DESCRIPTION
The IDT723612 is a monolithic high-speed, low-power CMOS bi-directional clocked FIFO memory. It supports clock frequencies up to 67 MHz and has read access times as fast as 10ns. Two independent 64 x 36 dual-port SRAM FIFOs on board the chip buffer data in opposite directions.

FEATURES
• Free-running CLKA and CLKB can be asynchronous or
   coincident (simultaneous reading and writing of data on a
   single clock edge is permitted)
• Two independent clocked FIFOs (64 x 36 storage capacity
   each) buffering data in opposite directions
• Mailbox bypass Register for each FIFO
• Programmable Almost-Full and Almost-Empty Flags
• Microprocessor interface control logic
• EFA, FFA, AEA, and AFA flags synchronized by CLKA
• EFB, FFB, AEB, and AFB flags synchronized by CLKB
• Passive parity checking on each port
• Parity generation can be selected for each port
• Supports clock frequencies up to 67 MHz
• Fast access times of 10ns
• Available in 132-pin plastic quad flat package (PQF) or
   spacesaving 120-pin thin quad flat package (TQFP)
• Industrial temperature range (–40°C to +85°C) is available
