JUNE 1, 2010
NOTES:
1. m =
PAF offset .
2. D = maximum FIFO depth.
In IDT Standard mode: if x18 Input or x18 Output bus Width is selected, D = 131,072 for the IDT72V2103 and 262,144 for the IDT72V2113. If both x9 Input and x9 Output bus Widths
are selected, D = 262,144 for the IDT72V2103 and 524,288 for the IDT72V2113.
In FWFT mode: if x18 Input or x18 Output bus Width is selected, D = 131,073 for the IDT72V2103 and 262,145 for the IDT72V2113. If both x9 Input and x9 Output bus Widths
are selected, D = 262,145 for the IDT72V2103 and 524,289 for the IDT72V2113.
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.
