71V2546S150BG8

Overview

The 71V2546S150BG8 is a 4.5Mb synchronous single data rate zero bus turnaround SRAM manufactured by Renesas Electronics Corporation. It features a parallel interface with a clock frequency of 150 MHz and an access time of 3.8 ns. The device is organized as 128K x 36 bits and operates within a supply voltage range of 3.135V to 3.465V. It is housed in a 119-PBGA (14x22) surface-mount package and supports commercial operating temperatures from 0°C to 70°C.

Feature Summary

• Supports synchronous single data rate operation with zero bus turnaround capability for efficient data transfer.
• Provides high-speed parallel memory access suitable for demanding system architectures.

Applications

• High-performance computing systems requiring fast cache memory
• Network infrastructure equipment
• Industrial automation control units

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as this specific variant may not meet current environmental standards. Validate package integrity upon receipt, as moisture sensitivity level 3 requires proper handling. Ensure design compatibility with the specified 3.3V power domain before integration.

Selection Notes

Select this component when a 150 MHz synchronous SRAM with a 128K x 36 organization is required. Consider the 119-PBGA package constraints for PCB layout. Evaluate thermal performance within the commercial temperature range. Compare against alternative speed grades if system timing allows for lower frequencies.

Part Context

This part belongs to the 71V2546 family of synchronous SRAMs, which offers various speed grades and package options. The 'S' suffix typically denotes specific speed binning, while 'BG8' indicates the BGA package type. This family is designed for applications needing high-bandwidth memory solutions with low latency characteristics.

Replacement Considerations

Check for 71V2546S133BG or 71V2546S100PFG as potential functional substitutes with different speeds or packages. Verify pinout compatibility and electrical specifications before substitution.
