71V3556SA150BGGI

Overview

The Renesas Electronics Corporation 71V3556SA150BGGI is a static random-access memory (SRAM) device belonging to the 71V3556SA series. It features a storage capacity of 4.5 Mbit organized as 128K x 36 bits. The component operates with a maximum clock frequency of 150 MHz and an access time of 3.8 ns. It utilizes a parallel interface and synchronous Single Data Rate (SDR) technology, specifically Zero Bus Turnaround (ZBT). The device supports a supply voltage range of 3.135 V to 3.465 V and is housed in a 119-pin PBGA package measuring 14x22 mm.

Feature Summary

• Synchronous SDR ZBT architecture for high-speed data transfer
• Wide 36-bit data organization for efficient bus interfacing
• Surface-mount PBGA packaging for compact board integration

Applications

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

Procurement Notes

Verify current availability status as this product may be subject to discontinuation or limited supply conditions. Confirm that the specific suffix BGGI corresponds to the required 119-PBGA package variant. Ensure compliance with RoHS directives if applicable to your manufacturing standards, noting potential non-compliance for certain variants in this family. Validate lead times through authorized distributors due to potential end-of-life constraints.

Selection Notes

Select this component when a 150 MHz synchronous SRAM with 36-bit width is required. Compare against other speed grades like 100 MHz or 133 MHz variants if lower power consumption is prioritized over speed. Ensure the PCB layout supports the 119-pin PBGA footprint. Verify that the system logic can handle the 3.3V I/O levels and that the 4.5 Mbit capacity meets the application's memory requirements without excessive waste.

Part Context

This part belongs to the Renesas 71V3556SA family of ZBT SRAMs. These devices are designed to replace asynchronous SRAMs in high-speed applications by providing pipelineable performance. The family includes various speed grades and package options, such as the 100 MHz and 133 MHz versions, allowing designers to balance performance and cost. The SA suffix typically denotes specific internal circuitry optimizations for low power and high speed.

Replacement Considerations

Direct substitutes include other speed grades within the same family, such as the 71V3556SA100BGGI or 71V3556SA133BGGI, provided timing constraints allow for slower operation. Cross-brand replacements require careful verification of pin compatibility, voltage levels, and timing parameters.
