71V65803S133BQG

Overview

The 71V65803S133BQG is a 9 Mbit Synchronous ZBT SRAM manufactured by Renesas Electronics Corporation. It features a parallel interface with a memory organization of 512K x 18 bits. The device supports a maximum clock frequency of 133 MHz and offers an access time of 4.2 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and is housed in a 165-CABGA (13x15) package. The component is designed for surface mount installation and functions within a temperature range of 0°C to 70°C.

Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead bus cycles during read/write transitions.
• Pipelined outputs support high-speed burst data transfer operations.
• Integrated registers for address, data-in, and control signals enhance synchronization.

Applications

• High-performance embedded systems requiring fast random access
• Network infrastructure equipment
• Industrial automation controllers

Procurement Notes

Verify the specific suffix BQG against official datasheets to confirm pinout compatibility, as packaging variations exist within the 71V65803 family. Confirm RoHS compliance status, as some variants in this series are non-compliant. Check for End-of-Life notices, as production may be discontinued. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a 512K x 18 organization is required rather than the 256K x 36 configuration found in other family members like the 71V65603. The 133 MHz speed grade suits applications needing lower latency than the 100 MHz variants. Verify that the 165-pin CABGA package fits the target PCB footprint constraints compared to the 119-pin PBGA option.

Part Context

This part belongs to the IDT/Renesas 71V65xxx series of 3.3V synchronous static random-access memories. These devices utilize Zero Bus Turnaround technology to maximize throughput. The series includes various speed grades and organizations, such as 256K x 36 and 512K x 18, catering to different bandwidth and density requirements in digital signal processing and networking.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model were not identified in the provided documentation. Users should consult manufacturer obsolescence notices for potential cross-references or alternative packages within the same product line.
