71T75902S75PFGI

Overview

The Renesas Electronics Corporation 71T75902S75PFGI 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 supports a maximum clock frequency of 133 MHz with a typical access time of 7.5 ns. It operates within a supply voltage range of 2.375 V to 2.625 V and functions at temperatures between -40°C and +85°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP).

Feature Summary

• Supports high-speed parallel data transfer via Synchronous Single Data Rate interface.
• Enables efficient bus utilization through Zero Bus Turnaround architecture.
• Features low-voltage core operation for reduced power consumption.
• Includes hardware parity generation and checking for data integrity.

Applications

• High-performance networking equipment requiring fast memory buffering.
• Telecommunications infrastructure systems.
• Industrial control systems demanding reliable volatile memory.
• Embedded computing platforms utilizing parallel SRAM interfaces.

Procurement Notes

Verify the specific suffix PFGI to confirm the industrial temperature grade and lead-free packaging status, as variations exist within the family. Confirm current availability status, as this component may be subject to discontinuation notices or limited stock conditions. Ensure compatibility with existing board layouts regarding the 100-TQFP footprint and pin assignments before procurement.

Selection Notes

Select this part when a 1M x 18 organization is required for wide data paths. Choose the 7.5 ns speed grade for applications needing up to 133 MHz operation. Consider the TQFP package if surface mount assembly with moderate pin density is preferred over BGA options. Verify that the 2.5V core voltage aligns with the system's power delivery network capabilities.

Part Context

This component belongs to the Renesas 71T75902 series of ZBT SRAMs. It shares architectural similarities with other members like the 71T75902S85BGG but differs in speed grade and package type. The series is designed for embedded applications requiring high bandwidth and low latency. Note that related parts may have different operating temperature ranges or voltage specifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Check manufacturer obsolescence notices for potential end-of-life status. Evaluate alternative speed grades or packages within the same product family if exact pin-to-pin replacements are unavailable.
