IDT723612L15PF集成電路（IC）的FIFO存儲器規(guī)格書PDF中文資料

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

? Green parts available, see ordering information
