IDT723622 IDT723632 IDT723642 FEATURES: Free-running CLKA and CLKB may be asynchronous or coincident (simultaneous reading and writing of data on a single clock edge is permitted) Two independent clocked FIFOs buffering data in opposite directions Memory storage capacity: IDT723622–256 x 36 x 2 IDT723632–512 x 36 x 2 IDT723642–1024 x 36 x 2 Mailbox bypass register for each FIFO Programmable Almost-Full and Almost-Empty flags Microprocessor Interface Control Logic IRA, ORA, AEA, and AFA flags synchronized by CLKA IRB, ORB, AEB, and AFB flags synchronized by CLKB Supports clock frequencies up to 67MHz Fast access times of 11ns Available in 132-pin Plastic Quad Flatpack (PQF) or space-saving 120-pin Thin Quad Flatpack (PF) Low-power 0.8-Micron Advanced CMOS technology Industrial temperature range (-40oC to +85oC) is available, tested to military electrical specifications DESCRIPTION: The IDT723622/723632/723642 is a monolithic, high-speed, low-power, CMOS Bidirectional SyncFIFO (clocked) memory which supports clock frequencies up to 67MHz and have read access times as fast as 11ns. Two independent 256/512/ 1024x36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions. Each FIFO has flags to indicate empty and full conditions and two programable flags (almost FUNCTIONAL BLOCK DIAGRAM CLKA MBF1 Mail 1 Register 256 x 36 512 x 36 1024 x 3...
