IDT72V275/72V285 3.3V CMOS SUPERSYNC FIFOTM
32,768 x 18 and 65,536 x 18
NOTES:
1. For IDT Standard mode: D = maximum FIFO depth. D = 32,768 for the IDT72V275 and 65,536 for the IDT72V285.
2. For FWFT mode: D = maximum FIFO depth. D = 32,769 for the IDT72V275 and 65,537 for the IDT72V285.
NOTES:
1. n =
PAE offset.
2. For IDT Standard mode
3. For FWFT mode.
4. tSKEW2 is the minimum time between a rising WCLK edge and a rising RCLK edge to guarantee that
PAE will go HIGH (after one RCLK cycle plus tPAE). If the time between the rising edge of
WCLK and the rising edge of RCLK is less than tSKEW2, then the
PAE deassertion may be delayed one extra RCLK cycle.
5.
PAE is asserted and updated on the rising edge of WCLK only.
