configuration.
Errata History
Errata Description
1.
Limitation to the operating conditions inside a timing and data marginal
configuration.
Rising edge of READ from 0 ns up to 8 ns (typical) before the falling edge of
WRITE when only one data is left to read.
See Figure 1 for behavior description.
Failure Mode:
Empty flag glitch and following data shift out 2nd byte corruption occurs when the
rising edge of the first "READ" for data shift out occurs before falling edge of the
third "WRITE" for data shift in.
Worst Case Range:
between 0 ns and 11 ns
Temperature = 125C
Voltage = 4.5V
Characterization:
-55C / 5.5V: 6 ns
25C / 5V:
8 ns
125C / 4.5V: 11 ns
Workaround
These FIFOs are functional outside of the above timing and data marginal
configuration.
The recommended action is to avoid this particular configuration
.
Please contact Atmel for a case by case application conditions analysis.
