72V3641数据手册集成电路（IC）的FIFO存储器规格书PDF

描述 Description

The 72V3641is a 1K x 36 Sync FIFO memory that is a 3.3V version of the 723641.It supports clock frequencies up to 67 MHz and has read access times as fast as 10ns. The FIFO memory has retransmit capability, which allows previously read data to be accessed again. The FIFO operates in First Word Fall Through mode.Communication between each port may take place with two 36-bit mailbox registers. The enables for each port are arranged to provide a simple interface between microprocessors and/or buses with synchronous control.
