71V65703S75PFGI

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 75 MHz and provides an access time of 4.2 nanoseconds. The component supports parallel interface communication and functions within a supply voltage range of 3.135 volts to 3.465 volts. It is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x20 millimeters.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead bus cycles between read and write operations.
• Flow-through output configuration allows data to appear immediately without additional latency registers.
• Internal address, data-in, and control signal registers enable efficient burst mode operation.
• Supports single-cycle data transfer for four cycles of data per presented address.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers
• Signal processing applications requiring low-latency memory access

Procurement Notes

Verify the specific suffix PFGI to confirm the 100-TQFP package type and lead-free status. Confirm RoHS3 compliance and moisture sensitivity level requirements for your assembly process. Check current manufacturing status as this series may have end-of-life notifications. Ensure voltage levels match your system's 3.3V nominal supply specifications.

Selection Notes

Select this component when ZBT performance is required to maximize throughput in synchronous designs. The 256K x 36 organization suits wide-data-path applications. Compare access times against other variants like the S85 or S100 if higher speed is needed. Consider the TQFP package constraints for PCB layout and thermal management compared to BGA options.

Part Context

This part belongs to the 71V65703 family of high-performance synchronous SRAMs. The family shares common ZBT architecture and flow-through characteristics. Variants differ primarily in access speed and package type. The 71V65703 series is designed for applications demanding high bandwidth and minimal wait states in complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers include 71V65703S80PFGI and 71V65703S85PFGI. These alternatives offer different access speeds while maintaining the same package and pinout compatibility.
