71V35761SA166BGGI

Overview

The 71V35761SA166BGGI is a synchronous single data rate static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 4.5 megabits, organized as 128 kilowords by 36 bits. The device supports parallel interface operations with a maximum clock frequency of 166 MHz and an access time of 3.5 nanoseconds. It operates within a supply voltage range of 3.135 volts to 3.465 volts. The component is housed in a 119-pin plastic ball grid array package measuring 14 by 22 millimeters.

Feature Summary

• Supports high-speed parallel data transfer via a synchronous single data rate interface architecture.
• Features pipelined output structures to maintain throughput at elevated clock frequencies.
• Includes burst counter logic for sequential data access operations.

Applications

• High-performance networking equipment requiring fast buffer memory
• Telecommunications infrastructure systems
• Industrial control systems with strict timing requirements

Procurement Notes

This component has been officially discontinued by the manufacturer. Product change notifications indicate end-of-life status effective January 3, 2024. Verification of current availability requires checking authorized distributors for remaining stock or evaluating qualified replacement parts from the same product family. Ensure compatibility with existing system designs before procurement attempts.

Selection Notes

Designers should consider the 128K x 36 bit organization when mapping memory addresses. The 3.3-volt I/O specification must align with the host processor's voltage levels. The 119-pin PBGA package requires specific PCB layout considerations for thermal management and signal integrity. Verify that the 166 MHz clock capability meets the system's performance targets.

Part Context

This part belongs to the 71V35761S series of synchronous SRAMs. The suffix 'SA' typically denotes specific speed grades or pin configurations within the family. The '166' indicates the maximum operating frequency class. The 'BGGI' suffix specifies the 119-pin PBGA package type and lead-free compliance. This series was designed for applications demanding low latency and high bandwidth data handling.

Replacement Considerations

The IDT71V35761SA166BGGI is listed as a similar alternative part number for this component. Other variants within the 71V35761S family may offer different package options such as TQFP-100 but must be verified for electrical and pinout compatibility.
