71V65803S100BG

Overview

The IDT71V65803S100BG is a 9-Mbit synchronous ZBT SRAM organized as 512K x 18. It operates with a 3.3V core supply and supports clock frequencies up to 100 MHz, achieving a 5 ns access time. The device utilizes a parallel interface and is housed in a 119-ball PBGA package measuring 14x22 mm. Designed for high-performance applications, it features internally synchronized output buffers and single-cycle deselect capabilities.

Feature Summary

• Supports high system speed with 100 MHz clock frequency
• Zero wait state burst operation eliminates dead cycles between write and read operations
• Internally synchronized output buffer enable removes the need for external control signals

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Data storage in industrial automation control systems

Procurement Notes

Verify component authenticity through authorized Renesas or IDT distributors due to potential counterfeit risks. Confirm RoHS compliance status as manufacturing processes may vary by production batch. Check for specific suffix variations that indicate package or temperature range differences. Ensure supply chain stability given the component's lifecycle status.

Selection Notes

Select this part when a 9-Mbit capacity with 5 ns latency is required for synchronous parallel interfaces. Compare against the 71V65803S100BGG8 variant if tape-and-reel packaging is preferred over trays. Consider thermal management requirements for the PBGA package in dense PCB layouts. Evaluate power consumption specifications against system budget constraints.

Part Context

This component belongs to the IDT 71V65803 family of synchronous ZBT SRAMs. It shares architectural similarities with the 71V65703 and 71V65903 series but differs in organization and speed grades. The product line emphasizes low-power performance and high-density storage solutions for embedded applications requiring fast random access.

Replacement Considerations

Public confirmed substitute part numbers include 71V65803S100BGG8.
