71V3556SA150BG8

Overview

The 71V3556SA150BG8 is a synchronous single data rate zero bus turnaround static random access memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5 megabits organized as 128 kilowords by 36 bits. The device supports a maximum clock frequency of 150 MHz with an access time of 3.8 nanoseconds. It operates on a single 3.3-volt power supply within the range of 3.135 to 3.465 volts and is housed in a 119-pin plastic ball grid array package measuring 14 by 22 millimeters.

Feature Summary

• Synchronous SDR architecture with zero bus turnaround capability for efficient bidirectional data transfer
• High-speed parallel interface supporting up to 150 MHz clock frequencies
• Single 3.3V power supply operation with dedicated VCCQ control for I/O levels

Applications

• High-performance processor secondary cache systems
• Network routing and switching buffer memory
• Digital signal processing pipeline buffering

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package marking alignment with the 119-PBGA specification. Check RoHS compliance documentation as the product may not meet current environmental standards. Validate moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required for high-throughput applications. Ensure the design accommodates the specific 119-ball BGA footprint dimensions. Verify that the system logic supports the 3.3V I/O voltage requirements and timing constraints associated with the 150 MHz operational speed.

Part Context

This part belongs to the 71V3556 family of synchronous ZBT SRAMs from Renesas, formerly IDT. The family offers various speed grades and packaging options including PBGA and CABGA configurations. The 71V3556SA150BG8 specifically denotes the 150 MHz speed bin within the SA series using the BG8 trailing suffix for the tape and reel packaging format.
