DESCRIPTION
The IDT723652/723662/723672 is a monolithic, high-speed, low-power,
CMOS Bidirectional SyncFIFO (clocked) memories which support clock
frequencies up to 83MHz and have read access times as fast as 8ns. Two
independent 2,048/4,096/8,192 x 36 dual-port SRAM FIFOs on board each
chipbufferdatainoppositedirections. Communicationbetweeneachportmay
bypass the FIFOs via two 36-bit mailbox registers. Each mailbox register has
a flag to signal when new mail has been stored.
