DESCRIPTION:
The IDT72V3640/72V3650/72V3660/72V3670/72V3680/72V3690 are
exceptionally deep, high speed, CMOS First-In-First-Out (FIFO) memories
with clocked read and write controls and a flexible Bus-Matching x36/x18/x9
data flow. These FIFOs offer several key user benefits:
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 1 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
