3.3 VOLT CMOS SyncFIFO^TM

512 x 36

1,024 x 36

72V3631

72V3641

• Available in space-saving 120-pin thin quad flat package (TQFP)

• Pin and functionally compatible versions of the 5V operating

723631/723641

• Easily expandable in width and depth

• Green parts are available, see ordering information

FEATURES

• Storage capacity:

72V3631 - 512 x 36

72V3641 - 1,024 x 36

• Supports clock frequencies up to 67 MHz

• Fast access times of 10ns

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

• Output Ready (OR) and Almost-Empty (AE) flags synchronized

by CLKB
