PRELIMINARY
Notes:
33. 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.
34. D = Maximum FIFO Depth = 1K for the CY7C43642AV, 4K for the CY7C43662AV, and 16K for the CY7C43682AV.
35. If Port B size is word or byte, t
is referenced to the rising CLKB edge that writes the last word or byte of the long word, respectively.
36. 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.
37. FIFO2 Write (CSB = LOW, W/RB = LOW, MBB = LOW), FIFO2 Read (CSA = LOW, W/RA = LOW, MBA = LOW). Data in the FIFO2 output register has been
read from the FIFO.
38. 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.
