71V3556SA150BQ

Overview

The 71V3556SA150BQ is a synchronous single data rate zero bus turnaround SRAM manufactured by Renesas Electronics. It features a 4.5 Mbit capacity organized as 128K x 36 bits. The device supports a maximum clock frequency of 150 MHz with an access time of 3.8 ns. It operates on a 3.3V power supply ranging from 3.135V to 3.465V and is housed in a 165-CABGA package measuring 13x15 mm. The component is designed for parallel interface applications.

Feature Summary

• Synchronous SDR architecture enabling high-speed data transfer
• Zero bus turnaround capability for efficient read/write transitions
• Parallel interface supporting standard system integration

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment
• Industrial automation controllers

Procurement Notes

Verify the exact suffix designation, as official documentation lists 71V3556SA150BQ8. Confirm RoHS compliance status, as specific variants may not meet current environmental standards. Check for end-of-life notifications or product change notices prior to finalizing procurement decisions.

Selection Notes

Select this component when a 150 MHz synchronous SRAM with a 36-bit width is required. Ensure the design accommodates the 165-CABGA package dimensions. Verify that the system voltage aligns with the specified 3.3V operating range and that thermal management suits the commercial temperature grade.

Part Context

This part belongs to the 71V3556 family of synchronous SRAMs. Variants within this series differ primarily in clock speed, access time, and packaging options. The SA suffix typically denotes specific performance grades or pin configurations within the broader product line.

Replacement Considerations

Check for direct substitutes such as the 71V3556SA100BQ8 or 71V3556SA133BQI8. These alternatives offer similar architectures but with different clock frequencies and access times. Verify pin compatibility and electrical specifications before substitution.
