Specifications of 72V3640L15PF

• Part # Aliases: IDT72V3640L15PF

NOTES:
1. n = PAE offset.
2. For IDT Standard Mode.
3. For FWFT Mode.
4. PAE is asserted LOW on RCLK transition and reset to HIGH on WCLK transition.
5. Select this mode by setting PFM LOW during Master Reset.
NOTES:
1. In IDT Standard mode: D = maximum FIFO depth. D = 1,024 for the IDT72V3640, 2,048 for the IDT72V3650, 4,096 for the IDT72V3660, 8,192 for the IDT72V3670, 16,384 for the
2. In FWFT mode: D = maximum FIFO depth. D = 1,025 for the IDT72V3640, 2,049 for the IDT72V3650, 4,097 for the IDT72V3660, 8,193 for the IDT72V3670, 16,385 for the IDT72V3680
