... DESCRIPTION The L8C201, L8C202, L8C203, and L8C204 are dual-port First-In/First- Out (FIFO) memories. The FIFO memory products are organized as: L8C201 — 512 x 9-bit L8C202 — 1024 x 9-bit L8C203 — 2048 x 9-bit L8C204 — 4096 x 9-bit Each device utilizes a special algorithm that loads and empties data on a first- in/first-out basis ...

... If the read pointer is not moved after Reset (RS), the Full Flag (FF) will go LOW after 512 writes for the L8C201, 1024 writes for the L8C202, 2048 writes for the L8C203, and 4096 writes for the L8C204. ...

... FIFOs. Care must be taken to assure that the appropriate flag is monitored by each system (i.e monitored on the device when W is used monitored on the device when R is used). Both Depth Expansion and Width Expansion may be used in this mode. 3 L8C201/202/203/204 FIFO Products 03/04/99–LDS.8C201/2/3/4-H ...

... Long high-inductance leads that cause sup- ply bounce must be avoided by bringing the and ground planes directly up to the V CC contactor fingers. A 0.01 µF high frequency capacitor is also required between V ground. To avoid signal reflections, proper terminations must be used L8C201/202/203/204 F 2a. IGURE R 480 OUTPUT + SLSH ...
