71V65703S85PFGI

Overview

The 71V65703S85PFGI is a synchronous single data rate zero bus turnaround (ZBT) static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It offers a storage capacity of 9 megabits organized as 256 kilowords by 36 bits. The device operates with an access time of 8.5 nanoseconds and supports clock frequencies up to 117 MHz. It functions within a supply voltage range of 3.135 volts to 3.465 volts and is housed in a 100-pin thin quad flatpack package measuring 14x20 millimeters.

Feature Summary

• Implements Zero Bus Turnaround technology to eliminate dead bus cycles during read-to-write or write-to-read transitions, enhancing system throughput efficiency.
• Features flow-through output architecture without output data registers, allowing direct data availability upon address presentation.
• Includes internal registers for address, data-in, and control signals to synchronize operations with the system clock.
• Supports burst mode operation to provide four cycles of data for a single address presented to the SRAM.

Applications

• High-performance embedded systems requiring fast parallel memory access
• Network infrastructure equipment utilizing ZBT SRAM interfaces
• Industrial control applications needing reliable synchronous memory solutions

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS3 compliance status and check for specific manufacturing date codes relevant to your production timeline. Ensure proper handling procedures are followed given the moisture sensitivity level classification. Validate pin compatibility with existing PCB layouts before finalizing procurement decisions.

Selection Notes

Select this component when designing systems that require high-speed parallel data transfer with minimal latency penalties during bus direction changes. Consider the 36-bit data width suitability for wide-bus architectures. Evaluate thermal performance requirements against the specified operating temperature range. Compare alternative packages if space constraints differ from the standard TQFP form factor.

Part Context

This part belongs to the 71V65703 family of synchronous ZBT SRAMs designed for high-speed data processing applications. It shares architectural similarities with other members like the 71V65603 series but offers optimized timing characteristics. The product line emphasizes reduced bus turnaround times compared to traditional asynchronous or pipelined SRAMs.

Replacement Considerations

Publicly confirmed substitute part numbers include 71V65703S85BQGI and 71V65703S85PFGI8. Verify pinout compatibility and electrical specifications before substitution. Note that package variations may require adapter solutions or PCB redesigns.
