71V3556SA150BGGI8

Overview

The 71V3556SA150BGGI8 is a synchronous static random-access memory (SRAM) device manufactured by Renesas Electronics. It features a storage capacity of 4 Mbit, organized as 128K x 36 bits. The component supports a maximum clock frequency of 150 MHz with an access time of 3.8 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and utilizes a parallel interface. The device is housed in a 119-pin PBGA package measuring 14x22 mm.

Feature Summary

• Synchronous Single Data Rate (SDR) architecture for high-speed data transfer
• Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read/write transitions
• Pipelined output structure for improved throughput performance

Applications

• High-performance embedded systems requiring fast memory access
• Network infrastructure equipment
• Industrial control applications

Procurement Notes

Verify the specific suffix BGGI8 against official Renesas documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as sources indicate potential variations. Check current production lifecycle status, as related models in this series have been marked as obsolete or end-of-life. Ensure moisture sensitivity level requirements are met for surface mount assembly processes.

Selection Notes

Select this component when a 128K x 36 organization is required with synchronous operation at 150 MHz. Compare against other variants in the 71V3556SA series based on speed grade and I/O voltage compatibility. Ensure the 119-PBGA footprint matches the target PCB design constraints. Verify that the 3.3V core voltage aligns with the system power architecture.
