5. Module: RC Oscillator
TABLE 4:
6. Module: Brown-Out Reset (BOR)
TABLE 5:
DS80089A-page 6
The percentage variation indicated here is part-to-part variation due to normal process distribution. The variation
indicated is ±3 standard deviation from the average value for V
Param
D005
No.
The table for RC Oscillator Frequencies in the
Device Characterization section of the Data Sheet
is incorrect. The correct characterization informa-
tion is shown in Table 4.
The levels specified for the BOR module thresh-
olds (parameter D005) have changed. The new
values are shown in Table 5.
