IDT723651

CMOS SyncFIFO™ 512 x 36, 1024 x 36, 2048 x 36 Integrated Device Technology, Inc. IDT723631 IDT723641 IDT723651 FEATURES: Free-running CLKA and CLKB can be asynchronous or coincident (permits simultaneous reading and writing of data on a single clock edge) Clocked FIFO buffering data from Port A to Port B Storage capacity: IDT723631 - 512 x 36 IDT723641 - 1024 x 36 IDT723651 - 2048 x 36 Synchronous read retransmit capability Mailbox register in each direction Programmable Almost-Full and Almost-Empty flags Microprocessor interface control logic Input-Ready (IR) and Almost-Full (AF) flags synchronized by CLKA Output-Ready (OR) and Almost-Empty (AE) flags synchronized by CLKB Low-power 0.8-micron advanced CMOS technology Supports clock frequencies up to 67 MHz Fast access times of 11 ns Available in 132-pin plastic quad flat package (PQF) or space-saving 120-pin thin quad flat package (TQFP) Industrial temperature range (-40°C to +85°C) is available, tested to military electrical specifications DESCRIPTION: The IDT723631/723641/723651 is a monolithic highspeed, low-power, CMOS clocked FIFO memory. It supports clock frequencies up to 67 MHz and has read access times as fast as 12ns. The 512/1024/2048 x 36 dual-port SRAM FIFO buffers data from port A to Port B. The FIFO memory has retransmit capability, which allows previously read data to be accessed again. The FIFO has flags to indicate empty and full conditions and two programmable flags (almost ...
