Procurement Notes

Verify the exact suffix designation during procurement, as the PFG8 variant may differ in packaging or compliance status compared to the PFI version listed in available records. Confirm RoHS compliance requirements, as some variants in this series are noted as non-compliant. Check current availability status, as the base product line may be discontinued or subject to limited stock conditions depending on the specific manufacturing batch and distributor inventory.

Selection Notes

Select this component when a 4.5Mb synchronous SRAM with 18-bit word width is required for parallel bus architectures. Ensure the design accommodates the 3.3V nominal supply voltage range and the 100-pin footprint constraints. Verify that the system timing allows for the 3.8ns access window at the target 150MHz operating frequency. Consider thermal management capabilities if operating near the upper temperature limits of the specified range.

Part Context

This part belongs to the IDT71V3578 family of synchronous SRAM devices, which are engineered for applications demanding high bandwidth and low latency. The manufacturer utilizes this nomenclature to denote specific speed grades and package configurations within the broader memory portfolio. These components serve as critical temporary storage elements in complex digital logic designs where rapid read/write cycles are essential for system performance.
