71V3556SA100BQG

Overview

The Renesas Electronics Corporation 71V3556SA100BQG is a synchronous single data rate zero bus turnaround (ZBT) static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 4.5 megabits, organized as 128 kilowords by 36 bits. The device operates with a maximum clock frequency of 100 MHz and features a typical access time of 5 nanoseconds. It requires a supply voltage range between 3.135 volts and 3.465 volts. The component utilizes a parallel interface and is housed in a 165-contact cavity ball grid array package measuring 13 by 15 millimeters.

Feature Summary

• Synchronous operation utilizing a single data rate architecture for high-speed data transfer
• Zero bus turnaround capability to minimize latency during read-to-write or write-to-read transitions
• Parallel interface supporting wide 36-bit data paths for efficient system integration

Applications

• High-performance networking equipment requiring fast buffer memory
• Telecommunications infrastructure systems
• Industrial control applications needing rapid data processing

Procurement Notes

Verify the specific suffix BQG against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as some variants may not meet current environmental standards. Check for active discontinuation notices or end-of-life notifications prior to finalizing procurement plans.

Selection Notes

Select this component when a 36-bit wide data path is required for synchronous memory applications. Ensure the design supports the specified 3.3-volt I/O levels and the 165-ball BGA footprint constraints. Verify that the system timing requirements align with the 5-nanosecond access specification at the target operating frequency.
