71V25761S166BGI

Memory IC Overview

The Renesas Electronics Corporation 71V25761S166BGI is a synchronous single data rate static random access memory (SRAM) integrated circuit. It features a storage capacity of 4.5 Mbit organized as 128K x 36 bits. The device supports a maximum clock frequency of 166 MHz with an access time of 3.5 ns. It operates on a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a 119-pin plastic ball grid array (PBGA) package measuring 14x22 mm, suitable for surface mount installation.

Memory IC Feature Summary

• Supports high-speed synchronous burst operations at frequencies up to 166 MHz
• Provides wide 36-bit data bus width for efficient data transfer
• Utilizes a compact 119-pin PBGA surface-mount package

Memory IC Applications

• High-performance networking equipment
• Telecommunications infrastructure systems
• Industrial control applications requiring fast memory access

Memory IC Procurement Notes

Verify the specific suffix BGI to confirm the 119-pin PBGA packaging configuration. Ensure compatibility with the required 3.3 V power supply rails within the specified tolerance range. Confirm that the moisture sensitivity level and lead-free status meet your assembly process requirements before ordering.

Memory IC Selection Notes

Select this component when a 36-bit data path is necessary for system architecture. It is appropriate for designs requiring synchronous operation at 166 MHz. Consider the 119-pin PBGA footprint during PCB layout planning. Verify thermal management capabilities for the SMD installation style.

Memory IC Part Context

This part belongs to the 71V25761S family of synchronous SRAM devices from Renesas. It shares the same memory organization and core functionality as other variants in the series but differs in speed grade and physical packaging. The 166 MHz variant offers faster performance compared to lower-frequency models like the 100 MHz version.

Memory IC Replacement Considerations

The IDT71V25761S166BGI is a confirmed substitute part number for this component. Both parts share identical electrical specifications and pin configurations.
