• Supports clock frequencies up to 100 MHz

• 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)

DESCRIPTION:

• Two independent clocked FIFOs buffering data in opposite direc-

tions

• 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
