71V65703S80PFGI

Overview

The 71V65703S80PFGI is a 9-Mbit synchronous static random-access memory (SRAM) organized as 256K x 36. It utilizes Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read-write transitions. The device operates with a maximum clock frequency of 80 MHz and features a typical access time of 8 ns. It supports a supply voltage range of 3.135V to 3.465V and is housed in a 119-pin PBGA package measuring 14x22 mm.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead bus cycles between read and write operations.
• Flow-through output configuration provides data without an output register for low latency.
• Includes address, data-in, and control signal registers for synchronous operation.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory systems in embedded controllers
• Network switching applications requiring rapid data turnaround

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Cross-reference pinouts with official datasheets to ensure compatibility with existing PCB layouts.

Selection Notes

Select this component for designs requiring high-density 36-bit wide memory interfaces with minimal turnaround latency. Ensure the system clock does not exceed 80 MHz. Verify that the 119-pin PBGA footprint matches the target board design constraints.

Part Context

This part belongs to the Renesas 71V65703 family of ZBT SRAMs. It shares architectural similarities with other members like the 71V65703S85BQGI but differs in speed grade and package type. The series is designed for applications demanding high throughput and efficient bus utilization.

Replacement Considerations

The 71V65703S85BQGI is a documented alternative within the same family, offering similar functionality with different speed and packaging characteristics.
