71V3556SA166BQ

Overview

The Renesas 71V3556SA166BQ is a 4.5 Mbit synchronous static random-access memory (SRAM) organized as 128K x 36. It operates with a maximum clock frequency of 166 MHz and features a typical access time of 3.5 ns. The device utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. It is housed in a 165-pin CABGA package measuring 13x15 mm.

Feature Summary

• Supports high-speed data transfer via a 166 MHz synchronous clock interface
• Provides fast 3.5 ns access times for efficient system performance
• Features a 36-bit bus width to accommodate wide data paths

Applications

• High-performance computing systems requiring rapid data access
• Network infrastructure equipment utilizing wide data buses
• Industrial control systems needing reliable synchronous memory

Procurement Notes

Verify the exact suffix against official documentation, as variations like BQGI8 or BQ8 indicate specific packaging or regional compliance differences. Confirm current availability status directly with the manufacturer or authorized distributors, as lead times and stock levels fluctuate. Ensure the selected variant matches your required operating temperature range and moisture sensitivity level specifications before finalizing orders.

Selection Notes

Select this component when a 36-bit data width is required for synchronous applications. Compare the 166 MHz speed grade against other variants in the series if lower frequencies suffice for cost reduction. Ensure the PCB layout supports the 165-CABGA package dimensions and that the power supply design accommodates the specified voltage range and current consumption limits.

Part Context

This part belongs to the 71V3556SA166 family of synchronous SRAMs from Renesas Electronics. These devices are designed for applications demanding high bandwidth and low latency. The family typically includes variants with different access speeds and package options, allowing designers to balance performance requirements with physical space constraints in their electronic designs.

Replacement Considerations

The IDT71V3556S166BQ8 is listed as an alias for this component. Verify pin compatibility and electrical specifications before substitution. Other family members may offer different speeds but require validation of timing parameters.
