG and 71T75802S166BG, differing primarily in speed grade and package type. The family is designed to replace asynchronous memories in high-speed digital designs while maintaining simple parallel interface compatibility.

Replacement Considerations

Publicly confirmed substitute part numbers are not available. The product status is listed as discontinued. Designers should evaluate alternative ZBT SRAM families from other manufacturers or transition to newer memory technologies if long-term supply assurance is required.
