• Description: FIFO
• Manufacturer: IDT

Specifications of 72V263L6PF8

• Part # Aliases: IDT72V263L6PF8

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. If x18 Input or x18 Output bus Width is selected, D = 512 for the IDT72V223, 1,024 for the IDT72V233, 2,048 for the IDT72V243,
2. In FWFT mode: D = maximum FIFO depth. If x18 Input or x18 Output bus Width is selected, D = 513 for the IDT72V223, 1,025 for the IDT72V233, 2,049 for the IDT72V243, 4,097
