71V65803S100PFG

Overview

The IDT71V65803S100PFG is a ZBT SRAM with a 9Mb capacity organized as 512K x 18. It features a 5ns access time and supports a maximum clock frequency of 100 MHz. The device operates on a 3.3V power supply with 3.3V I/O levels. It utilizes a parallel interface and is housed in a 100-pin TQFP package measuring 14 x 20 mm.

Feature Summary

• ZBT technology eliminates dead cycles between write and read operations
• Internal burst counter supports interleaved or linear burst modes
• Self-timed write cycle with global write control

Applications

• High-speed data buffering in communication systems
• Cache memory for network processors
• Digital signal processing applications

Procurement Notes

Verify the specific suffix PFG to confirm the 100-pin TQFP package and lead-free status. Confirm RoHS compliance and moisture sensitivity level requirements against your assembly process specifications before procurement.

Selection Notes

Select this component when a 512K x 18 organization is required with 100 MHz synchronous performance. Ensure the design accommodates 3.3V logic levels and utilizes the TQFP-100 footprint for surface mount integration.

Part Context

This part belongs to the IDT 71V65803 family of Zero Bus Turnaround (ZBT) Synchronous SRAMs. These devices are designed for high-performance embedded applications requiring fast random access and low latency without the complexity of pipelined architectures.

Replacement Considerations

Check for equivalent parts within the 71V65803 series that match the 100MHz speed grade and TQFP-100 package. Verify pin compatibility and electrical parameters for direct substitution.
