IDT72V36100/72V36110 3.3V HIGH DENSITY SUPERSYNC IITM 36-BIT FIFO
65,536 x 36 and 131,072 x 36
OCTOBER 22, 2008
NOTES:
1. m =
PAF offset.
2. D = maximum FIFO depth.
In IDT Standard mode: D = 65,536 for the IDT72V36100 and 131,072 for the IDT72V36110.
In FWFT mode: D = 65,537 for the IDT72V36100 and 131,073 for the IDT72V36110.
3. tSKEW2 is the minimum time between a rising RCLK edge and a rising WCLK edge to guarantee that
PAF will go HIGH (after one WCLK cycle plus tPAFS). If the time between the
rising edge of RCLK and the rising edge of WCLK is less than tSKEW2, then the
PAF deassertion time may be delayed one extra WCLK cycle.
4.
PAF is asserted and updated on the rising edge of WCLK only.
5. Select this mode by setting PFM HIGH during Master Reset.
