71V35761SA183BGI

Overview

The Renesas Electronics Corporation 71V35761SA183BGI is a synchronous single data rate 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 supports a maximum clock frequency of 183 MHz with a typical access time of 3.3 nanoseconds. It operates within a supply voltage range of 3.135 volts to 3.465 volts and is housed in a 119-pin plastic ball grid array package measuring 14 by 22 millimeters. The component is designed for surface mount installation.

Feature Summary

• Synchronous parallel interface architecture supporting high-speed data transfer
• Pipeline burst mode capability for efficient sequential data access
• Wide 36-bit data bus width for high-bandwidth applications

Applications

• High-performance networking equipment buffer memory
• Telecommunications system data caching
• Industrial control system temporary data storage

Procurement Notes

Verify the specific suffix designation carefully, as variants such as BGGI or BG8 may differ in temperature rating or packaging. Confirm RoHS compliance status prior to integration, as certain revisions may not meet current environmental standards. Check for end-of-life notifications or product discontinuance notices from the manufacturer to ensure long-term supply availability for production cycles.

Selection Notes

Select this component when a wide 36-bit data path is required for synchronous memory operations. Ensure the design accommodates the 3.3-volt I/O logic levels and the specific thermal requirements of the PBGA package. Compare against alternative SRAM families if lower pin counts or different organizational structures better fit the board space constraints.
