FUNCTIONAL BLOCK DIAGRAM
FEATURES:
Two independent FIFO memories for fully bidirectional data
transfers
256 x 18 x 2 organization (IDT72605)
512 x 18 x 2 organization (IDT72615)
Synchronous interface for fast (20ns) read and write cycle times
Each data port has an independent clock and read/write control
Output enable is provided on each port as a three-state control
of the data bus
Built-in bypass path for direct data transfer between two ports
Two fixed flags, Empty and Full, for both the A-to-B and the B-
to-A FIFO
Programmable flag offset can be set to any depth in the FIFO
The synchronous BiFIFO is packaged in a 64-pin TQFP (Thin
Quad Flatpack) and 68-pin PLCC
Industrial temperature range (–40
°°°°°C to +85°°°°°C)
Green parts available, see ordering information
DESCRIPTION:
The IDT72605 and IDT72615 are very high-speed, low-power bidirec-
tionalFirst-In,First-Out(FIFO)memories,withsynchronousinterfaceforfast
read and write cycle times. The SyncBiFIFO is a data buffer that can store
orretrieveinformationfromtwosourcessimultaneously.TwoDual-PortFIFO
memory arrays are contained in the SyncBiFIFO; one data buffer for each
direction.
The SyncBiFIFO has registers on all inputs and outputs. Data is only
transferred into the I/O registers on clock edges, hence the interfaces are
synchronous. EachPorthasitsownindependentclock.Datatransferstothe
I/O registers are gated by the enable signals. The transfer direction for each
portiscontrolledindependentlybyaread/writesignal. Individualoutputenable
signals control whether the SyncBiFIFO is driving the data lines of a port or
whether those data lines are in a high-impedance state.
Bypass control allows data to be directly transferred from input to output
registerineitherdirection.
