FIFOs Memory Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors or existing stock. Verify RoHS compliance status and moisture sensitivity levels before procurement, as these attributes are critical for handling and soldering processes in current manufacturing environments.

FIFOs Memory Selection Notes

Select this part when a deep, high-speed synchronous FIFO with 18-bit width is required. Ensure the design accommodates the 3 V to 3.6 V operating voltage and 64-TQFP package constraints. Consider the 15 ns access time and 66.7 MHz clock limit for timing closure. Due to its obsolete status, evaluate long-term supply chain risks and potential redesign requirements for future production runs.

FIFOs Memory Part Context

The 72V285L15TFI8 belongs to the IDT 72V285 series of synchronous FIFOs. This series is characterized by exceptionally deep memory depths and high-speed performance using CMOS technology. The specific suffix 'L15' denotes the 15 ns speed grade, while 'TFI8' indicates the TQFP-64 package type. These devices are engineered for demanding buffering tasks in high-performance digital systems.

FIFOs Memory Replacement Considerations
