  • Free-running CLKA and CLKB can be asynchronous or coincident
  • Mailbox bypass Register for each FIFO
  • Dynamic Port B bus sizing of 36 bits (long word), 18 bits (word), and 9 bits (byte)
  • Three modes of byte-order swapping on port B
  • Programmable Almost-Full and Almost-Empty flags
  • Passive parity checking on each port
  • Available in 120-pin TQFP packages
