DESCRIPTION:

The IDT72V3622/72V3632/72V3642 are functionally compatible versions of the IDT723622/723632/723642, designed to run off a 3.3V supply for exceptionally low-power consumption. These devices are monolithic, highspeed, low-power, CMOS Bidirectional SyncFIFO (clocked) memories which support clock frequencies up to 100MHz and have read access times as fast as 6.5ns.

FEATURES:

? Memory storage capacity:

IDT72V3622 – 256 x 36 x 2

IDT72V3632 – 512 x 36 x 2

IDT72V3642 – 1,024 x 36 x 2

? Supports clock frequencies up to 100 MHz

? Fast access times of 6.5ns

? 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

? Mailbox bypass register for each FIFO

? Programmable Almost-Full and Almost-Empty flags

? Microprocessor Interface Control Logic

? FFA/IRA, EFA/ORA, AEA, and AFA flags synchronized by CLKA

? FFB/IRB, EFB/ORB, AEB, and AFB flags synchronized by CLKB

? Select IDT Standard timing (using EFA, EFB, FFA and FFB flags functions) or First Word Fall Through timing (using ORA, ORB, IRA and IRB flag functions)

? Available in 132-pin Plastic Quad Flatpack (PQFP) or space-saving 120-pin Thin Quad Flatpack (TQFP)

? Functionally compatible to the 5V operating IDT723622/723632/ 723642

? Industrial temperature range (–40οC to +85οC) is available
