PRELIMINARY
Notes:
43. D = Maximum FIFO Depth = 256 for the CY7C43624, 512 for the CY7C43634, 1K for the CY7C43644, 4K for the CY7C43664, and 16K for the CY7C43684.
44. t
is the minimum time between a rising CLKA edge and a rising CLKB edge for AFA to transition HIGH in the next CLKA cycle. If the time between the
rising CLKA edge and rising CLKB edge is less than t
, then AFA may transition HIGH one CLKB cycle later than shown.
45. If Port B size is word or byte, AFB is set LOW by the last word or byte write of the long word, respectively.
46. t
is the minimum time between a rising CLKB edge and a rising CLKA edge for AFB to transition HIGH in the next CLKB cycle. If the time between
the rising CLKB edge and rising CLKA edge is less than t
SKEW2
, then AFB may transition HIGH one CLKA cycle later than shown.
