71V65903S85PFG

Overview

The IDT71V65903S85PFG is a 9Mb (512K x 18) synchronous ZBT SRAM IC manufactured by Integrated Device Technology. It operates with a maximum access time of 8.5 ns and supports a clock frequency up to 90 MHz. The device utilizes a 100-pin TQFP package with dimensions of 14 x 20 mm and a height of 1.40 mm. It requires a supply voltage range of 3.135V to 3.465V.

Feature Summary

• Supports high-performance system speeds with zero dead cycles between write and read operations
• Features internally synchronized output buffer enable to eliminate external OE control requirements
• Utilizes a single R/W control pin for simplified interface logic

Applications

• High-speed data buffering in communication systems
• Cache memory applications in embedded processors
• Network equipment data storage

Procurement Notes

Verify the specific suffix PFG against the manufacturer's current datasheet to confirm package type and lead-free status. Ensure the required access speed meets system timing constraints, as other variants exist within the same family. Confirm RoHS compliance if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a 512K x 18 organization is required with synchronous burst capabilities. The ZBT architecture offers superior throughput compared to traditional asynchronous SRAMs. Consider the 100-TQFP package for surface-mount assembly needs where moderate pin count and thermal performance are balanced.

Part Context

This part belongs to the IDT 71V65x03 series of 3.3V Synchronous ZBT SRAMs. The series includes variations such as the 71V65703 (256K x 36) and different speed grades. These devices share common architectural features like flow-through outputs and byte write controls, designed for high-density memory applications.
