These FIFOs offer several key userbenefits: • Flexible x36/x18/x9 Bus-Matching on both read and write ports • The period required by the retransmit operation is fixed and short. • The first word data latency period, from the time the first word is written to an empty FIFO to the time it can be read, is fixed and short. • Asynchronous/Synchronous translation on the read or write ports • High density offerings up to 4 Mbit Bus-Matching Sync FIFOs are particularly appropriate for network, video, telecommunications,datacommunicationsandotherapplicationsthatneedto buffer large amounts of data and match busses of unequal sizes. Each FIFO has a data input port (Dn) and a data output port (Qn), both of which can assume either a 36-bit, 18-bit or a 9-bit width as determined by the state of external control pins Input Width (IW), Output Width (OW), and Bus- Matching (BM) pin during the Master Reset cycle. TheinputportcanbeselectedaseitheraSynchronous(clocked)interface, or Asynchronous interface. During Synchronous operation the input port is controlledbyaWriteClock(WCLK)inputandaWriteEnable( WEN)input. Data present on the Dn data inputs is written into the FIFO on every rising edge of NOTE: 1. DNC = Do Not Connect.
