72T7285L4-4BB

FIFOs Memory Overview

The Renesas 72T7285L4-4BB is a TeraSync First-In-First-Out (FIFO) memory device featuring a 16K x 72 organization. It operates with independent read and write clocks, supporting simultaneous data transfer. The component utilizes a 2.5V supply voltage and offers flexible bus-matching capabilities for x72, x36, or x18 data flows. It includes programmable flags for status monitoring and supports both IDT Standard mode and First Word Fall Through (FWFT) timing modes.
