DESCRIPTION:
The IDT723622/723632/723642 are a monolithic, high-speed, low-power,
CMOS Bidirectional SyncFIFO (clocked) memory which supports clock fre-
quencies up to 83MHz and have read access times as fast as 8ns. Two
independent 256/512/1,024 x 36 dual-port SRAM FIFOs on board each chip
buffer data in opposite directions. Communication between each port may
bypass the FIFOs via two 36-bit mailbox registers. Each mailbox register has
a flag to signal when new mail has been stored.
These devices are a synchronous (clocked) FIFO, meaning 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
