SAM4S Series [DATASHEET]
11100F–ATARM–29-Jan-14
44.12 AC Characteristics
44.12.1 Master Clock Characteristics
44.12.2 I/O Characteristics
Criteria used to define the maximum frequency of the I/Os:
Output duty cycle (40%-60%)
Minimum output swing: 100 mV to VDDIO - 100 mV
Minimum output swing: 100 mV to VDDIO - 100 mV
Addition of rising and falling time inferior to 75% of the period
Notes: 1. Pin Group 1 = PA14, PA29
2. Pin Group 2 = PA[4–11], PA[15–25], PA[30–31], PB[0–9], PB[12–14], PC[0–31]
3. Pin Group 3 = PA[12–13], PA[26–28], PA[30–31]
