IDT72V3640/50/60/70/80/90 3.3V HIGH DENSITY SUPERSYNC IITM 36-BIT FIFO
1,024 x 36, 2,048 x 36, 4,096 x 36, 8,192 x 36, 16,384 x 36 and 32,768 x 36
APRIL 6, 2006
NOTES:
1. If the part is empty at the point of Retransmit, the empty flag (
EF) will be updated based on RCLK (Retransmit clock cycle), valid data will also appear on the output.
2.
OE = LOW.
3. W1 = first word written to the FIFO after Master Reset, W2 = second word written to the FIFO after Master Reset.
4. No more than D - 2 may be written to the FIFO between Reset (Master or Partial) and Retransmit setup. Therefore,
FF will be HIGH throughout the Retransmit setup procedure.
D = 1,024 for IDT72V3640, 2,048 for IDT72V3650, 4,096 for IDT72V3660, 8,192 for IDT72V3670, 16,384 for the IDT72V3680 and 32,768 for the IDT72V3690.
5. There must be at least two words written to the FIFO before a Retransmit operation can be invoked.
6. RM is set LOW during MRS.
