IDT72V201/72V211/72V221/72V231/72V241/72V251 3.3V CMOS SyncFIFO

NOTES:
1. m =
PAF offset.
2. 256 - m words in FIFO for IDT72V201, 512 - m words for IDT72V211, 1,024 - m words for IDT72V221, 2,048 - m words for IDT72V231, 4,096 - m words for IDT72V241, 8,192 - m
words for IDT72V251.
3. tSKEW2 is the minimum time between a rising RCLK edge and a rising WCLK edge for
PAF to change during that clock cycle. If the time between the rising edge of RCLK and
the rising edge of WCLK is less than tSKEW2, then
PAF may not change state until the next WCLK rising edge.
4. If a write is performed on this rising edge of the write clock, there will be Full - (m-1) words in the FIFO when
PAF goes LOW.
NOTES:
1. n =
PAE offset.
2. tSKEW2 is the minimum time between a rising WCLK edge and a rising RCLK edge for
PAE to change during that clock cycle. If the time between the rising edge of WCLK and
the rising edge of RCLK is less than tSKEW2, then
PAE may not change state until the next RCLK rising edge.
3. If a read is performed on this rising edge of the read clock, there will be Empty + (n-1) words in the FIFO when
PAE goes LOW.
