COMMERCIAL TEMPERATURE RANGE
FEATURES:
Two independent clocked FIFOs (64 x 36 storage capacity each)
buffering data in opposite directions
Supports clock frequencies up to 83 MHz
Fast access times of 8ns
Free-running CLKA and CLKB can be asynchronous or
coincident (simultaneous reading and writing of data on a
single clock edge is permitted)
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
Available in space saving 120-pin thin quad flat package (TQFP)
Green parts available, see ordering information
