FEATURES:

• Storage capacity:

IDT723631 - 512 x 36

IDT723641 - 1,024 x 36

IDT723651 - 2,048 x 36

• Supports clock frequencies up to 67 MHz

• Fast access times of 11ns

DESCRIPTION:

• Free-running CLKA and CLKB can be asynchronous or coinci-

dent (permits simultaneous reading and writing of data on a

single clock edge)

• Clocked FIFO buffering data from Port A to Port B

• 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

The IDT723631/723641/723651 is a monolithic high-speed, low-power,

CMOS clocked FIFO memory. It supports clock frequencies up to 67 MHz

and has read access times as fast as 12ns. The 512/1,024/2,048 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 ac-

cessed again. The FIFO has flags to indicate empty and full conditions and

two programmable flags (Almost-Full and Almost-Empty) to indicate when a

selected number of words is stored in memory. Communication between

each port may take place with two 36-bit mailbox registers. Each mailbox
