描述
The 72V3652 is a 3.3V CMOS Bidirectional SyncFIFO (clocked) memories. Two independent 2K x 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions. The 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 bidirectional interface between microprocessors and/or buses with synchronous control.
