71V65803S100PFG

Overview

The Renesas Electronics Corporation 71V65803S100PFG is a synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) integrated circuit. It provides a total storage capacity of 9 Megabits, organized as 512K words by 18 bits. The device supports a maximum clock frequency of 100 MHz with a typical access time of 5 nanoseconds. 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 100-pin Thin Quad Flat Package (TQFP) suitable for surface mount technology.

Feature Summary

• Supports high-speed synchronous data transfer via a parallel interface with Zero Bus Turnaround architecture
• Provides reliable volatile memory storage with fast access times for system caching or buffer applications
• Operates on a standard 3.3V power supply for compatibility with common logic families

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control systems needing reliable volatile memory storage

Procurement Notes

Verify the exact package type and suffix configuration against official Renesas documentation before procurement, as variations exist within the family. Confirm RoHS compliance status and moisture sensitivity levels for your specific manufacturing process requirements. Check current availability as this component may be subject to end-of-life notices or limited stock conditions from authorized distributors.

Selection Notes

Select this part when a 9Mb capacity with 18-bit word width is required in a TQFP-100 package. Ensure the design supports 3.3V logic levels and requires synchronous ZBT SRAM performance at 100MHz. Compare against the 71V65603 series if a 36-bit organization is needed instead of 18-bit. Verify thermal dissipation capabilities for the TQFP package under expected operating loads.

Part Context

This component belongs to the Renesas 71V65803 family of synchronous ZBT SRAMs. It shares architectural similarities with other members like the 71V65803S100BGG8 but differs in packaging and pinout. The family is designed for applications demanding high bandwidth and low latency. Note that related parts may offer different speeds, organizations, or package styles such as BGA variants.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when considering similar SRAM devices from other manufacturers.
