71V65803S133PFGI8

Overview

The 71V65803S133PFGI8 is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 9 Mbit, organized as 512K x 18 bits. The device supports a maximum clock frequency of 133 MHz with an access time of 4.2 ns. It operates on a single 3.3V power supply within a voltage range of 3.135V to 3.465V. The component utilizes a parallel interface and is housed in a 119-pin PBGA package measuring 14x22 mm. It is designed for high-performance data buffering applications requiring fast read/write cycles.

Feature Summary

• Supports synchronous Single Data Rate (SDR) operation with Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during direction changes.
• Provides high-speed data transfer capabilities through a 133 MHz clock frequency and rapid 4.2 ns access time.
• Features pipelined architecture optimized for efficient data throughput in complex digital systems.

Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications infrastructure for signal processing memory
• Industrial automation systems needing reliable data storage

Procurement Notes

Verify the specific suffix PFGI8 against official Renesas documentation to confirm the exact package type and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the 119-PBGA(14x22) configuration. Check for any recent Product Change Notifications regarding lead content or RoHS compliance status before finalizing procurement plans.

Selection Notes

Select this component when a 9Mbit synchronous SRAM with a 18-bit word width is required. The 133 MHz speed class suits applications demanding low latency. Compare pinout and electrical characteristics against alternative packages like TQFP if space constraints differ. Confirm that the 3.3V I/O levels match the system logic requirements.

Part Context

This part belongs to the 71V65803 series of synchronous ZBT SRAMs from Renesas. It shares architectural similarities with other members of the family but differs in organization and package. The series is designed for embedded applications where high-speed memory access is critical. It represents a transition point in Renesas's SRAM portfolio offering dense memory in compact surface-mount packages.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-references with IDT-branded equivalents only if explicitly documented by the manufacturer. Do not assume functional equivalence with asynchronous SRAMs due to differing control signals.
