71T75802S150BGGI8

Overview

The Renesas 71T75802S150BGGI8 is a synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) integrated circuit. It provides an 18 Mbit storage capacity organized as 1M x 18 bits. The device operates with a maximum clock frequency of 150 MHz and features a typical access time of 3.8 ns. It utilizes a parallel interface and requires a supply voltage range of 2.375V to 2.625V. The component is housed in a 119-PBGA package measuring 14x22 mm, designed for surface mount installation.

Feature Summary

• Supports Synchronous Single Data Rate (SDR) operation with Zero Bus Turnaround (ZBT) technology for high-speed data transfer.
• Integrates a burst counter and pipelined outputs to optimize memory access efficiency.
• Features a 1M x 18 bit organization suitable for wide data bus applications.

Applications

• High-performance embedded systems requiring fast random access memory
• Network infrastructure equipment and telecommunications hardware
• Industrial control systems and automation controllers

Procurement Notes

Verify the specific suffix 'GI8' against official Renesas documentation to confirm temperature grade and packaging details, as standard 'BG8' variants may differ. Confirm RoHS compliance status, as some sources indicate non-compliance for this series. Check current lifecycle status, as discontinuation notices exist for related 71T75802 models. Ensure compatibility with existing PCB footprints for the 119-PBGA (14x22) package before procurement.

Selection Notes

Select this component when a 150 MHz synchronous SRAM with 18-bit width is required. Compare access times and power consumption against other ZBT SRAM options if lower latency or reduced current draw is critical. Ensure the design supports the 2.5V core voltage and appropriate I/O levels. Consider the 119-PBGA package constraints regarding board space and thermal management during selection.

Part Context

This part belongs to the IDT/Renesas 71T75802 family of 2.5V Synchronous ZBT SRAMs. The family includes variants with different speeds (e.g., 133 MHz, 166 MHz, 200 MHz) and packages (TQFP, PBGA). The 71T75802 series is designed for applications demanding high bandwidth and low latency, serving as a drop-in replacement for older asynchronous SRAMs in many legacy designs.

Replacement Considerations

Direct substitutes include other speed grades within the 71T75802 family, such as 71T75802S133BGGI8 or 71T75802S166BGGI8, provided timing requirements allow. Verify pinout compatibility and electrical specifications before substitution. Cross-reference with Renesas PCN documents for any functional changes in newer revisions.
