71V2546S100BG8

Overview

The 71V2546S100BG8 is a 4.5Mb parallel synchronous SRAM manufactured by Renesas Electronics Corporation, organized as 128K x 36. It operates at a clock frequency of 100 MHz with an access time of 5 ns. The device utilizes a 119-PBGA (14x22) package and requires a supply voltage between 3.135V and 3.465V. Designed for surface mount installation, it supports a commercial operating temperature range of 0°C to 70°C.

Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead cycles during bus turnaround between read and write operations.
• Internally synchronized output buffer enable removes the requirement for external OE control signals.
• Positive clock-edge triggered registers for address, data, and control signals support fully pipelined applications.

Applications

• High-performance processor secondary cache systems
• Network infrastructure equipment requiring low-latency memory
• Industrial automation controllers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as this variant may differ from lead-free alternatives. Validate package dimensions and pinout compatibility before finalizing procurement plans.

Selection Notes

Select this model when ZBT performance is required in a BGA footprint. Compare against the 71V2546S100PFG if TQFP packaging is preferred. Ensure system design accommodates the 3.3V power supply constraints and commercial temperature limits specified for this part number.

Part Context

This component belongs to the 71V2546 family of high-speed synchronous SRAMs. It shares architectural similarities with other variants like the 71V2546S150BG8 but differs in speed grade and package type. The series is designed for applications demanding fast data throughput without bus turnaround delays.

Replacement Considerations

Public confirmed substitute part numbers include 71V2546S133PFG and 71V2546S150PFG. Verify electrical specifications and package compatibility before substitution.
