IDT723612
CMOS SYNCBiFIFOTM 64 x 36 x 2
COMMERCIAL AND INDUSTRIAL
TEMPERATURE RANGES
Almost-Empty) to indicate when a selected number of words is stored in
memory. Communication between each port can bypass the FIFOs via two
36-bit mailbox registers. Each mailbox register has a flag to signal when new
mail has been stored. Parity is checked passively on each port and may be
ignored if not desired. Parity generation can be selected for data read from
each port. Two or more devices can be used in parallel to create wider data
paths.
This device is a clocked FIFO, which means each port employs a synchronous
interface. All data transfers through a port are gated to the LOW-to-HIGH
transition of a port clock by enable signals. The clocks for each port are
independent of one another and can be asynchronous or coincident. The
enables for each port are arranged to provide a simple bi-directional interface
between microprocessors and/or buses with synchronous control.
The Full Flag (FFA, FFB) and Almost-Full (AFA, AFB) flag of a FIFO are
two-stage synchronized to the port clock that writes data to its array. The Empty
Flag (EFA, EFB) and Almost-Empty (AEA, AEB) flag of a FIFO are two stage
synchronized to the port clock that reads data from its array.
The IDT723612 is characterized for operation from 0°C to 70°C.
