is stored in memory. Communication between each port may take place with
two 36-bit mailbox registers. Each mailbox register has a flag to signal when
newmailhasbeenstored. Twoormoredevicesmaybeusedinparalleltocreate
wider data paths. Expansion is also possible in word depth.
These devices are 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 continuous (free-running) port clock by enable signals.
The continuous 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 interface between microprocessors and/or buses with
synchronous control.
TheInputReady(IR)flagandAlmost-Full(
AF)flagoftheFIFOaretwo-stage
synchronized to CLKA. The Output Ready (OR) flag and Almost-Empty (
AE)
flag of the FIFO are two-stage synchronized to CLKB. Offset values for the
Almost-FullandAlmost-EmptyflagsoftheFIFOcanbeprogrammedfromport
A or through a serial input.
The IDT72V3631/72V3641/72V3651 are characterized for operation from
0
