71V65703S75PFG8

Overview

The 71V65703S75PFGI is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 9 megabits, organized as 256 kilowords by 36 bits. The device utilizes Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read-write transitions. It operates with a clock frequency of 100 MHz and an access time of 5 nanoseconds. The supply voltage range is specified from 3.135 volts to 3.465 volts. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x20 millimeters. It supports parallel interface communication and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead bus cycles between read and write operations.
• Flow-through output architecture provides immediate data availability without output registers.
• Internal address, data-in, and control signal registers enable efficient burst mode operation.
• Synchronous single data rate (SDR) interface ensures high-speed data transfer.

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment for packet processing
• Industrial automation controllers needing rapid memory access
• Telecommunications base stations for signal processing

Procurement Notes

Verify the exact suffix designation on the component marking, as the PFGI package variant differs from the requested PFG8. Confirm RoHS compliance status, as older batches may not meet current environmental standards. Check for end-of-life notices or obsolescence declarations from the manufacturer before finalizing procurement plans. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements.

Selection Notes

Select this component when zero bus turnaround latency is critical for system performance. The 256K x 36 organization suits applications requiring wide data paths. Verify that the 3.3V I/O levels match the host processor interface. Consider the 100-TQFP package constraints for PCB space and thermal management. Evaluate if the synchronous interface complexity aligns with the design capabilities.

Part Context

This part belongs to the 71V65xxx family of ZBT SRAMs designed for high-speed parallel memory applications. The family emphasizes reduced wait states through internal pipelining and register structures. These devices are engineered to replace asynchronous SRAMs in high-frequency digital designs. The specific model represents a standard density option within the broader product line.

Replacement Considerations

The 71V65703S80PFGI is a documented substitute offering similar functionality with slightly different timing characteristics. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part meets the same environmental and packaging requirements.
