PRELIMINARY
Notes:
43. FIFO1 Write (CSA = LOW, W/RA = HIGH, MBA = LOW), FIFO1 read (CSB = LOW, W/RB = HIGH, MBB = LOW). Data in the FIFO1 output register has been
read from the FIFO.
44. D = Maximum FIFO Depth = 1K for the CY7C43644AV, 4K for the CY7C43664AV, and 16K for the CY7C43684AV.
45. 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.
46. If Port B size is word or byte, AFB is set LOW by the last word or byte write of the long-word, respectively.
47. 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.
