71V2546S100BGI8

Overview

The 71V2546S100BGI8 is a synchronous SDR ZBT SRAM IC manufactured by Renesas Electronics Corporation. It features a parallel interface with a storage capacity of 4.5Mb, organized as 128K x 36. The device operates at a clock frequency of 100 MHz with an access time of 5 ns. It utilizes a 119-PBGA (14x22) package and requires a supply voltage between 3.135V and 3.465V. The component supports surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead cycles between read and write operations.
• Internally synchronized output buffer enable removes the need for external OE control.
• 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 RoHS compliance status carefully, as it varies by specific suffix or manufacturing lot date code. Confirm the package type matches the PCB footprint requirements exactly. Check for End-of-Life notices from the manufacturer before finalizing design-in decisions. Ensure voltage levels align with system specifications.

Selection Notes

Select this part when zero bus turnaround performance is required for high-speed data buffering. Compare against other 71V2546 variants based on speed grade and package availability. Verify that the 119-pin BGA form factor fits the assembly constraints. Consider thermal management capabilities within the specified operating temperature range.

Part Context

This component belongs to the 71V2546 family of synchronous SRAMs designed for high-throughput applications. It shares architectural similarities with other ZBT devices but offers specific timing characteristics suited for 100 MHz operation. The series is widely used in embedded systems where deterministic latency is critical.

Replacement Considerations

Consult official substitution lists for compatible parts such as the 71V2546S133BG or 71V2546S150BG8. Verify pinout compatibility and electrical parameter alignment before swapping components.
