COMMERCIAL TEMPERATURE RANGE
FEATURES:
Two independent clocked FIFOs (64 x 36 storage capacity each)
buffering data in opposite directions
Supports clock frequencies up to 67 MHz
Fast access times of 10 ns
Free-running CLKA and CLKB can be asynchronous or coinci-
dent (simultaneous reading and writing of data on a single
clock edge is permitted)
Mailbox bypass Register for each FIFO
Dynamic Port B bus sizing of 36 bits (long word), 18 bits (word),
and 9 bits (byte)
Selection of Big- or Little-Endian format for word and byte bus
sizes
Three modes of byte-order swapping on port B
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
