DESCRIPTION
The IDT72V3652/72V3662/72V3672 are pin and functionally compatible
versions of the IDT723652/723662/723672, designed to run off a 3.3V supply
for exceptionally low-power consumption. These devices are monolithic, high-speed, low-power, CMOS Bidirectional SyncFIFO (clocked) memories which

FEATURES

   IDT72V3672 – 8,192 x 36 x 2
• Supports clock frequencies up to 100MHz
• 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)
• Pin and functionally compatible versions of the 5V operating IDT723652/723662/723672
