DESCRIPTION

The IDT72V3682/72V3692/72V36102 are designed to run off a 3.3V supply for exceptionally low-power consumption. These devices are monolithic, high-speed, low-power, CMOS Bidirectional SyncFIFO (clocked) memories which support clock frequencies up to 100MHz and have read access times as fast as 6.5ns. Two independent 16,384/32,768/65,536 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.
