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

each port are independent of one another and can be asynchronous or
