The Quarktwin Technology Ltd. FIFO Memory part number 72221L15PFGI is a synchronous FIFO with a memory organization of 1,024 x 9 bits. It operates with a read/write cycle time of 10 ns and supports independent read and write clocks, allowing for flexible data handling. The device features dual-port architecture with zero fall-through time, making it suitable for high-speed applications such as graphics processing and interprocessor communication. This FIFO includes essential status flags: Empty (EF), Full (FF), and programmable flags for Almost-Empty (PAE) and Almost-Full (PAF), which can be set to any depth, defaulting to Empty+7 and Full-7, respectively. The device is fabricated using advanced submicron CMOS technology and is available in both commercial and industrial temperature ranges, from -40¬8C to +85¬8C. It comes in a 32-pin plastic leaded chip carrier (PLCC) and a 32-pin Thin Quad Flat Pack (TQFP) package. Engineers should note that the lead finish (SnPb) parts are in the end-of-life process, with the last time buy expiring on June 15, 2018.
